• Control Outbreaks on the Network on page 1-4

• Manage Client Server Messaging Security Groups on page 1-4
• Protect Clients from Hacker Attacks with Personal Firewall on page 1-5
• Protect POP3 Mail Messages on page 1-5

Analyze Your Network’s Protection

Client Server Messaging Security can generate various types of logs, including virus
logs, system event logs, and update logs. Use these logs to verify update deployment,
check client-server communication, and determine which computers are vulnerable
to infection.
Also use log information as a basis for designing and redesigning network protection,
identifying which computers are at a higher risk of infection, and changing the
antivirus settings accordingly for these computers.

Enforce Antivirus Policies

Client Server Messaging Security provides three types of scans: Scheduled Scan,
Manual Scan, and Real-time Scan. Enforce your organization’s antivirus policies by
configuring these three types of scans. Specify the types of files to scan and the
action to take when Client Server Messaging Security finds a virus.
To apply uniform scan settings to all clients, choose not to grant privileges to clients
and lock the client program with a password to prevent users from removing or
turning it off.

Protect Clients and Servers from Spyware/Grayware

In addition to protecting against viruses, Client Server Messaging Security also
checks for and removes any spyware installed on clients and servers. As with
antivirus scanning, three types of anti-spyware scans are available – Scheduled Scan,
Manual Scan, and Real-time Scan.
Each scan type provides the option to run either a full scan (all files and registries) or
a quick scan (registry only). Available scan actions for spyware include Clean
(remove) and Pass (record to log only).

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

Update Your Protection

Virus writers create new viruses and release them everyday. To ensure that you stay
protected against the latest threats, you must periodically update the Client Server
Messaging Security components. Trend Micro usually releases new virus pattern
files on a daily basis.

Perform Scans from One Location

The Security Dashboard provides the option of performing Scan Now (Manual Scan)
and configuring scheduled scans on clients to run during off-peak hours when client
CPU usage is low.

Quarantine Infected Files

You can specify a quarantine folder to control live viruses and infected files. The
Trend Micro Security Server then automatically forwards infected files to the
quarantine folder.

Control Outbreaks on the Network

Enabling Outbreak Defense and setting up outbreak notifications helps you to
respond quickly to outbreaks that may be developing.
Outbreak Defense helps stop outbreaks from overwhelming your network by
blocking shared folders and vulnerable ports on clients, by denying write access to
folders, and by blocking attachments and filtering content. Download the latest
pattern file and then perform Scan Now on all clients to remove any existing threats.

Manage Client Server Messaging Security Groups

A group in Client Server Messaging Security is a cluster of clients that share the
same configuration and run the same tasks. A Client Server Messaging Security
group is different from a Windows domain. There can be several Client Server
Messaging Security groups in any given Windows domain.
Group clients into Client Server Messaging Security groups to simultaneously apply
the same configuration to all group members.

Introducing Trend Micro Client Server Messaging Security for SMB

Protect Clients from Hacker Attacks with Personal Firewall

Help protect clients running Windows 2000/XP/Server 2003 from hacker attacks and
network viruses by creating a barrier between the client machine and the network.
Personal Firewall allows you to block or allow certain types of network traffic.
Additionally, Personal Firewall will identify patterns in network packets that may
indicate an attack on clients.

Protect POP3 Mail Messages

Protects client machines running Windows 2000/XP/Server 2003 from infected Post
Office Protocol 3 (POP3) mail messages and attachments. When a virus is detected,
the user can choose to delete, clean, or ignore the mail message containing the virus.

Benefits and Capabilities

Trend Micro Client Server Messaging Security for SMB brings many benefits to your
organization by providing a comprehensive yet user-friendly method of managing
your antivirus policies. The following is a summary of the advantages you can

technologies such as Java, CGI, HTML, and HTTP.

Outbreak Defense
Use Outbreak Defense to take preemptive steps to secure your network. Outbreak
Defense first informs you of the latest threats, and then takes action to shield your
network and clients from the threat. While Outbreak Defense is protecting your
network and clients, TrendLabs is busy creating a solution to the threat. As soon as
TrendLabs finds a solution, they release updated components. The Security Server
then downloads and deploys the updated components to clients. For the last step,

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

Outbreak Defense cleans up any virus remnants, and repairs files and directories that
have been damaged by the threat.
Using Outbreak Defense, you can take the following actions in the event of an
outbreak:
• Block ports to help prevent viruses from infecting files on the network
• Write-protect certain files and directories
• Block certain attachments

Spyware/Grayware Approved List

Certain applications are classified by Trend Micro as spyware/grayware not because
they can cause harm to the system on which they are installed, but because they have
the potential to expose the client or the network to malware or hacker attacks.
Hotbar, for example, is a program that embeds a toolbar into Web browsers. Hotbar
tracks URLs that users visit and records words or phrases that are entered into search
engines. These pieces of information are used to display targeted ads, including
pop-ups, on users' browsers. Since the information that Hotbar collects can
potentially be sent to a third party site and used by malware or hackers to collect
information about your users, Client Server Messaging Security prevents this
application from installing and running by default.
If you want to run Hotbar or any other application that Client Server Messaging
Security classifies as spyware/grayware, you need to add it to the spyware/grayware
approved list.
By preventing potentially risky applications from running and by giving you full
control over the spyware/grayware approved list, Client Server Messaging Security
helps ensure that only the applications you approve run on clients and servers.

Secure Web Console Communication

Client Server Messaging Security provides secure communications between the
Trend Micro Security Server and the Security Dashboard through Secure Socket
Layer (SSL) technology.
The Trend Micro Security Server can generate a certificate for each Web console
session, allowing the Security Dashboard to encrypt data based on Public Key

Client/Server Security & Messaging Security Agents

Trend Micro Client Server Messaging Security Agent

Protect Windows computers from viruses and spyware by installing the Client/Server
Security Agent on each desktop, notebook, and server. The Client/Server Security
Agent provides three methods of scanning: Real-time Scan, Scheduled Scan, Manual
Scan.

2-4
CSM4SMB-v3-AG.book Page 5 Monday, April 23, 2007 10:40 AM

Client Server Messaging Security Components

The Client/Server Security Agent reports to the Trend Micro Security Server from
which it was installed. To provide the server with the very latest client information,
the client sends event status information in real time. Clients report events such as
virus and spyware detection, client startup, client shutdown, start of scan, and
completion of an update.
Configure scan settings on clients from the Trend Micro Security Dashboard for
SMB. To enforce uniform desktop protection across the network, choose not to grant
the clients privileges to modify the scan settings or to remove the client program.

Trend Micro Messaging Security Agent

Protect Exchange servers from viruses by installing the Messaging Security Agent on
each Exchange server. The Messaging Security Agent protects the Exchange server
against viruses, Trojans, worms, and other malware. It also provides spam blocking,
content filtering, and attachment blocking for added security. The Messaging
Security Agent provides three methods of scanning – Real-time Scan, Scheduled
Scan, and Manual Scan.
The Messaging Security Agent reports to the Trend Micro Security Server from
which it was installed. The Messaging Security Agent sends events and status
information to the Security Server in real time. You can view the events and status
information from the Security Dashboard.

Client Server Messaging Security Updateable

Components
Client Server Messaging Security uses the following components to scan for,
identify, and perform damage cleanup tasks to help protect and clean clients:
• Virus pattern– A file that helps Client Server Messaging Security identify virus

About the Trend Micro Scan Engine

At the heart of all Trend Micro products lies a scan engine. Originally developed in
response to early file-based computer viruses, the scan engine today is exceptionally
sophisticated and capable of detecting Internet worms, mass-mailers, Trojan horse
threats, phish sites, and network exploits as well as viruses. The scan engine detects
two types of threats:
• Actively circulating – Threats that are actively circulating on the Internet
• Known and controlled – Controlled viruses not in circulation, but that are
developed and used for research
Rather than scan every byte of every file, the engine and pattern file work together to
identify not only tell-tale characteristics of the virus code, but the precise location
within a file where the virus would hide. If Client Server Messaging Security detects
a virus, it can remove it and restore the integrity of the file.
The scan engine includes an automatic clean-up routine for old virus pattern files (to
help manage disk space), as well as incremental pattern updates (to help manage
bandwidth).
In addition, the scan engine is able to decrypt all major encryption formats (including
MIME and BinHex). It also recognizes and scans common compression formats,
including Zip, Arj, and Cab. Client Server Messaging Security also allows you to
determine how many layers of compression to scan (up to a maximum of six) for
compressed files contained within a file.
It is important that the scan engine remain current with new threats. Trend Micro
ensures this in two ways:
• Frequent updates to the virus pattern file

2-7
CSM4SMB-v3-AG.book Page 8 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

• Technological upgrades in the engine software prompted by a change in the nature

of virus threats, such as a rise in mixed threats like SQL Slammer
The Trend Micro scan engine is certified annually by international computer security
organizations, including ICSA (International Computer Security Association)

Scan Engine Updates

By storing the most time-sensitive virus information in the virus pattern file, Trend
Micro is able to minimize the number of scan engine updates while at the same time
keeping protection up-to-date. Nevertheless, Trend Micro periodically makes new
scan engine versions available. Trend Micro releases new engines under the
following circumstances:
• New scanning and detection technologies are incorporated into the software
• A new, potentially harmful virus is discovered that the scan engine cannot handle
• Scanning performance is enhanced
• Support is added for additional file formats, scripting languages, encoding, and/or
compression formats
To view the version number for the most current version of the scan engine, visit the
Trend Micro Web site:
http://www.trendmicro.com

About the Virus Pattern File

The Trend Micro scan engine uses an external data file, called the virus pattern file. It
contains information that helps Client Server Messaging Security identify the latest
viruses and other Internet threats such as Trojan horses, mass mailers, worms, and
mixed attacks. New virus pattern files are created and released several times a week,
and any time a particularly threat is discovered.
All Trend Micro antivirus programs using the ActiveUpdate function can detect the
availability of a new virus pattern file on the Trend Micro server. Administrators can
schedule the antivirus program to poll the server every week, day, or hour to get the
latest file.

2-8
CSM4SMB-v3-AG.book Page 9 Monday, April 23, 2007 10:40 AM

Client Server Messaging Security Components

Tip: Trend Micro recommends scheduling automatic updates at least hourly. The default
setting for all Trend Micro products is hourly.

You can download virus pattern files from the following Web site, where you can
also find the current version, release date, and a list of all the new virus definitions
included in the file:
http://www.trendmicro.com/download/pattern.asp

The scan engine works together with the virus pattern file to perform the first level of
detection, using a process called pattern matching. Since each virus contains a unique
“signature” or string of telltale characters that distinguish it from any other code, the
virus experts at TrendLabs™ capture inert snippets of this code in the pattern file.
The engine then compares certain parts of each scanned file to the pattern in the virus
pattern file, looking for a match. When the engine detects a match, a virus has been
detected and a notification is sent via an email message to the system administrator.

About the Virus Cleanup Engine

Damage Cleanup Services (DCS) makes use of a scanning and cleanup tool called
the Virus Cleanup Engine (DCE) to find and repair damage caused by viruses and
other Internet threats. The Virus Cleanup Engine can find and clean viruses, Trojans,
and other malware. The DCE is essentially a software agent that makes use of a
database to find targeted machines and evaluate whether viruses or other Internet
threats have affected them. DCE resides on a single machine and deploys to the
targeted client machines on the network at the time of scanning.
The Virus Cleanup Engine uses damage cleanup templates that contain information
that DCE uses to restore damage caused by the latest known viruses, malware, or
other Internet threats. DCS regularly updates these templates. When you install DCS,
you are installing the version of the Virus Cleanup Engine that was current as of the
release of this product. TrendLabs updates the Virus Cleanup Pattern frequently,
therefore, Trend Micro recommends that you update your components immediately
after you have installed and activated Damage Cleanup Services.

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

About the Virus Cleanup Pattern

The Virus Cleanup Engine uses the Virus Cleanup Pattern to identify Trojans,
network viruses, and active malware.

About the Common Firewall Driver

The Common Firewall Driver has two purposes. The Common Firewall Driver, in
conjunction with the user-defined settings of the Personal Firewall, blocks ports
during an outbreak. The Common Firewall Driver uses the Network Virus Pattern
file to detect network viruses.

About the Network Virus Pattern File

The Network Virus Pattern file contains a regularly updated database of packet-level
network virus patterns. Trend Micro updates the network virus pattern file
frequently, as often as hourly, to ensure Client Server Messaging Security can
identify new network viruses.

About the Vulnerability Pattern File

Client Server Messaging Security deploys the Vulnerability Pattern file after
updating components. The Vulnerability Pattern file is used in the Outbreak Defense
> Potential Threat screen when the Scan for Vulnerability Now tool is used, or when
scheduled Vulnerability Assessment is triggered, or whenever a new Vulnerability
Pattern file is downloaded. As soon as the Trend Micro Security Server completes
downloading a new Vulnerability Pattern file, Client Server Messaging Security
starts to scan clients for vulnerabilities.

About Hot Fixes, Patches, and Service Packs

After an official product release, Trend Micro often develops hot fixes, patches, and
service packs to address issues, enhance product performance, or add new features.
The following is a summary of the items Trend Micro may release:
• Hot fix – A workaround or solution to a single, customer-reported issue. Hot fixes
are issue-specific, and therefore are not released to all customers. Windows hot

2-10
CSM4SMB-v3-AG.book Page 11 Monday, April 23, 2007 10:40 AM

Client Server Messaging Security Components

fixes include a Setup program, while non-Windows hot fixes do not. Typically,
you need to stop the program daemons, copy the file to overwrite its counterpart in
your installation, and restart the daemons.
• Security Patch – A hot fix focusing on security issues and that is suitable for
deployment to all customers. Windows security patches include a Setup program,
while non-Windows patches commonly have a setup script.
• Patch – A group of hot fixes and security patches that solve multiple program
issues. Trend Micro makes patches available on a regular basis. Windows patches
include a Setup program, while non-Windows patches commonly have a setup
script.
• Service Pack – A consolidation of hot fixes, patches, and feature enhancements
significant enough to be a product upgrade. Both Windows and non-Windows
service packs include a Setup program and setup script.
You can obtain hot fixes from your Technical Account Manager. Check the Trend
Micro Knowledge Base to search for released hot fixes:
http://esupport.trendmicro.com/support

Check the Trend Micro Web site regularly to download patches and service packs:
http://www.trendmicro.com/download

Note: All releases include a readme file with the information you need to install, deploy, and
configure your product. Read the readme file carefully before installing the hot fix,
patch, or service pack file(s).

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

WARNING! You have the option of installing Apache Web server when you install the Trend
Micro Security Server. By default, the administrator account is the only account
created on the Apache Web server. Trend Micro recommends creating another
account from which to run the Web server; otherwise a hacker may be able to
take control of the Apache server and compromise the Trend Micro Security
Server.
Before installing the Apache Web server, refer to the Apache Web site for the
latest information on upgrades, patches, and security issues:
http://www.apache.org.

Note: If using Remote install to install the Client/Server Security Agent on Windows
Vista/XP clients, you must disable Simple File Sharing unless they are part of a
domain (see your Windows documentation for instructions).

Other Requirements
• Administrator or Domain Administrator access on the computer hosting the
Security Server
• File and printer sharing for Microsoft Networks installed
• Transmission Control Protocol/Internet Protocol (TCP/IP) support installed

Note: If Microsoft ISA Server or a proxy product is installed on the network, you need to
enable the HTTP port ( 80 or 8080) and SSL port (443 or 4343) to enable access to the
Security Dashboard and to ensure that client-server communication can be established.

CSM4SMB-v3-AG.book Page 7 Monday, April 23, 2007 10:40 AM

Planning for Installation of Client Server Messaging Security

Other Installation Considerations

Server Performance
Ideally, the computer on which the Trend Micro Security Server is installed would
have the following:
• Single 2.8~3.2 GHz processor
• 500 MB of memory

Location of the Trend Micro Security Server

Client Server Messaging Security is flexible enough to accommodate a variety of
network environments. For example, you can position a firewall between the Trend
Micro Security Server and clients running the Client/Server Security Agent, or
position both the Trend Micro Security Server and all Client/Server Security Agent
clients behind a single network firewall.
Ideally, the Security Server should be located behind a firewall and there should not
be a firewall between the clients and the security server.
If managing more than one site, having a security server at the main site as well as at
each managed site will reduce bandwidth usage between the main site and managed
sites, and speed up pattern deployment rates.
If client computers have the Windows XP Firewall enabled, Client Server Messaging
Security will automatically add it to the Exception list.

Note: If a firewall is located between the Trend Micro Security Server and its clients, you
must configure the firewall to allow traffic between the client listening port and the
Trend Micro Security Server’s listening port (see Understanding Client/Server
Security Ports on page 4-7for more information on the types of ports the client and
Trend Micro Security Server use to communicate)

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

Number of Clients
A client is a computer that has the Client/Server Security Agent software installed on
it. clients can be desktops, servers (even Exchange servers), and notebook computers,
including those that belong to users who telecommute or connect to the corporate
network from their homes.
If you have a heterogeneous client base (that is, if your network has different
Windows operating systems, such as Windows Vista, 2000, XP, or Server 2003),
identify how many clients are using a specific Windows version. Use this
information to decide which client deployment method will work best in your
environment.

Note: A single Trend Micro Security Server can manage up to 2500 clients. If you have
more then this amount, Trend Micro suggests installing more than one Trend Micro
Security Server.

Network Traffic Considerations

When planning for deployment, consider the network traffic that Client/Server
Security will generate. Client/Server Security generates network traffic when the
Trend Micro Security Server and clients communicate with each other.
The Trend Micro Security Server generates traffic when it does the following:
• Connects to the Trend Micro ActiveUpdate server to check for and download
updated components
• Notifies clients to download updated components
• Notifies clients about configuration changes
The client generates traffic when it does the following:
• Starts up
• Performs scheduled update
• Switches between roaming mode and normal mode
• Performs Update Now
• Generates a Virus Log

Planning for Installation of Client Server Messaging Security

Network Traffic During Pattern File Updates

Significant network traffic is generated whenever TrendLabs releases an updated
version of any of the following items:
• Virus pattern, Virus scan engine 32-bit, Virus scan engine 64-bit
• IntelliTrap pattern, IntelliTrap exception pattern
• Virus cleanup template, Virus cleanup engine 32- bit
• Messaging Security Agent scan engine
• Spyware pattern, spyware active-monitoring pattern, anti-rootkit driver (for 32-bit
systems only), and spyware scan engine
• Anti-spam pattern, Anti-spam engine
• Vulnerability pattern
• Common Firewall pattern, Common Firewall driver 32-bit
To reduce network traffic generated during pattern file updates, Client Server
Messaging Security uses a method called incremental update. Instead of
downloading the full updated pattern file every time, the Trend Micro Security
Server only downloads the new patterns that have been added since the last release.
The Trend Micro Security Server merges the new patterns with the old pattern file.
Regularly updated clients only have to download the incremental pattern, which is
approximately 5KB to 200KB. The full pattern is approximately 13MB when
compressed and 20MB to 30MB when uncompressed and takes substantially longer
to download.
Trend Micro releases new pattern files daily. However, if a particularly damaging
virus is actively circulating, Trend Micro releases a new pattern file as soon as a
detection routine for the threat is available.

Using Update Agents to Reduce Network Bandwidth

Consumption During Updates
If you identify sections of your network between clients and the Trend Micro
Security Server as "low-bandwidth" or "heavy traffic", you can specify Client/Server
Security Agent clients to act as update sources (Update Agents) for other clients. This
helps distribute the burden of deploying components to all clients.

3-9
CSM4SMB-v3-AG.book Page 10 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

For example, if your network is segmented by location, and the network link between
segments experiences a heavy traffic load, Trend Micro recommends allowing at
least one client on each segment to act as an Update Agent.

Deciding on a Dedicated Server

When selecting a server that will host Client Server Messaging Security, consider the
following:
• How much CPU load is the server carrying?
• What other functions does the server perform?
If you are installing Client Server Messaging Security on a server that has other uses
(for example, application server), Trend Micro recommends that you install on a
server that is not running mission-critical or resource-intensive applications.

Location of the Program Files

During the Trend Micro Security Server installation, specify where to install the
program files on the clients. Either accept the default client installation path or
modify it. Trend Micro recommends that you use the default settings, unless you
have a compelling reason (such as insufficient disk space) to change them.
The default client installation path is:
C:\Program Files\Trend Micro\Security Server

Number of Groups
A group in Client Server Messaging Security is a cluster of clients that share the
same configuration and run the same tasks. By clustering your clients into groups,
you can simultaneously configure, manage, and apply the same configuration to all
group members.
A Client Server Messaging Security group is different from a Windows domain.
There can be several Client Server Messaging Security groups in one Windows
domain.
For ease of management, plan how many Client Server Messaging Security groups to
create. You can group clients based on the departments they belong to or the

3-10
CSM4SMB-v3-AG.book Page 11 Monday, April 23, 2007 10:40 AM

functions they perform. Alternatively, you can group clients that are at a greater risk
of infection and apply a more secure configuration to all of them.

Third Party Antivirus Applications

Trend Micro highly recommends removing third party antivirus applications from
the computer on which you will install the Trend Micro Security Server. The
existence of other antivirus applications on the same computer may hinder proper
Trend Micro Security Server installation and performance.

Note: Client Server Messaging Security cannot uninstall the server component of any
third-party antivirus product, but can uninstall the client component (see Migrating
from Third-party Antivirus Applications on page 5-17 for instructions and for a
list of third party applications Client Server Messaging Security can remove).

Known Compatibility Issues

This section explains compatibility issues that may arise if you install the Trend
Micro Security Server on the same computer with certain other third-party
applications. Always refer to the documentation of all third-party applications that
are installed on the same computer on which you will install theTrend Micro Security
Server.

SQL Server
You can scan SQL Server databases; however, this may decrease the performance of
applications that access the databases. Trend Micro recommends excluding SQL
Server databases and their backup folders from Real-time Scan. If you need to scan a
database, perform a manual scan during off-peak hours to minimize the impact of the
scan.

Internet Connection Firewall (ICF)

Windows XP SP2 and Windows Server 2003 provide a built-in firewall named
Internet Connection Firewall (ICF). Trend Micro highly recommends removing any
third-party firewall applications if you want to install Personal Firewall. However, if
you want to run ICF or any other third-party firewall, add the Trend Micro Security
Server listening ports to the firewall exception list (see Understanding Client/Server
Security Ports on page 4-7 for information on listening ports and see your firewall
documentation for details on how to configure exception lists).

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

Information to Prepare Before Performing the Installation

The master installer will prompt you for the following information during
installation:
• Security server details – The domain/hostname or the IP address of the security
server and the target directory where Client Server Messaging Security installs the
the security server files.
• Proxy server details – If a proxy server handles Internet traffic on your network,
you must configure proxy server information (including the user name and
password). This information is necessary to download the latest components from
the Trend Micro update server. You can enter proxy server information during or
after installation. Use the Trend Micro Security Dashboard for SMB to enter
information after installation.
• SMTP server – If using an SMTP server to send notifications, enter the name of
the SMTP server, the port number, and the recipients’ email address.

Note: The installation program will automatically detect the name of the SMTP server and
fill in the field if the SMTP server is on the same computer as the CSM server
installation.

• Dashboard password – To prevent unauthorized access to the Trend Micro

Security Dashboard for SMB, you can specify a password that will be required of
anyone trying to open the console.
• Client unload/uninstall password – Set a password to prevent unauthorized
unloading or removal of the Client/Server Security Agent.
• Client software installation path – Configure the client installation path where
Client/Server Security files will be copied to during client setup.
• Account and Privileges – You must log on with an administrator account with
domain administrator privileges, or with administrator privileges on the local
computer. If you do not log on with domain administrator privileges or local
computer privileges, you must manually create an administrative group before
proceeding with the installation.
• Restarting Exchange services – You do not need to stop Exchange services
before starting the installation or restart them after a successful installation. When

4-6
CSM4SMB-v3-AG.book Page 7 Monday, April 23, 2007 10:40 AM

Client Server Messaging Security Installation Overview

uninstalling or upgrading the Trend Micro Messaging Security Agent, the IIS
Admin service and all related services will automatically be stopped and restarted.

WARNING! If you are installing the Messaging Security Agent on a server that is running
lockdown tools (such as typically implemented for Windows 2000 server with IIS
5.0), remove the lockdown tool so that it does not disable IIS service and cause
the installation to be unsuccessful.

Understanding Client/Server Security Ports

Client/Server Security utilizes two types of ports:
• Server listening port (HTTP port): used to access the Trend Micro Security
Server. By default, Client/Server Security uses one of the following:
• IIS server default Web site – The same port number as your HTTP server’s
TCP port.
• IIS server virtual Web site – 8059
• Apache server – 8059
• Client listening port – A randomly generated port number through which the
client receives commands from the Trend Micro Security Server.
You can modify the server listening port during installation or after. You can modify
the client listening port only during installation.

WARNING! Many hacker and virus attacks use HTTP and are directed at ports 80 and/or
8080– commonly used in most organizations as the default Transmission
Control Protocol (TCP) ports for HTTP communications.

If your organization is currently using one of these ports as the HTTP port,
Trend Micro recommends using another port number.

Trend Micro Security Server Prescan

Before the master installer begins the installation process, it performs a prescan. This
prescan includes a virus scan and Damage Cleanup Services scan to help ensure the

4-7
CSM4SMB-v3-AG.book Page 8 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

target computer does not contain viruses, Trojans, or other potentially malicious
code.
The prescan targets the most vulnerable areas of the computer, which include the
following:
• the Boot area and boot directory (for boot viruses)
• the Windows folder
• the Program Files folder

Actions for Prescan Detections

If the Client Server Messaging Security setup program detects viruses, Trojans, or
other potentially malicious code, you can take the following actions:
• Clean – Cleans an infected file by removing the virus or malicious application.
Client/Server Security encrypts and renames the file if the file is uncleanable.
• Rename – Encrypts the file and changes the file extension to .VIR, VIR1, VIR2...
The file remains in the same location.
• Delete – Deletes the file.
• Pass – Does nothing to the file.

Tip: Trend Micro recommends cleaning or deleting infected files.

Other Installation Notes

Installing the Trend Micro Security Server does not require you to restart the
computer. After completing the installation, immediately configure the Trend Micro
Security Server, and then proceed to rolling out the Client/Server Security Agent
program. If using an IIS Web server, the setup program automatically stops and
restarts the IIS service during Web server installation.

WARNING! Make sure that you do not install the Web server on a computer that is running
applications that might lock IIS. This could prevent successful installation. See
your IIS documentation for more information.

CSM4SMB-v3-AG.book Page 9 Monday, April 23, 2007 10:40 AM

Client Server Messaging Security Installation Overview

Tip: Trend Micro highly recommends installing Client Server Messaging Security during
non-peak hours to minimize the effect on your network.

Installing Client Server Messaging Security

There are three methods for installing Client Server Messaging Security:
• Typical: provides a simple and easy solution for installing Client Server
Messaging Security using Trend Micro default values. This method is suitable for a
single small business using a single Trend Micro Security Server and up to ten
client desktops.
• Custom: provides flexibility in implementing your network security strategy. This
method is suitable if you have many computers and servers, or multiple Exchange
servers.
• Silent: performing a Silent installation creates a record file that you can use to
perform identical installations on other computers or networks.

Note: Close any running applications before installing Client Server Messaging Security. If
you install while other applications are running, the installation process may take
longer to complete.

Tip: You can preserve your client settings when you upgrade to this version of Client
Server Messaging Security or if you need to reinstall this version of the Client
Server Messaging Security. See Upgrading from a Previous Version on page
4-37 for instructions.

Note: If information from a previous MSA installation exists on the client, you will be
unable to install MSA successfully. Use the Windows Installer Cleanup Utility to
clean up remnants of the previous installation. To download the Windows Installer
Cleanup Utility, visit http://support.microsoft.com/kb/290301/en-us.

Note: If you upgrade the Client/Server Suite Server or Client Server Messaging Security
Server that is running of a Windows NT4 server, the upgrade process will be
interrupted and a warning message will appear. This happens as well if you upgrade
Client/Server Agent on a Windows 9x/NT client. If you continue with the upgrade, the
Client/Server Agent will be unable to report to the CSM Server.

Client Server Messaging Security 3.6 does not support upgrade under the following
conditions:
• Upgrade to Client Server Messaging Security 3.6 from OfficeScan Enterprise
Edition or ScanMail for Microsoft Exchange.
• Upgrade from one language to another.
• Client Server Security 3.6 will not upgrade Client/Server Security Agents running
on Windows 9x/ME/NT clients.
• Upgrade from Client/Server Suite 2.0 to Client Server Security 3.6
• Upgrade from Client/Server Suite 2.0 to Client Server Messaging Security 3.6

Tip: Upgrade from Client/Server/Messaging Suite 3.0/3.5 to Client Server

Messaging Security 3.6 You can preserve your client settings when you upgrade to
this version of Client Server Messaging Security or if you need to reinstall this
version.

Trend Micro recommends deleting all virus log files from the Trend Micro Security
Server before upgrading. If you want to preserve the virus log files, save them to
another location first.

To upgrade to this version of Client Server Messaging Security:

• Run the master installer program on the target computer. Upgrading is very similar
to performing a fresh install, but you will not be prompted to enter configuration
information, such as port numbers or proxy server information. Client Server
Messaging Security uses the same existing configuration information on the
computer (see Performing a Custom Installation on page 4-10 for instructions).

CSM4SMB-v3-AG.book Page 40 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

Tip: Before upgrading, check the size of your log files. If the log file is very large, Trend
Micro recommends that you run maintenance using your current version before you
upgrade. This will greatly reduce the amount of time required for upgrade.

• The quarantine and backup folders are retained during upgrading; however, you
will no longer be able to query the quarantined log or resend the quarantined items
from the previous version from the Security Dashboard of the upgraded version.
• If the previous version of Client Server Messaging Security used eManager, then
Client Server Messaging Security 3.6 retains the anti-spam logs from that version.

Upgrade Effect on Configurations

Upgrading to Client Server Messaging Security 3.6 has the following effects on old
configurations:
• End User Quarantine (EUQ).
The approved sender lists are maintained in the upgraded version.
• eManager.
Previous versions of Client Server Messaging Security used eManager anti-spam
rules to block email messages that matched specified keywords. In Client Server
Messaging Security 3.6, this function is provided by Content Filtering rules. The
anti-spam rule name from the previous version is imported to Client Server
Messaging Security 3.6. For detailed information about how Client Server
Messaging Security 3.6 upgrades anti-spam rules from eManager see Table 4-3.

CSM4SMB-v3-AG.book Page 4 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

• Migrating from a third-party antivirus installation to the current version of

Client/Server Security (see Migrating from Third-party Antivirus Applications on
page 5-17)

Note: Close any running applications on the client computers before installing the
Client/Server Security Agent. If you install while other applications are running, the
installation process may take longer to complete.

Performing a Fresh Install

Follow one of the procedures below if this is the first time you are installing the
Trend Micro Client Server Messaging Security Agent on the target computer.

Installing from the Internal Web Page

If you installed the Trend Micro Security Server to a computer running Windows
2000, Windows XP, or Windows Server 2003 with Internet Information Server (IIS)
5.0 or 6.0, or Apache 2.0.54, your client users can install the Client/Server Security
Agent from the internal Web server created during master setup.
This is a convenient way to deploy the Client/Server Security Agent. You only have
to instruct users to go to the internal Web page and download the Client/Server
Security Agent setup files.

Tip: You can use Vulnerability Scanner to see which clients have not followed the
instructions to install from the Security Dashboard (see Using Vulnerability
Scanner to Verify the Client Installation on page 5-21 for more information).

Users must have Microsoft Internet Explorer 5.5 or later with the security level set to
allow ActiveX controls to successfully download the Client/Server Security Agent
setup files. The instructions below are written from the client user perspective. Email
your users the following instructions to install the Client/Server Security Agent from
the internal Web server.
To install from the internal Web page:
1. Open an Internet Explorer window and type one of the following:

5-4
CSM4SMB-v3-AG.book Page 5 Monday, April 23, 2007 10:40 AM

Installing the Trend Micro Client Server Messaging Security Agent

• Trend Micro Security Server with SSL:

https://{Trend Micro Security
Server_name}:{port}/SMB/console/html/client

• Trend Micro Security Server without SSL:

3. Verify the installation by checking if the Client/Server Security Agent icon
appears in the Windows system tray.

Installing with Login Script Setup

Use Login Script Setup to automate the installation of the Client/Server Security
Agent on unprotected computers when they log on to the domain. Login Script Setup
adds a program called autopcc.exe to the server login script. The program
autopcc.exe performs the following functions:
• Determines the operating system of the unprotected computer and the
Client/Server Security Agent
• Updates the scan engine, virus pattern file, Damage Cleanup Services components,
cleanup file, and program files

Note: In order to enforce the use of login script installation method, client computers must
be listed in the Windows Active Directory of the server that is performing the
installation.

Installing the Trend Micro Client Server Messaging Security Agent

Note: When an unprotected computer logs on to the servers whose login scripts you
modified, autopcc.exe will automatically install the client to it.

Installing with Windows 2000/Server 2003 Scripts

If you already have an existing login script, Login Script Setup will append a
command that executes autopcc.exe; otherwise, it creates a batch file called
ofcscan.bat(which contains the command to run autopcc.exe).
Login Script Setup appends the following at the end of the script:
\\{Server_name}\ofcscan
where:
{Server_name} is the computer name or IP address of the computer where the
Trend Micro Security Server is installed
ofcscan is the shared name of the PCCSRV folder where the autopcc.exe is
located.
The Windows 2000 login script is on the Windows 2000 server (through a net logon
shared directory), under:
\\Windows 2000 server\system
drive\WINNT\SYSVOL\domain\scripts\ofcscan.bat
The Windows 2003 login script is on the Windows 2003 server (through a net logon
shared directory), under:
\\Windows 2003 server\system
drive\windir\sysvol\domain\scripts\ofcscan.bat

Installing with Client Packager

Client Packager can compress setup and update files into a self-extracting file to
simplify delivery via email, CD-ROM, or similar media. It also includes an email
function that can open your Microsoft™ Outlook address book and allow you to send
the package from within the Client Packager console.

CSM4SMB-v3-AG.book Page 8 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

When users receive the package, all they have to do is double-click the file to run the
setup program. Client/Server Security Agents installed using Client Packager report
to the server where Client Packager created the setup package. This tool is especially
useful when deploying the Client/Server Security Agent setup or update files to
clients in low-bandwidth remote offices.

Note: Client packager requires a minimum of 140MB free disk space on the client. Windows
Installer 2.0 is necessary for the client to run an MSI package.

Client Packager can create two types of self-extracting files:

• Executable – This common file type has an .exe extension

Note: In Windows Vista clients, the program must be executed with Administrator
rights (Run as Administrator).

• Microsoft Installer Package Format (MSI) – This file type conforms to the
Microsoft Windows Installer package specifications. For more information on
MSI, see the Microsoft Web site.

Tip: Trend Micro recommends using Active Directory to deploy an MSI package with
Computer Configuration instead of User Configuration. This helps ensure that the
MSI package will be installed regardless of which user logs on to the machine.

Note: Install Microsoft Outlook to use the Client Packager send mail option.

To create a package with the Client Packager GUI:

1. On the Trend Micro Security Server, open Windows Explorer.
2. Browse to \PCCSRV\Admin\Utility\ClientPackager
3. Double-click ClnPack.exe to run the tool. The Client Packager console opens.

Note: You must run the program from the Trend Micro Security Server only.

creating a Microsoft Windows Installer file. Use Client Packager to create a file with
an .msi extension. You can take advantage of Active Directory features by
automatically deploying the Client/Server Security Agent program to all your clients
simultaneously with the MSI file, rather than requiring each client to install
Client/Server Security Agent themselves.
For more information on MSI, see the Microsoft Web site (www.microsoft.com).
For instructions on creating an MSI file, see Installing with Client Packager on page
5-7).

on them. To determine if computers need protection, Vulnerability Scanner pings
ports that antivirus solutions normally use.
This section explains how to install the Client/Server Security Agent program with
Vulnerability Scanner. For instructions on how to use Vulnerability Scanner to detect
antivirus solutions, see the Administrative Tools section of the Administrator’s Guide
and the Trend Micro Security Server online help.

Note: You can use Vulnerability Scanner on machines running Windows 2000 or Server
2003; however, the machines cannot be running Terminal Server.

You cannot install the Client/Server Security Agent with Vulnerability Scanner if an
installation of the Trend Micro Security Server is present on the same machine.

Server, clients are automatically upgraded.

Migrating from Trend Micro Anti-Spyware

If you have Trend Micro Anti-Spyware (TMASY) on the network, take note of the
following:
• If you install the CSM server on the same server as the TMASY server, the CSM
server setup program will not remove or upgrade the TMASY server. You need to
manually remove the TMASY server before installing the CSM server on the same
machine.
• Removing the TMASY client before installing the Client/Server Security Agent
(CSA) is not required. The CSA setup program will automatically remove the
TMASY client when detected on the same client computer, and then install CSA.
• The anti-spyware settings for CSA and TMASY are different. After installing the
CSAs, you may need to configure the anti-spyware settings to make them the same
as your previous TMASY client settings. Refer to Table 5-2 for a comparison of
the CSA and TMASY anti-spyware settings.

Testing the Client Installation with the EICAR

Test Script
Trend Micro recommends testing your product and confirming that it works by using
the EICAR test script. EICAR, the European Institute for Computer Antivirus
Research, developed the test script as a safe way to confirm that antivirus software is
properly installed and configured. Visit the EICAR Web site for more information:
http://www.eicar.org

5-23
CSM4SMB-v3-AG.book Page 24 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

The EICAR test script is an inert text file with a .com extension. It is not a virus and
does not contain any fragments of viral code, but most antivirus software will react to
it as if it were a virus. Use it to simulate a virus incident and confirm that email
notifications, HTTP scanning, and virus logs work properly.

WARNING! Never use real viruses to test your antivirus installation.

To test the client installation with the EICAR test script:

1. Make sure Real-time scan is enabled on the client.
2. Copy the following string and paste it into Notepad or any plain text editor:
X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FI
LE!$H+H*
3. Save the file as EICAR.com to a temporary directory. Client/Server Security
Agent should immediately detect the file.
4. To test other computers on your network, attach the EICAR.com file to an email
message and send it to one of the computers.

Note: Trend Micro also recommends testing a zipped version of the EICAR file. Using
compression software, zip the test script and perform the steps above.

To test the client installation HTTP scanning capability:

• Download the EICAR.com test script from either of the following URLs:
http://www.trendmicro.com/vinfo/testfiles/
http://www.eicar.org/anti_virus_test_file.htm

Client/Server Security Agent should show that it detected the EICAR test file.

Removing the Client

There are two ways to remove the client – from the Security Dashboard and by

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

Using the Personal Firewall

Trend Micro Client Server Messaging Security for SMB has simplified the process of
configuring the Personal Firewall. In this version of Client Server Messaging
Security, there are two options to choose from when configuring the Personal
Firewall, simple mode and advanced mode. Simple mode enables the firewall with
the Trend Micro recommended default settings. Use advanced mode to customize the
Personal Firewall settings.

Personal Firewall Features

Personal Firewall helps protect Client Server Messaging Security Windows
2000/XP/Server 2003 clients from hacker attacks and network viruses by creating a
barrier between the client and the network.

Personal Firewall Defaults for Simple Mode

Personal Firewall provides default settings to give you a basis for initiating your
client firewall protection strategy. The defaults are meant to include common
conditions that may exist on your clients, such as the need to access the ScanMail for
Microsoft Exchange Web console.
TABLE 7-1. Personal Firewall Default Settings

Traffic Filtering
Personal Firewall filters all incoming and outgoing traffic, providing the ability to
block certain types of traffic based on the following criteria:
• Direction (incoming or outgoing)
• Protocol (TCP/UDP/ICMP)
• Destination ports
• Destination computer

Intrusion Detection System

Personal Firewall also includes an Intrusion Detection System (IDS). When enabled,
IDS can help identify patterns in network packets that may indicate an attack on the
client. Personal Firewall can help prevent the following well-known intrusions:
• Too Big Fragment
• Ping of Death
• Conflicted ARP
• SYN flood

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

• Overlapping Fragment
• Teardrop
• Tiny Fragment Attack
• Fragmented IGMP
• LAND attack

Exceptions
Exceptions are comprised of specific settings that allow or block different kinds of
traffic based on client port number(s) and IP address(es). You can configure a list of
exceptions. The exceptions in the list override the Security level settings.
Exception settings include the following:
• Action – Block or allow all traffic that meets the exception criteria
• Direction – Inbound or outbound network traffic to/from the client.
• Protocol – The type of traffic: TCP, UDP, ICMP.
• Port(s) – Ports on the client computer on which to perform the action.
• Computers – The computers on the network to which the above traffic criteria
apply.

Configuring Exceptions: An Example

During an outbreak, you may choose to block all client traffic, including the HTTP
port (port 80). However, if you still want to grant the blocked clients access to the
Internet, you can add the Web proxy server to the exception list.

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

The Messaging Security Agent

Client Server Messaging Security uses the Messaging Security Agent to gather
security information from Microsoft Exchange servers. For example, the Messaging
Security Agent reports spam detections or completion of component updates to the
Trend Micro Security Server. The information displays in the Security Dashboard
and the Trend Micro Security Server uses it generate logs and reports about the
security status of your Microsoft Exchange servers.
The Messaging Security Agent helps prevent email-borne viruses by scanning email
passing in and out of the Microsoft Exchange Mailbox Store as well as email that
passes between the Exchange Server and external destinations. In addition, the
Messaging Security Agent helps stop spam before it arrives at its destination.
Whenever the Messaging Security Agent backs up, quarantines, or archives an
infected file, it encrypts the file and stores it in the MSA storage folder, typically in
C:\Program Files\Trend Micro\Messaging Security
Client\storage\. This helps prevent users from opening the infected file and
spreading the virus to other files on the computer. If an infected file that has been
encrypted by MSA needs to be opened, use the Restore Encrypted Virus
(VSEncode.exe) tool. For more information on restoring files encrypted by MSA,
refer to Restore Encrypted Virus on page 15-8.

Note: Each detected threat generates one log entry/notification. This means that if
Messaging Security Agent detects multiple threats in a single email, it will generate
multiple log entries and notifications. There may also be instances when the same
threat is detected several times, especially if you are using cache mode in Outlook
2003. When cache mode is enabled, the same threat may be detected both in the
transport queue folder and Sent Items folder, or in the Outbox folder.

Configurable Options for Exchange Server Groups

The following items can be accessed by clicking Configure from the Security
Settings screen:
• Antivirus – Configure real-time scan options for all members of the group.
• Anti-spam – Set spam detection level, configure approved/blocked senders list,
and set actions for spam.

Real-Time Virus Scanning on Exchange

Servers
The Messaging Security Agent guards all known virus entry points with real-time
scanning of all incoming messages, SMTP messages, documents posted on public
folders, and files replicated from other Microsoft Exchange servers.
The Messaging Security Agent scans the following in real time:
• All incoming and outgoing email messages
• SMTP messages arriving at Exchange from the Internet
• Public-folder postings
• All server-to-server replications

8-4
CSM4SMB-v3-AG.book Page 5 Monday, April 23, 2007 10:40 AM

Protecting Your Microsoft Exchange Servers

Note: The speed of real-time scanning depends on its settings. You can increase the
performance of real-time scans by specifying certain file types that are
vulnerable to viruses or by limiting the maximum number of compression layers
to scan.

The following are the basic steps for configuring anti-virus. The Messaging Security
Agent provides identical options to configure Real-time, Manual, and Scheduled virus scans.

Refer to Scanning Exchange Servers for Viruses, Malware, and Other Threats on
page 10-5 for more information about configuring Manual and Scheduled scans.
Step 1: Select the Target tab and set the files to include in your scan.
The target for a scan is the file(s) or content contained in email messages. The
Messaging Security Agent usually scans the files according to the true file type
unless you configure the Messaging Security Agent to scan specific file types.
SeeFile Types Eligible for Scanning on page 8-5.
Step 2: Select the Action tab to set the actions that the Messaging Security Agent
takes when it detects a virus or other threat in the files you specified.
You can select ActiveAction to use the Trend Micro recommended actions or
customize your actions according to the type of threat detected.
When the Messaging Security Agent (MSA) detects a threat in an email, it can send
notifications to the email sender and/or recipients. From this screen, you can choose
who MSA should notify when it detects a threat in an email. See Sending
Notifications as a Course of Action on Detected Email Threats on page 8-12
Step 3: Select the Preferences > Notifications menu item to set who is notified
when virus events occur and how they receive notification. See Configuring Event
Notifications on page 13-2.

File Types Eligible for Scanning

By default, the Messaging Security Agent scans all scannable outgoing, incoming
and stored messages in your Exchange environment. Scanning all files provides the
maximum security possible. However, scanning every message requires a lot of time
and resources and might be redundant in some situations. Therefore, you might want
to limit the amount of files the Messaging Security Agent includes in the scan. Table

8-5
CSM4SMB-v3-AG.book Page 6 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

describes the methods that the Messaging Security Agent can use to determine which
files to scan.

TABLE 8-2. Types of Target Files

Target type Description

All scannable files Messaging Security Agent scans for viruses, worms,
Trojans, and other malicious code in all file attachments -
except unscannable files. Unscannable files are
encrypted or password protected files.

See About Scannable Files on page 8-6 for more

information about files that Messaging Security Agent
does not scan.

IntelliScan IntelliScan uses Trend Micro recommended settings to

perform an efficient scan

See True File Type on page B-5 for more information

about how the Messaging Security Agent identifies true
file types.

Specific file type The Messaging Security Agent scans only the file types
you specify. File type is determined by file extension
name. For ease of use, Trend Micro has grouped file
extension types in functional groups. Select file types by
group or drill-down to select individual file extension
types.

For some files, such as very large attachments and compressed files, you can set
restrictions on how the Messaging Security Agent scans (See Set Exclusions for
Large Attachments and Compressed Files on page 8-7).

About Scannable Files

When you select All scannable files, the Messaging Security Agent scans all files
except files that are encrypted, password protected, or those it judges to be
unscannable. To protect yourself from threats contained in unscannable files,
configure the Messaging Security Agent to execute a special action against
unscannable files.See About the Messaging Security Agent Scan Actions on page 8-8

8-6
CSM4SMB-v3-AG.book Page 7 Monday, April 23, 2007 10:40 AM

Protecting Your Microsoft Exchange Servers

Files That Are Not Scanned

The scan engine does not scan some files that are unlikely to harbor viruses, for
example, .gif files. The scan engine determines whether it is necessary to scan a file
by examining the file header—if the scan engine determines that the file content
matches a type that does not harbor viruses, then it does not examine the content of
the file body.

Set Exclusions for Large Attachments and Compressed Files

You can configure how the Messaging Security Agent scans email messages that
have a large message body or contain very large attachments, and/or compressed
files. Use the options from Anti-virus > Scanning restrictions to set limits for the
Messaging Security Agent. The Messaging Security Agent will not scan files that
exceed your limits.

Note: A compression layer is added each time a file is compressed. That is, if a file is
compressed and then compressed again, it has two layers of compression.

Tip: Trend Micro recommends using Exclusions to set scanning restrictions to protect
against Denial of Service attacks (DoS). DoS attacks cause a loss of service, namely
a network connection. Typically, DoS attacks negatively affect network bandwidth or
overload computer resources such as memory.

See Screening Out Spam on page 8-17 for more information about how the
Messaging Security Agent processes compressed files.

How the Messaging Security Agent Scans Emails

The Messaging Security Agent (MSA) first scans emails for spam and then scans for
content filtering violations. It next scans for attachments that are in violation of
administrator defined rules. Finally the MSA scans for viruses.
The MSA completes the following scanning processes when scanning emails
1. Scans for spam (Anti-spam)
a. Compares the email to the administrator’s approved/blocked senders list
b. Checks for phishing occurrences

8-7
CSM4SMB-v3-AG.book Page 8 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

c. Compares the email with the Trend Micro supplied exception list
d. Applies heuristic scanning rules
e. Compares the email with the Spam signature database
2. Scans for content filtering rule violations
3. Scans for attachments that exceed user defined parameters
4. Scans for viruses (Antivirus)

About the Messaging Security Agent Scan Actions

When the Messaging Security Agent detects a file that matches your scanning
configurations, it executes an action to protect your Exchange environment. The type
of action it executes depends on the type of scan it is performing (real-time, manual,
or scheduled) and the type of actions you have configured for the Messaging Security
Agent to take against the detected threat.
You can configure the Messaging Security Agent to execute one of the following
basic types of action:
ActiveAction: Select ActiveAction to have the Messaging Security Agent execute
actions recommended by Trend Micro. SeeTrend Micro ActiveAction on page B-4.
Customized Action: You can configure the Messaging Security Agent to take
customized actions according to the type of threat presented by viruses, Trojans,
worms, packers, and other threats. SeeUsing Customized Actions on page 8-9.
Advanced Options: Use the Advanced Options to:
• Set the action the Messaging Security Agent takes against unscannable or excluded
files.
• Enable macro scanning and set the macro scanning method.
• Set up the backup directory to where the Messaging Security Agent moves backed
up files.
• Type the text that the Messaging Security Agent uses when it replaces text/file.

Types of Security Threats

The types of computer security threats are constantly changing. The Messaging
Security Agent is designed to counter all prevalent attacks. Table 8-3 introduces
some common types of security threats that the Messaging Security Agent can
protect your Exchange environment against.

TABLE 8-3. Types of Security Threats

Attack type Description

A virus is a malicious code that infects files so that it can

replicate and cause damage to your computer. In
Viruses messaging environments, infected files are often spread
through email attachments. When infected files are
executed, viruses replicate and may damage your
computer’s files or operations.

A Trojan horse program is a program that performs some

unexpected or unauthorized - usually malicious – actions.
Trojans, like regular programs, must be run to be
Trojans effective. Frequently Trojan horse programs are installed
and/or run when users launch a seemingly harmless
application by clicking on an email attachment.

A computer worm is a self-contained program (or set of

Worms programs) that can spread functional copies of itself or its
segments to other computer systems. Worms often use
email and applications to propagate.

A compressed and/or encrypted Windows or Linux

executable program, often a Trojan. Compressing
Packers executables makes them more difficult for Antivirus
products to detect.

The Messaging Security Agent detects some malicious

code that is difficult to categorize, but poses a significant
Other threats threat to Exchange. This category is useful when you
want the Messaging Security Agent to perform an action
against a previously unknown threat type.

Using Customized Actions

You can configure the Messaging Security Agent to take actions according to the
type of threat presented by viruses, Trojans, and worms. If you use customized

8-9
CSM4SMB-v3-AG.book Page 10 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

actions, you can set an action for each type of threat. The Messaging Security Agent
executes the action you set when it detects a threat of the matching type.

TABLE 8-4. Messaging Security Agent Customized Actions

Action Description

Clean Removes malicious code from infected message bodies and

attachments. The remaining email message text, any uninfected files,
and the cleaned files are delivered to the intended recipient(s). Trend
Micro recommends you use the default scan action clean for viruses.

Under some conditions, the Messaging Security Agent cannot clean a

file. SeeAbout Uncleanable Files on page 8-11.

During a manual or scheduled scan, the Messaging Security Agent

updates the Information Store and replaces the file with the cleaned one.

Replace with The Messaging Security Agent deletes the infected content and replaces
text/file it with text or a file. The email message is delivered to the intended
recipient, but the text replacement informs them that the original content
was infected and was replaced.

Quarantine Moves the email message to a restricted access folder, removing it as a

entire message security risk to the Exchange environment. The original recipient will not
receive the message. This option is not available in manual and
scheduled scanning.

SeeSetting up the Quarantine Folder on page 8-40 for more

information about the quarantine folder.

Delete entire During real-time scanning, the Messaging Security Agent deletes the
message entire email message. The original recipient will not receive the
message. This option is not available in manual or scheduled scanning.

The delete action in Client Server Messaging Security 3.6 differs from
that of previous versions of Messaging Security such as ScanMail 6.21.
ScanMail 6.21 used the action delete to remove the contents of a
message and replace it with a warning text. The delete entire message
in Client Server Messaging Security 3.6 will completely delete messages
and will not send the message on to the original recipient.

Protecting Your Microsoft Exchange Servers

TABLE 8-4. Messaging Security Agent Customized Actions

Action Description

Pass Records virus infection of malicious files in the Virus logs, but takes no
action.

Note: For Excluded files or Encrypted and Password protected

files, when you configure the action to Pass, files or
message body over the specified scanning restrictions, or
encrypted files and files that are protected by passwords
are passed and the event is not logged

Mass-mailing Behavior
Email-aware viruses, like the infamous Melissa, Loveletter, AnnaKournikova and
others, have the ability to spread through email by automating the infected
computer's email client. Mass-mailing behavior describes a situation when an
infection spreads rapidly between clients and servers in an Exchange environment.
Trend Micro designed the scan engine to detect behaviors that mass-mailing attacks
usually exhibit. The behaviors are recorded in the Virus Pattern file that is updated
using the TrendLabs™ ActiveUpdate Servers.
Enable the Messaging Security Agent to take action against these attacks whenever it
detects a mass-mailing behavior. The action set for mass-mailing behavior takes
precedence over all other actions. The default action against mass-mailing attacks is
Delete entire message.

About Uncleanable Files

When the Messaging Security Agent cannot successfully clean a file, it labels the file
"uncleanable" and performs the user-configured action for uncleanable files. The
default action is Delete entire message. The Messaging Security Agent records all
virus events and associated courses of action in the log file.
Some common reasons why the Messaging Security Agent cannot perform the clean
action are as follows:
• The file contains a Trojan, worm, or other malicious code. To stop an executable
from executing, the Messaging Security Agent must completely remove it.

8-11
CSM4SMB-v3-AG.book Page 12 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

• The Messaging Security Agent does not support the compression format used to
compress the file. The scan engine only cleans files compressed using pkzip and
only when the infection is in the first layer of compression.
For example, consider a compressed file titled “EuropeanBusinessTrip.zip” which
contains the following
FIGURE 8-1. Compression Layers Explained

EuropeanBusinessTrip.zip is 3
compression layers deep.

Only files in the first compression

layer, shown in red font, such as
"Airline ticket" and "Sightseeing on
the weekend" can be cleaned.

• An unexpected problem prevents the Messaging Security Agent from cleaning,

such as:
• The temp directory that acts as a repository for files requiring cleaning is full
• The file is locked or is currently executing
• The file is corrupted
• The file is password protected
• The file is located in the Windows Recycle Bin, Windows Temp folder, or
Internet Explorer temporary folder

Sending Notifications as a Course of Action on Detected Email

Threats
When the Messaging Security Agent (MSA) detects a threat in an email, it can send
notifications to the email sender and/or recipients. From the Action tab area of the

8-12
CSM4SMB-v3-AG.book Page 13 Monday, April 23, 2007 10:40 AM

Protecting Your Microsoft Exchange Servers

Antivirus/Anti-spyware screen, you can configure MSA to send notifications to all

senders and/or recipients or to just internal senders and/or recipients. You can also
configure MSA to not send notifications when it detects spoofing mails.

Backing Up Files Before Taking Action

You can set the Messaging Security Agent to backup a file to the Backup folder
before taking action on it. This is a safety precaution designed to protect the original
file from damage.

Tip: Trend Micro recommends quickly deleting backed up files once you have determined
that the original file was not damaged and that it is usable. If the file becomes
damaged or unusable, send it to Trend Micro for further analysis. (Even if the
Messaging Security Agent has completely cleaned and removed the virus itself, some
viruses damage the original file code beyond repair.)

To specify the location of the Backup folder:

1. From the Antivirus screen, click the Action tab.
2. Click the plus icon to expand the Backup Directory panel.
3. Type the directory path for your backup folder in the space provided.
4. Click Save.

Do not clean infected compressed files to improve performance

Select this option to improve the Messaging Security Agent performance. When the
Messaging Security Agent detects a security threat in a compressed file, it will not
clean the file. Instead, it processes the files as if they were uncleanable.

Using Advanced Scanning Options

Use the Advanced Options to set how the Messaging Security Agent handles
macros, unscannable files, and excluded files. You can also set up the backup and
quarantine folders and customize the replacement file/text used when the Messaging
Security Agent replaces an infected attachment.

8-13
CSM4SMB-v3-AG.book Page 14 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

Using Advanced Macro Scanning

The Messaging Security Agent uses the virus pattern file to identify known malicious
macro codes during regular virus scanning. The Messaging Security Agent takes
action against malicious macro code depending on the action that you configure from
the Anti-virus screen. Use Advanced macro scanning to gain additional protection
against malicious macro code.
Advanced macro scanning supplements regular virus scanning. It uses heuristic
scanning to detect macro viruses or simply strips all detected macro codes. Heuristic
scanning is an evaluative method of detecting viruses that uses pattern recognition
and rules-based technologies to search for malicious macro code. This method excels
at detecting undiscovered viruses and threats that do not have a known virus
signature. When a malicious macro code is detected using heuristic scanning, the
Messaging Security Agent takes action against the malicious code based on the
action that you configured from the Antivirus screen. When you select Delete all
macros detected by advanced macro scanning, the Messaging Security Agent
strips all macro code from the scanned files.

Enabling and Disabling Scans

You can enable or disable virus scanning for real-time or scheduled scans.
Real-time scanning is persistent and ongoing. When you enable real-time scanning,
the Messaging Security Agent starts to scan all incoming and outgoing messages
immediately. Real-time scanning consists of four filters: Antivirus, Content Filtering,
Attachment Blocking, and Anti-spam. You can enable and disable each filter
separately. When all of the filters are disabled, no real-time scanning can occur.
Disabling a real-time scanning filter does not disable or change your scan
configurations.

WARNING! If you disable real-time scanning, you are vulnerable to infected files entering the
Exchange environment while the scan is disabled.

Protecting Your Microsoft Exchange Servers

About Blocking Attachments

Attachment blocking prevents email messages containing suspect attachments from
being delivered to the Exchange Information Store. You can configure the Messaging
Security Agent to block attachments according to the attachment type or attachment
name and then replace, quarantine, or delete all the messages that have attachments
that match your configuration.
Blocking can occur during real-time, manual, and scheduled scanning, but the delete
and quarantine actions are not available for manual and scheduled scans. You can
enable or disable attachment blocking.
The extension of an attachment identifies the file type, for example .txt, .exe, or .dll.
However, the Messaging Security Agent examines the file header rather than the file
name to ascertain the actual file type. Many viruses are closely associated with
certain types of files. By configuring the Messaging Security Agent to block
according to file type, you can decrease the security risk to your Exchange servers
from those types of files. Similarly, specific attacks are often associated with a
specific file name.

Tip: Using blocking is an effective way to control virus outbreaks. You can temporarily
quarantine all high-risk file types or those with a specific name associated with a
known virus. Later, when you have more time, you can examine the quarantine
folder and take action against infected files.

CSM4SMB-v3-AG.book Page 16 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

Selecting Blocking Targets

Block attachments with two general strategies: either block all attachments and then
exclude specified attachments or specify all the attachments to block.
• All attachments
The Messaging Security Agent can block all email messages that contain
attachments. However, this type of scan requires a lot of processing. Refine this
type of scan by selecting attachment types or names to exclude.
• Specified attachments
When you select this type of scan, the Messaging Security Agent only scans for
email messages containing attachments that you identify. This type of scan can be
very exclusive and is ideal for detecting email messages containing attachments
that you suspect contain threats. This scan runs very quickly when you specify a
relatively small amount of attachment names or types.
You can block attachments according to:
• Specific name
By default, the Messaging Security Agent examines the file header rather than the
file name to ascertain the actual file type. When you set Attachment Blocking to
scan for specific names, the Messaging Security Agent will detect attachment types
according to the name they were given.
• Attachment type
The Messaging Security Agent examines the file header rather than the file name
to ascertain the actual file type.

Protecting Your Microsoft Exchange Servers

Attachment Blocking Actions

You can configure the Messaging Security Agent to take action against email
messages containing detected threats. The following table lists the actions the
Messaging Security Agent can take.

TABLE 8-5. Attachment Blocking Actions

Action Description

Replace with The Messaging Security Agent deletes the attachment and replaces
text/file it with a text file. The email message is delivered to the intended
recipient, but the text replacement informs them that the original
content was infected and was replaced.

Quarantine Moves the email message that contains the attachment to a

restricted access folder, removing it as a security risk to the
Exchange environment. This action is not available for manual or
scheduled scans.

Delete entire During real-time scanning, the Messaging Security Agent deletes
message the entire email message. This option is not available in manual or
scheduled scanning.

Screening Out Spam

The Messaging Security Agent uses the Trend Micro spam engine and spam pattern
file to screen each email message for spam before delivering them to the Information
Store. The Exchange server will not process rejected spam mail and the messages do
not end up in your client’s mailboxes.
The Messaging Security Agent performs one of the following actions on detected
spam during real-time scanning:
• Quarantines spam messages to a server-side spam folder
• Quarantines spam messages to user’s spam folder
• Deletes the spam message
• Tags and delivers messages as spam

8-17
CSM4SMB-v3-AG.book Page 18 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

Note: Microsoft Outlook may automatically filter and send messages that MSA detected as
spam to its Junk Mail folder.

Approved and Blocked Sender Lists

Administrators can set up Approved and Blocked senders lists for the Messaging
Security Agent. The Messaging Security Agent does not classify addresses from the
Approved senders list as spam (unless it detects a phishing incident), nor does it filter
messages from this list as spam. The Messaging Security Agent filters addresses
from Blocked senders lists and always classifies them as spam with the action
depending on the rule set by the administrator.

Note: The Exchange administrator maintains a separate Approved and Blocked Senders list
for the Exchange server. If an end-user creates an approved sender, but that sender is
on the administrator's Blocked Senders list, the Messaging Security Agent detects
messages from that blocked sender as spam and takes action against those messages.

Note: When importing an Approved and Blocked Senders list, make sure that the text file is
encoded in ANSI format to avoid compatibility issues. If you import the list in
Unicode format, you will unable to import the list successfully.

The Spam Filter

Administrators can set the spam detection rate to screen out spam. The detection
level determines how tolerant the Messaging Security Agent will be towards suspect
email messages. A high detection level quarantines most email as spam, but it might
also falsely identify and quarantine legitimate email messages as spam, creating
"false positive" spam mail. A low detection level does not rigorously screen email
messages, but does not create many false positive spam messages.
SeeSetting the Spam Detection Rate on page 8-21.

Seven Spam Categories

The Messaging Security Agent screens spam according to seven categories and
allows administrators to specify a detection level for each category:

8-18
CSM4SMB-v3-AG.book Page 19 Monday, April 23, 2007 10:40 AM

Protecting Your Microsoft Exchange Servers

• Adult
• Commercial
• Financial
• Spiritual
• Health
• Racial
• Others
Example: If an administrator’s clients work in the banking field, the administrator
might decide to set a high sensitivity level for the "sexual" category - messages in
this category are very likely to be classified as spam. However, it might be more
difficult to filter "commercial" type messages. Therefore, the administrator can set a
low sensitivity level for email messages in the "commercial" category.

Using Approved and Blocked Senders List

An Approved Senders list is a list of trusted email addresses. The Messaging Security
Agent does not filter messages arriving from these addresses for spam - except when
Detect Phishing incidents is enabled. When you have enabled Detect Phishing
incidents, and the Messaging Security Agent detects a phishing incident in an email,
then that email message will not be delivered even when it belongs to an approved
sender list. A Blocked Senders list is a list of suspect email addresses. The Messaging
Security Agent always categorizes email messages from blocked senders as spam
and takes the appropriate action.
There are two Approved Senders lists: one for the Exchange administrator and one
for the end-users.
• The Exchange administrator uses the Anti-spam screen to manage his or her lists.
The Exchange administrator’s Approved Senders list and Blocked Senders list
control how the Messaging Security Agent handles email messages bound for the
Exchange server.
• The end-user manages the Spam Folder that is created for them during installation.
The end-users’ lists only affect the messages bound for the server-side mailbox
store for each individual end-user.
For example: The sender "user@singles.com" is on the administrator’s Blocked
senders list, but the end-user has added that address to his Approved senders list.

8-19
CSM4SMB-v3-AG.book Page 20 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

Messages from that sender arrive at Exchange and the Messaging Security Agent
detects them as spam and takes action against them. If the Messaging Security Agent
takes the Quarantine message to user’s spam folder action, it will attempt to deliver
the message to the end user’s Spam folder, but the message will be redirected to the
end user’s inbox instead because the end user has approved that sender.

Note: When you are using Outlook, there is a rule size limit for the amount and size of
addresses on the list. To prevent a system error, the Messaging Security Agent
limits the amount of addresses that an end user can include in his or her approved
sender list (this limit is calculated according to the length and the number of email
addresses)

The Messaging Security Agent supports wildcard matching for Approved and
Blocked Senders lists. It uses the asterisk (*) as the wildcard character.

The Messaging Security Agent does not support the wildcard match on the username
part. However, if you type a pattern such as “*@trend.com”, the Messaging Security
Agent still treats it as “@trend.com”. This feature applies to user-defined Approved
Senders and Blocked Senders.

Setting the Spam Detection Rate

The spam engine makes use of spam signatures and heuristic rules to screen email
messages. It scans email messages and assigns a spam score to each one based on
how closely it matches the rules and patterns from the pattern file. The Messaging
Security Agent compares the spam score to the user-defined spam detection level.
When the spam score exceeds the detection level, the Messaging Security Agent
takes action against the spam.
For example: Spammers often use many exclamation marks, or more than one
consecutive exclamation mark(!!!!) in their email messages. When the Messaging
Security Agent detects a message that uses exclamation marks in this way, it
increases the spam score for that email message.
Select one of these options for your spam detection:
• High
This is the most rigorous level of spam detection. The Messaging Security Agent
monitors all email messages for suspicious files or text, but there is greater chance

8-21
CSM4SMB-v3-AG.book Page 22 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

of false positives. False positives are those emails that the Messaging Security
Agent filters as spam when they are actually legitimate emails.
• Medium
This is the default setting. The Messaging Security Agent monitors at a high level
of spam detection with a moderate chance of filtering false positives.
• Low
This is most lenient level of spam detection. The Messaging Security Agent will
only filter the most obvious and common spam messages, but there is a very low
chance that it will filter false positives.

Note: If a significant volume of spam is not caught by the spam engine, download the Trend
Micro Anti-Spam Pilot for advanced protection against spam. For more information,
visit
http://www.trendmicro.com/en/products/desktop/anti-spam/evaluate/overview.htm.

Detecting and Taking Action Against Phish

A Phish is an email message that falsely claims to be from an established or
legitimate enterprise. The message encourages recipients to click on a link that will
redirect their browsers to a fraudulent Web site where the user is asked to update
personal information such as passwords, social security numbers, and credit card
numbers in an attempt to trick a recipient into providing private information that will
be used for identity theft.
When the Messaging Security Agent detects a Phish message, it can take the
following actions:
• Quarantine message to a server-side spam folder
The Messaging Security Agent sends the entire message to the CSM Server for
quarantine.
• Delete entire message
The Messaging Security Agent deletes the entire message and Exchange does not
deliver it.
• Tag and deliver

8-22
CSM4SMB-v3-AG.book Page 23 Monday, April 23, 2007 10:40 AM

Protecting Your Microsoft Exchange Servers

The Messaging Security Agent adds a tag to the header information of the email
message that identifies it as phish and then delivers it to the intended recipient.

Filtering Undesirable Content

Content Filtering evaluates inbound and outbound messages on the basis of
user-defined rules. Each rule contains a list of keywords and phrases. Content
filtering evaluates the header and/or content of messages by comparing the messages
with the list of keywords. When the content filter finds a word that matches a
keyword it can take action to prevent the undesirable content from being delivered to
Exchange clients. The Messaging Security Agent can send notifications whenever it
takes an action against undesirable content.
The content filter provides a means for the administrator to evaluate and control the
delivery of email on the basis of the message text itself. It can be used to monitor
inbound and outbound messages to check for the existence of harassing, offensive, or
otherwise objectionable message content. The content filter also provides a synonym
checking feature which allows you to extend the reach of your policies. You can, for
example, create rules to check for:
• Sexually harassing language
• Racist language
• Spam embedded in the body of an email message

Viewing Content Filtering Rules

The Messaging Security Agent (MSA) displays all the content filtering rules in the
Content Filtering screen. This screen shows summary information about the rules
including:
• Action: MSA takes this action when it detects undesirable content
• Order: MSA applies each filter in succession according to the order shown on this
page.
• Enabled: During real-time scan, manual scan, or schedule scan, you can enable or
disable all content filtering or each individual content filter rule. The icons on the
Content Filtering screen show the status of the content filtering rule. Click on the
icon to toggle between enabled and disabled.

Changing the Rule Order

MSA applies the content filtering rules to email messages according to the order
shown in the Content Filtering screen. You configure the order in which the rules are
applied. MSA filters all email messages according to each rule until a content
violation triggers an action that prevents further scanning (such as delete or
quarantine). You can change the order of these rules to optimize content filtering.
To change the order of the content filtering rules:
1. Select a check box that corresponds to the rule for which you want to change the
order.
2. Click Reorder. A box appears around the order number for the rule.
3. Type a new order number in the box. The rule order number will change to the
number that you type and all the other rule order numbers will change
accordingly.
For example: If you select rule number 5 and change it to rule number 3, then
rule numbers 1 and 2 will remain the same, and rule numbers 3 and higher will
increase by one number.

About Filtering Keywords

Keywords are not strictly words. They can be any of the following:
• Numbers
• Typographical characters
• Short phrases

CSM4SMB-v3-AG.book Page 30 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

• Words or phrases connected by logical operators

• Words or phrases that use regular expressions

Using Keywords Effectively

MSA offers simple and powerful features to create highly specific filters. Consider
the following, when creating your Content Filtering rules:
• By default, MSA searches for exact matches of keywords. Use regular expressions
to set MSA to search for partial matches of keywords.
• MSA analyzes multiple keywords on one line differently than multiple keywords
when each word occupies a single line. See Table 8-8 for more information about
using keywords on multiple lines.
• You can also set MSA to search for synonyms of the actual keywords.

TABLE 8-7. How to Use Keywords

Situation Example Match / non-match

Two words on bare sexy Matches:

Formatting Keywords That Use Operators

When typing a keyword or phrase that includes an operator, follow the format in the
example below:
Example: .WILD. valu*

Note: The operator has a dot immediately preceding and following. There is a space between
the final dot and the keyword.

For example: apple OR orange. MSA
searches for either apple or orange. If For example:
content contains either, then there is "apple .OR. orange"
a match.

AND MSA searches for all of the keywords Type ".AND." between all
separated by AND the words you want to

For example: .NOT. juice. MSA For example: ".NOT. juice"

searches for content that does not
contain juice. If the message has
"orange soda", there is a match, but if
it contains "orange juice", there is no
match.

Using Regular Expressions

Regular expressions are used to perform string matching. See the following tables for
some common examples of regular expressions. To specify a regular expression, add
a ".REG." operator before that pattern.

Note: Regular expressions are a powerful string matching tool. For this reason, Trend Micro
recommends that administrators who choose to use regular expressions be familiar
and comfortable with regular expression syntax. Poorly written regular expressions
can have a dramatic negative performance impact. Trend Micro’s recommendation is
to start with simple regular expressions that do not use complex syntax. When
introducing new rules, use the archive action and observe how MSA manages
messages using your rule. When you are confident that the rule has no unexpected
consequences, you can change your action.

To create a rule that filters messages that match all conditions

defined:
Step 1: Select the type of content rule
1. From the Content Filtering page, click Add.
2. Select Filter messages that match all conditions defined.
3. Click Next.
Step 2: Name your rule and select the message part to filter for keywords
1. Type the name of your rule in the Rule name space.
2. Set the part of the message that MSA filters. MSA can filter messages according
to:
• Message header
Type a keyword in the From, To, CC, and/or Subject field to have MSA take
action against email messages that contain matching keywords in the
corresponding fields. Separate multiple keywords with a semi-colon (;).
• Attached files
Type a name in the Attachment file name field. MSA takes action against
messages that have attachments with the name you specify. Separate multiple
keywords with a semi-colon (;).

About the Quarantine Folder

When the Messaging Security Agent quarantines a message, the message is sent to a
designated quarantine folder.
When the Messaging Security Agent quarantines an email message, it logs the event.
You can query the quarantine database to gather information about quarantined
messages. See Querying the Quarantine Folder on page 8-41.
You can use Quarantine to:
• Reduce the chance of important messages being deleted, if they are erroneously
detected by aggressive filters
• Review messages that trigger content filters to determine the severity of the policy
infraction
• For disciplinary purposes, maintain evidence of an employee’s continued misuse of
your company’s messaging system

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

Note: Do not confuse the quarantine folder with the end user’s spam folder. An administrator
sets up the quarantine folder after installing the Messaging Security Agent. The
quarantine folder is a file-based folder. The Messaging Security Agent creates the end
user’s spam folder during installation. The end user’s spam folder is located in the
Information Store for each user's mailbox. Whenever the Messaging Security Agent
does a quarantine action on an email message, it sends the message to the quarantine
folder. The end user’s spam folder only receives email messages resulting from an
anti-spam quarantine action.

Setting up the Quarantine Folder

The Messaging Security Agent quarantines email messages according to your
configured actions. You can create one quarantine folder for each action. The
Messaging Security Agent can quarantine email messages as the result of the
following:
• Antivirus
The Messaging Security Agent quarantines email messages containing viruses,
worms, Trojans, and other malicious threats. Set the quarantine folder from
Antivirus > Action > Quarantine Directory.
• Anti-spam
The Messaging Security Agent quarantines spam and phishing email. Set the
quarantine folder from Anti-spam > Action > server-side spam folder.
• Attachment blocking
The Messaging Security Agent quarantines email messages containing
questionable attachments. Set the quarantine folder from Attachment Blocking >
Action > Quarantine Directory.
• Content filtering
The Messaging Security Agent quarantines email messages containing undesirable
content. Set the quarantine folder from Content Filtering > Select rule > Action >
Quarantine Directory.
To set up the Quarantine Directory
1. Click Security Settings.
2. Choose the Exchange servers where you want to set up quarantine directories.

Protecting Your Microsoft Exchange Servers

3. Click Configure. The Antivirus screen opens for the Exchange Server.
4. Click Quarantine > Directory.
5. Type the directory path for the quarantine directory in the space provided.
6. Click Save.

Viewing the Quarantine Folder

You can view the quarantine folder to determine whether messages are safe. When
you think a message is safe, delete the entire message or resend the complete email
messages to the original recipients.

WARNING! The quarantine folder contains email messages that have a high-risk of being
infected. Be cautious when handling email messages from the quarantine folder
so that you do not accidentally infect your computer.

Querying the Quarantine Folder

To view information about quarantined messages, you must make a quarantine query.
Use the Quarantine > Query to set up and run your queries.

Resending Quarantined Messages

You can resend messages that you consider safe to the original recipient. When you
resend messages, the entire email message is resent.

Note: If you resend a quarantined message that was originally sent using Microsoft Outlook,
the recipient may receive multiple copies of the same message. This may occur
because VSAPI strips each message that it scans into several sections.

Deleting Quarantined Messages

The Messaging Security Agent provides a Quarantine Maintenance screen where you
can configure how long to keep the quarantined messages and schedule regular
maintenance.

CSM4SMB-v3-AG.book Page 42 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

Managing the End User Quarantine Tool

During installation, the Messaging Security Agent adds a folder, Spam Mail, to the
server-side mailbox of each end user. When spam messages arrive, the system
quarantines them in this folder according to spam filter rules predefined by the
Messaging Security Agent. End users can view this spam folder to open, read, or
delete the suspect email messages.
See Setting up the Spam Folder on page 8-43
End users can open email messages quarantined in the spam folder. When they open
one of these messages, two buttons appear on the actual email message: Approved
Sender and View Approved Sender List. When they click Approved Sender, the
Messaging Security Agent moves the message from that sender to their inbox, adds
the address of the message to their personal Approved Sender List. Clicking View
Approved Sender opens another screen that allows the end user to view and modify
their list of approved senders by SMTP email address or domain. When the Exchange
server receives messages from the addresses on the end user’s approved sender list, it
delivers them to the end user’s inbox, regardless of the header or content of the
message.

Note: Client Server Messaging Security also provides administrators with an Approved
Senders and Blocked Senders list. The Messaging Security Agent applies the
administrator’s approved senders and blocked senders before considering the end user
list.

End User Quarantine Housekeeping Feature

The Messaging Security Agent housekeeping feature performs programmed tasks
every 24 hours at the default time of 2:30 AM. It performs the following duties:
• Auto-deletes expired spam messages
• Recreates the spam folder when it has been deleted
• Creates spam folders for newly created mail accounts
• Maintains email message rules.
The housekeeping feature is an integral part of the Messaging Security Agent and
requires no configuration.

The Outbreak Defense Strategy

The Outbreak Defense Strategy is based on the idea that outbreaks have a lifecycle.
They (the infection) start slow, infecting only a few clients initially. As time goes on,
the few infected clients unknowingly pass the infection to other clients. At this point,
the infection has spread throughout the network, or if the affect of the infection was
noticeable, the client users and administrator realized they have a problem and take
action. Slowly, the outbreak subsides. Maybe the infection gets chance to flare up
again as unaware and unprotected client users connect to other infected clients, or
open infected emails. The Outbreak Defense Strategy was designed to manage
outbreaks at every point along the outbreak lifecycle.

Current Status
Displays the on-going status of your clients and network in response to a current
worldwide virus outbreak. The status roughly corresponds to the outbreak lifecycle.
Outbreak Defense first takes preventative measures such as informing you of the
threat and taking action as prescribed in the Outbreak Prevention Policy (downloaded
from TrendLabs). Next, your clients are protected from the threat when updated
components are downloaded from the Trend Micro ActiveUpdate server and
deployed. Finally, Damage Cleanup Services, using newly updated components,
starts to clean infected and damaged files, and remove virus remnants.

Manual and Scheduled Scans

This chapter describes Manual and Scheduled scans and how to use Manual and
Scheduled scan to protect your network and clients from viruses, malware, and other
threats.
The topics discussed in this chapter include:
• Manual and Scheduled Scans on page 10-1
• Scanning Desktops and Servers for Viruses, Spyware, and Other Malware Threats
on page 10-3
• Scanning Exchange Servers for Viruses, Malware, and Other Threats on page 10-5

Manual and Scheduled Scans

Client Server Messaging Security provides three types of scans to protect your clients
from viruses, malware, and other types of malicious code: Manual Scan, Scheduled
Scan, and Real-time Scan. Each scan has a different purpose and use, but all are
configured approximately the same way. This chapter discusses Manual and
Scheduled Scans.

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

About Scans for Desktops and Servers

Manual Scan – Occurs after user execution and completely scans all specified files.
The length of the scan depends on the number of files and your hardware resources.
Scheduled Scan – A scheduled scan completely scans all files at the time and
frequency configured. Use scheduled scans to automate routine scans on your clients
and improve virus management efficiency.

About Scans for Exchange Servers

Manual scans
Client Server Messaging Security performs manual and scheduled scanning, on
demand, according to a manual prompt. Manual scanning eliminates viruses from
inside the Information Store databases, eradicates old virus infections, and minimizes
the possibility of reinfection. When performing a manual scan, Client Server
Messaging Security takes actions against threats according to the administrator’s
configurations. You can abort manual scan by clicking Stop Scanning when the scan
is in progress.
Client Server Messaging Security does not allow the selection of individual Stores
for scanning.
Manual scanning makes use of the following filters:
• Antivirus
• Content Filtering
• Attachment Blocking
To configure a Manual scan, click Scans > Manual Scan.
Scheduled scans
Scheduled scans occur according to the schedule you have configured. If user wants
to disable Scheduled Scan, they have to clear all check boxes for "Antivirus",
"Content Filtering", and "Attachment Blocking" under Scans > Scheduled Scan.
Scheduled scanning makes use of the following filters:
• Antivirus
• Content Filtering

Manual and Scheduled Scans

Scanning Exchange Servers for Viruses,

Malware, and Other Threats
Manual and scheduled scanning on the Microsoft Exchange server is similar to
traditional hard drive antivirus scanning. However, Client Server Messaging
Security, unlike traditional antivirus scanners, can support the Microsoft Exchange
database format, and can scan files and documents stored on Exchange servers.
You can run a manual scan to ensure that Client Server Messaging Security scans all
messages in the Information Store once. Completely scanning the Information Store
in this way minimizes the chance of infections from unexpected sources such as
unprotected mail servers or improper configurations. Manual scanning scans the
entire Information Store by default.
If you begin a manual scan when a scheduled scan is running, the scheduled scan is
interrupted. The scheduled scan aborts, but runs again according to its schedule.
You can perform virus scanning, attachment blocking, and content filtering through
manual scanning. These filters are similar to those used during real-time scanning,
except some actions are not available during manual or scheduled scanning.
To configure Manual or Scheduled Scans for Exchange servers:
1. Click Scans > Manual Scan or Scheduled Scan to open the Scan screen.
2. Select the Exchange server(s) to scan.
See File Types Eligible for Scanning on page 8-5 for more detailed information.
3. Optional: Set the scanning options by clicking the Exchange server name.
To learn more about configuring scan options for Exchange servers see Trend
Micro Default Scan Settings on page 8-3, or the Getting Started Guide.
4. Click Scan Now to run a Manual Scan or click Save to save the Scheduled Scan
settings.
To set a time for Scheduled Scans:
1. Click Scans > Scheduled Scan to open the Scheduled Scan screen.
2. Click the Schedule tab. A table displaying a list of all scannable clients appears.
3. For each client create a schedule using the following UI elements:

• Daily – Click to perform Scheduled Scan every day

• Weekly, every – Click to perform a Scheduled Scan once a week. You must
select a day from the list and a start time. The time selected is the time that
Client/Server Security will perform the scan.
• Monthly, on day – Click to perform a Scheduled Scan once a month. You
must select a date from the list and a start time.
Regardless of the selection, specify when to start scheduled updates in the Start
time lists.
4. Click Save.

Tip: Trend Micro recommends that you do not schedule a scan to run at the same time as
you set for a scheduled update. This may cause the scheduled scan to stop
unexpectedly. Similarly, if you begin a manual scan when a scheduled scan is
running, the scheduled scan is interrupted. The scheduled scan aborts, but
runs again according to its schedule.

Note: To disable Scheduled Scan, deselect all options for the specific desktop, server, or
Exchange server, and click Save.

Completely scanning the Information Store in regularly scheduled scans minimizes

the chance of infections from unexpected sources such as unprotected mail servers or
improper configurations. Scheduled scanning scans the entire Information Store by
default.

Note: When running manual or scheduled scan, you may see the message message from
"" [total 0 recipient(s)] on the real-time monitor page. These are mail
scan logs for Exchange System Mails.

Tip: Trend Micro recommends that you set Client Server Messaging Security to run
scheduled scans at regular intervals for optimal protection of your desktops, servers,
or Exchange Information Store.

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

• To ensure that client computers stay up-to-date, CSA runs a scheduled update
every 8 hours.
The Trend Micro recommended settings for component updates provide reasonable
protection to small and medium-sized business. If necessary, you can run Manual
updates or modify the Scheduled updates.
Trend Micro updates the scan engine or program generally only during the release of
a new Client Server Messaging Security version. However, Trend Micro releases
pattern files every day to keep your client virus protection current.

Using Update Agents

If you identify sections of your network between clients and the Trend Micro
Security Server as "low-bandwidth" or "heavy traffic", you can specify Client/Server
Security Agent clients to act as update sources (Update Agents) for other clients. This
helps distribute the burden of deploying components to all clients.
For example, if your network is segmented by location, and the network link between
segments experiences a heavy traffic load, Trend Micro recommends allowing at
least one client on each segment to act as an Update Agent.
To allow one or more clients to act as Update Agents:
1. On the main menu, click Updates > Source. The update source screen appears.
2. Click the Security Agents tab.
3. Under the Assign Update Agent(s) section, click Add. The Add an Update Agent
screen appears.

can be rolled back.

The Security Server uses the following scan engines:

• Virus scan engine 32-bit
• Virus scan engine 64-bit
You need to roll back these types of scan engines separately. The rollback procedures
for both types of scan engines are the same. The Trend Micro Security Server retains
only the current and the previous versions of the scan engine and the last five pattern
files.

Removing Inactive Client/Server Security Agents

When you use the Client/Server Security Agent (CSA) uninstallation program to
remove the CSA program from a computer, the program automatically notifies the
Security Server. When the Security Server receives this notification, it removes the
client icon from the Security Groups Tree to show that the client does not exist
anymore.
However, if the CSA is removed using other methods, such as reformatting the
computer hard drive or deleting the client files manually, the Security Server will not

14-9

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

be aware of the removal and it will display the CSA as inactive. If a user unloads or
disables the client for an extended time, the Security Server also displays the CSA as
inactive.
To have the Security Groups Tree only display active clients, you can configure the
Security Server to remove inactive CSAs from the Security Groups Tree
automatically.
To enable the automatic removal of inactive CSAs, configure the following options:
• Enable automatic removal of inactive Client/Server Security Agent – Select
this option to enable the automatic removal of clients that have not made contact
with the Security server for a specific number of days.
• Automatically remove a Client/Server Security Agent if inactive for {} days –
Choose the number of days that a client is allowed to be inactive before it is
removed from the Security Dashboard.

Verifying Client-Server Connectivity

Client Server Messaging Security represents the client connection status in the
Security Groups Tree using icons. However, certain conditions may prevent the
Security Groups Tree from displaying the correct client connection status. For
example, if the network cable of a client is accidentally unplugged, the client will not
be able to notify the Trend Micro Security Server that it is now offline. This client
will still appear as online in the Security Groups Tree.
You can verify client-server connection manually or by schedule from the Security
Dashboard.

Note: Verify Connection does not allow the selection of specific groups or clients. It verifies
the connection to all clients registered with the Trend Micro Security Server.

You can perform verification of client-server connection automatically and manually

by configuring the following options:
• Enable scheduled verification – Select this check box to enable scheduled
verification of client-security server communication.
• Verify Now – Click this if you want to instantly test for client-security server
connectivity.

Maintaining the Quarantine Folder

Whenever a client detects an Internet threat in a file and the scan action for that type
of threat is quarantine, the Client/Server Security Agent program encrypts the
infected file, places it in the Client/Server Security Agent’s suspect folder, and sends
it to the Trend Micro Security Server quarantine folder. Client Server Messaging
Security encrypts the infected file to prevent it from infecting other files.
The default location of Client/Server Security Agent suspect folder is as follows:
C:\Program Files\Trend Micro\Client Server Security Agent\SUSPECT

The default location of Trend Micro Security Server quarantine folder is as follows:
C:\Program Files\Trend Micros\Security Server\PCCSRV\Virus

Note: If the client is unable to send the encrypted file to the Trend Micro Security Server for
any reason, such as network connection problems, the encrypted file remains in the
client’s suspect folder. The client attempts to resend the file when it reconnects to the
Trend Micro Security Server.

For more information on configuring scan settings, or changing the location of the
quarantine folder, see Virus Scan Settings on page 14-6.
From the Global Settings screen, you can configure the capacity of the quarantine
folder and the maximum individual file size for every infected file that can be stored
in it.
To following options are available to help you manage the quarantine folder:
• Quarantine folder capacity – Type an amount in MB for the capacity of the
Quarantine folder.
• Maximum size for a single file – Type an amount for the size of single folder
stored in the Quarantine folder.
• Delete All Quarantined Files – Click this to delete all files in the Quarantine
folder instantly.

Vulnerability Scanner
Use Vulnerability Scanner to detect installed antivirus solutions and to search for
unprotected computers on your network. To determine if computers are protected,
Vulnerability Scanner pings ports that are normally used by antivirus solutions.
Vulnerability Scanner can perform the following functions:
• Perform a DHCP scan to monitor the network for DHCP requests so that when
computers first log on to the network, Vulnerability Scan can determine their status
• Ping computers on your network to check their status and retrieve their computer
names, platform versions, and descriptions
• Determine the antivirus solutions installed on the network. It can detect Trend
Micro products (including OfficeScan, ServerProtect for Windows NT and Linux,
ScanMail for Microsoft Exchange, InterScan Messaging Security Suite, and
PortalProtect) and third-party antivirus solutions (including Norton AntiVirus
Corporate Edition v7.5 and v7.6, and McAfee VirusScan ePolicy Orchestrator).
• Display the server name and the version of the pattern file, scan engine and
program for OfficeScan and ServerProtect for Windows NT
• Send scan results via email
• Run in silent mode (command prompt mode)
• Install the Client/Server Security Agent remotely on computers running Windows
Vista/2000/XP (Professional only)/Server 2003 (R2)

This section contains information about Client Server Messaging Security client
tools.

Client Packager
Client Packager is a tool that can compress setup and update files into a
self-extracting file to simplify delivery via email, CD-ROM, or similar media. It also
includes an email function that can access your Microsoft Outlook address book and
allow you to send the self-extracting file from within the tool’s console.
To run Client Packager, double-click the file. Client/Server Security clients that are
installed using Client Packager report to the server where the setup package was
created.

Restore Encrypted Virus

Client/Server Security Agents and Messaging Security Agents encypt infected files
and attachments to prevent users from opening them and spreading viruses to other
files on the computer.
Whenever Client/Server Security Agent backs up, quarantines, or renames an
infected file, it encrypts the file. The quarantined file is stored in the \Suspect
folder on the client, and then sent to the quarantine directory. The backup file is
stored in the \Backup folder of the client, typically in C:\Program

15-8

Using Administrative and Client Tools

Files\Trend Micro\Client Server Security

Agent\Backup\. Whenever Messaging Security Agent backs up, quarantines,
or archives a mail or attachment, it encrypts the file and stores it in the MSA storage
folder, typically in C:\Program Files\Trend Micro\Messaging
Security Agent\storage\.
However, there may be some situations when you have to open the file even if you
know it is infected. For example, an important document has been infected and you
need to retrieve the information from the document, you will need to decrypt the
infected file to retrieve your information. You can use Restore Encrypted Virus to
decrypt infected files from which you want to open.

Note: To prevent Client/Server Security from detecting the virus again when you use
Restore Encrypted Virus, exclude the folder to which you decrypt the file from
Real-time Scan.

WARNING! Decrypting an infected file may spread the virus to other files.

Restore Encrypted Virus requires the following files:

• Main file: VSEncode.exe
• Required DLL file: Vsapi32.dll
To decrypt files in the Suspect folder:
1. On the client where you want to decrypt an infected file, open Windows Explorer
and go to the \PCCSRV\Admin\Utility\VSEncrypt folder of Client/Server
Security.
2. Copy the entire VSEncrypt folder to the client computer.

Note: Do not copy the VSEncrypt folder to the Client/Server Security folder. The
Vsapi32.dll file of Restore Encrypted Virus will conflict with the original
Vsapi32.dll.

3. Open a command prompt and go to the location where you copied the VSEncrypt
folder.

CSM4SMB-v3-AG.book Page 10 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

4. Run Restore Encrypted Virus using the following parameters:

• no parameter: encrypt files in the Suspect folder
• -d: decrypt files in the Suspect folder
• -debug: create debug log and output in the root folder of the client
• /o: overwrite encrypted or decrypted file if it already exists
• /f: {filename}: encrypt or decrypt a single file
• /nr: do not restore original file name
For example, you can type VSEncode [-d] [-debug] to decrypt files in the
Suspect folder and create a debug log. When you decrypt or encrypt a file, the
decrypted or encrypted file is created in the same folder.

Note: You may not be able to encrypt or decrypt files that are locked.

Restore Encrypted Virus provides the following logs:

• VSEncrypt.log – Contains the encryption or decryption details. This file is
created automatically in the temp folder for the user logged on the machine
(normally, on the C: drive).
• VSEncDbg.log – Contains the debug details. This file is created automatically in
the temp folder for the user logged on the machine (normally, on the C: drive) if
you run VSEncode.exe with the -debug parameter.
To encrypt or decrypt files in other locations:
1. Create a text file and then type the full path of the files you want to encrypt or
decrypt.
For example, if you want to encrypt or decrypt files in C:\My
Documents\Reports, type C:\My Documents\Reports\*.* in the text
file. Then save the text file with an INI or TXT extension, for example, you can
save it as ForEncryption.ini on the C: drive.
2. At a command prompt, run Restore Encrypted Virus by typing VSEncode.exe
-d -i {location of the INI or TXT file}, where {location of the INI or TXT
file} is the path of the INI or TXT file you created (for example,
C:\ForEncryption.ini).

Touch Tool
The Touch Tool synchronizes the time stamp of one file with the time stamp of
another file or with the system time of the computer. If you unsuccessfully attempt to
deploy a hot fix (an update or patch that Trend Micro releases) on the Trend Micro
Security Server, use the Touch Tool to change the time stamp of the hot fix. This
causes Client/Server Security to interpret the hot fix file as new, which makes the
server attempt to deploy the hot fix again automatically.
To run the Touch Tool:
1. On the Trend Micro Security Server, go to the following directory:
\PCCSRV\Admin\Utility\Touch

2. Copy the TMTouch.exe file to the folder where the file you want to change is
located. If synchronizing the file time stamp with the time stamp of another file,
put both files in the same location with the Touch tool.
3. Open a command prompt and go to the location of the Touch Tool.
4. Type the following:
TmTouch.exe <destination_filename> <source_filename>

where:
<destination_filename> = the name of the file (the hot fix, for example) whose
time stamp you want to change
<source_filename> = the name of the file whose time stamp you want to replicate

If you do not specify a source filename, the tool sets the destination file time
stamp to the system time of the computer.

Note: You can use the wildcard character "*" in the destination file name field, but not the
source file name field.

5. To verify the time stamp changed, type dir in the command prompt or right
click the file in Windows explorer and select Properties.

Client Mover
If you have more than one Client Server Messaging Security server on the network,
you can use Client Mover to transfer clients from one Client Server Messaging
Security server to another.
This is especially useful after adding a new Client Server Messaging Security server
to the network when you want to transfer existing clients to the new server. The two
Client Server Messaging Security servers must be of the same type and same
language version.
Client Mover requires the IPXfer.exe file.
To run Client Mover:
1. On the Client Server Messaging Security server, go to the following directory:
\PCCSRV\Admin\Utility\IPXfer.
2. Copy the IPXfer.exe file to the client that you want to transfer.
3. On the client, open a command prompt and then go to the folder where you
copied the file.
4. Run Client Mover using the following syntax:
IPXfer.exe -s <server_name> -p <server_listening_port> -m 1
-c <client_listening_port>

where:
• <server_name> = the server name of the destination Client Server
Messaging Security server (the server to which the client will transfer)
• <server_listening_port> = the listening (trusted) port of the
destination Client Server Messaging Security server. To view the listening
port on the Security Dashboard, click Security Settings. The listening port is
shown next to the Security Server name.
• 1 = You must use the number "1" after "-m"
• <client_listening_port> = the port number of the client machine
To confirm the client now reports to the other server, do the following:
1. On the client, right click the CSA icon in the system tray.
2. Click Client/Server Security Agent Console.

What Do the Terms Mean?

Computer security is a rapidly changing subject. Administrators and information
security professionals invent and adopt a variety of terms and phrases to describe
potential risks or uninvited incidents to computers and networks. The following is a
discussion of these terms and their meanings as used in this document.
Some of these terms refer to real security risks and some refer to relatively harmless,
but annoying or unsolicited incidents. Trojans, viruses, and worms are examples of
terms used to describe real security risks. Joke programs and other grayware are
terms used to describe incidents that might be harmful, but are sometimes simply
annoying and unsolicited. The Messaging Security Agent can protect Exchange
servers against all of the incidents described in this chapter.

Viruses
A computer virus is a segment of code that has the ability to replicate. Viruses
usually replicate by infecting files. When a virus infects a file, it attaches a copy of
itself to the file in such a way that when the former executes, the virus also runs.
When this happens, the infected file also becomes capable of infecting other files.
Like biological viruses, computer viruses can spread quickly and are often difficult to
eradicate.
In addition to replication, some computer viruses share another commonality: a
damage routine that delivers the virus payload. While payloads may only display
messages or images, they can also destroy files, reformat your hard drive, or cause
other damage. Even if the virus does not contain a damage routine, it can cause
trouble by consuming storage space and memory, and degrading the overall
performance of your computer.
Generally, there are three kinds of viruses:
• File – File viruses may come in different types– there are DOS viruses, Windows
viruses, macro viruses, and script viruses. All of these share the same
characteristics of viruses except that they infect different types of host files or
programs.
• Boot – Boot viruses infect the partition table of hard disks and boot sector of hard
disks and floppy disks.

17-2
CSM4SMB-v3-AG.book Page 3 Monday, April 23, 2007 10:40 AM

Understanding the Threats

• Script – Script viruses are viruses written in script programming languages, such
as Visual Basic Script and JavaScript and are usually embedded in HTML
documents.
VBScript (Visual Basic Script) and Jscript (JavaScript) viruses activate themselves
using Microsoft's Windows Scripting Host. They then infect other files. Since
Windows Scripting Host is available on Windows 98, Windows 2000 and other
Windows operating systems, the viruses can be activated simply by
double-clicking a *.vbs or *.js file from Windows Explorer.
What is so special about script viruses? Unlike programming binary viruses, which
require assembly-type programming knowledge, virus authors programs script
viruses as text. A script virus can achieve functionality without low-level
programming and with code as compact as possible. It can also use predefined
objects in Windows to make accessing many parts of the infected system easier
(for example, for file infection, for mass-mailing). Furthermore, since the code is
text, it is easy for others to read and imitate the coding paradigm. Because of this,
many script viruses have several modified variants.
For example, shortly after the “I love you” virus appeared, antivirus vendors found
modified copies of the original code, which spread themselves with different
subject lines, or message bodies.
Whatever their type is, the basic mechanism remains the same. A virus contains code
that explicitly copies itself. In the case of file viruses, this usually entails making
modifications to gain control when a user accidentally executes the infected program.
After the virus code has finished execution, in most cases, it passes back the control
to the original host program to give the user an impression that nothing is wrong with
the infected file.
Take note that there are also cross-platform viruses. These types of viruses can infect
files belonging to different platforms (for example, Windows and Linux). However,
such viruses are very rare and seldom achieve 100% functionality.

Network Viruses
A virus spreading over a network is not, strictly speaking, a network virus. Only
some of the threats mentioned above, such as worms, qualify as network viruses.
Specifically, network viruses use network protocols, such as TCP, FTP, UDP, HTTP,
and email protocols to replicate. They often do not alter system files or modify the
boot sectors of hard disks. Instead, network viruses infect the memory of client

17-3
CSM4SMB-v3-AG.book Page 4 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

machines, forcing them to flood the network with traffic, which can cause
slowdowns and even complete network failure. Because network viruses remain in
memory, they are often undetectable by conventional disk-based file I/O scanning
methods.
Personal Firewall works with a network virus pattern file to identify and block
network viruses (see the on-line help for more information about configuring the
Personal Firewall).

Trojans
A Trojan is a malicious program that masquerades as a harmless application. Unlike
viruses, Trojans do not replicate but can be just as destructive. An application that
claims to rid your computer of viruses when it actually introduces viruses onto your
computer is an example of a Trojan. Traditional antivirus solutions can detect and
remove viruses but not Trojans, especially those that are already running on the
system.

Bots
Bots are compressed executable files that are designed with the intent to cause harm
to computer systems and networks. Bots, once executed, can replicate, compress, and
distribute copies of themselves.

Packers
A packer is a compressed and/or encrypted Windows or Linux executable program,
often a Trojan. Compressing executables makes them more difficult for Antivirus
products to detect.

Worms
A computer worm is a self-contained program (or set of programs) that is able to
spread functional copies of itself or its segments to other computer systems. The
propagation usually takes place via network connections or email attachments.
Unlike viruses, worms do not need to attach themselves to host programs. Worms
often use email and applications, such as Microsoft™ Outlook™, to propagate. They

17-4
CSM4SMB-v3-AG.book Page 5 Monday, April 23, 2007 10:40 AM

Understanding the Threats

may also drop copies of themselves into shared folders or utilize file-sharing systems,
such as Kazaa, under the assumption that users will likely download them, thus
letting the worm propagate. In some cases, worms replicate themselves using chat
applications such as ICQ, AIM, mIRC, or other Peer-to-Peer (P2P) programs.

About ActiveX
ActiveX is a technology from Microsoft that handles interaction between Web
browsers, Microsoft applications, other third party applications, and the computer
operating system. ActiveX makes use of ActiveX controls– software components
installed on computers that add specialized functionality to Web pages, such as
animation and interactive programs.
Creators of spyware and other grayware often mask their applications as legitimate
ActiveX controls. When your users view Web sites that require ActiveX
functionality, they may knowingly or unknowingly download the ActiveX controls to
their computers and unwittingly install grayware applications.
Two related ways to help guard against spyware and other grayware that are masked
as ActiveX controls are as follows:
• Setting client Web browser security to prompt the user before installing ActiveX
applications
• Educating your users to look out for applications that could be grayware when they
download any files, controls, or applications to their browsers

About Mass-Mailing Attacks

Email-aware viruses, like the infamous Melissa, Loveletter, AnnaKournikova and
others, have the ability to spread via email by automating the infected computer's
email client. Mass-mailing behavior describes a situation when an infection spreads
rapidly between clients and servers in an Exchange environment. Mass-mailing
attacks can be expensive to clean up and cause panic among users. Trend Micro
designed the scan engine to detect behaviors that mass-mailing attacks usually
demonstrate. The behaviors are recorded in the Virus Pattern file that is updated
using the TrendLabs™ ActiveUpdate Servers.
You can enable the Messaging Security Agent to take a special action against
mass-mailing attacks whenever it detects a mass-mailing behavior. The action set for

17-5
CSM4SMB-v3-AG.book Page 6 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

mass-mailing behavior takes precedence over all other actions. The default action
against mass-mailing attacks is delete.
For example, you configure the Messaging Security Agent to quarantine messages
when it detects a worm or a Trojan in an email message. You also enable
mass-mailing behavior and set the Messaging Security Agent to delete all messages
that demonstrate mass-mailing behavior. The Messaging Security Agent receives a
message containing a worm such as a variant of MyDoom. This worm uses its own
SMTP engine to send itself to email addresses that it collects from the infected
computer. When the Messaging Security Agent detects the MyDoom worm and
recognizes its mass-mailing behavior, it will delete the email message containing the
worm - as opposed to the quarantine action for worms that do not show mass-mailing
behavior.

About Compressed Files

Compression and archiving are among the most common methods of file storage,
especially for file transfers - such as email attachments, FTP, and HTTP. Before any
virus detection can occur on a compressed file, however, you must first decompress
it. Recognizing the fundamental importance of decompression in the detection of
viruses, Trend Micro is committed to supporting all major decompression routines,
present and future. For other compression file types, the Messaging Security Agent
performs scan actions on the whole compressed file, rather than individual files
within the compressed file.
The Messaging Security Agent currently supports the following compression types:
• Extraction–used when multiple files have been compressed or archived into a
single file: PKZIP, LHA, LZH, ARJ, MIME, MSCF, TAR, GZIP, BZIP2, RAR,
and ACE.
• Expansion–used when only a single file has been compressed or archived into a
single file: PKLITE, PKLITE32, LZEXE, DIET, ASPACK, UPX, MSCOMP,
LZW, MACBIN, and Petite.
• Decoding–used when a file has been converted from binary to ASCII, a method
that is widely employed by email systems: UUCODE and BINHEX.

17-6
CSM4SMB-v3-AG.book Page 7 Monday, April 23, 2007 10:40 AM

Understanding the Threats

Note: When the Messaging Security Agent does not support the compression type,
then it cannot detect viruses in compression layers beyond the first compression
layer.

When the Messaging Security Agent encounters a compressed file it does the
following:
1. The Messaging Security Agent extracts the compressed files and scans them.
The Messaging Security Agent begins by extracting the first compression layer.
After extracting the first layer, the Messaging Security Agent proceeds to the
second layer and so on until it has scanned all of the compression layers that the
user configured it to scan up to a maximum of six.
2. The Messaging Security Agent performs a user-configured action on infected
files.
The Messaging Security Agent performs the same action against infected files
detected in compressed formats as for other infected files. For example, if you
configure the action for infected files to be quarantine, then the Messaging
Security Agent quarantines messages in which it detects infected files.
The Messaging Security Agent can clean files from two types of compression
routines: PKZIP and LHA. However, the Messaging Security Agent can only
clean the first layer of files compressed using these compression routines.

About Macro Viruses

Macro viruses are application-specific. They infect macro utilities that accompany
such applications as Microsoft Word (.doc) and Microsoft Excel (.xls). Therefore,
they can be detected in files with extensions common to macro capable applications
such as .doc, .xls, and .ppt. Macro viruses travel between data files in the application
and can eventually infect hundreds of files if undeterred.
As these file types are often attached to email messages, macro viruses spread readily
by means of the Internet in email attachments.
How the Messaging Security Agent prevents macro viruses from infecting your
Exchange server:

You can take many steps to prevent the installation of spyware and other types of
grayware onto your client computers. Trend Micro suggests making the following
standard practices part of the anti-spyware/grayware initiative in your organization:
• Follow the recommended Client/Server Security configuration steps in this
chapter.
• Educate your client users to do the following:
Read the End User License Agreement (EULA) and included documentation of
applications they download and install on their computers.
Click No to any message asking for authorization to download and install software
unless the client users are certain both the creator of the software and the Web site
they are viewing are trustworthy.
Disregard unsolicited commercial email (spam), especially if the spam asks users
to click a button or hyperlink.
• Configure Web browser settings that ensure a strict level of security. Trend Micro
recommends requiring Web browsers to prompt users before installing ActiveX
controls. To increase the security level for Internet Explorer (IE), go to Tools >
Internet Options > Security and move the slider to a higher level. If this setting
causes problems with Web sites you want to visit, click Sites..., and add the sites
you want to visit to the trusted sites list.
• If using Microsoft Outlook, configure the security settings so that Outlook does not
automatically download HTML items, such as pictures sent in spam messages.
Creators of spyware and grayware often use pictures.

Understanding the Threats

• Disallow the use of peer-to-peer file-sharing services. Spyware and other grayware
applications may be masked as other types of files your users may want to
download, such as MP3 music files.
• Periodically examine the installed software on your client computers and look for
applications that may be spyware or other grayware. If you find an application or
file that Client Server Messaging Security cannot detect as grayware but you think
is a type of grayware, send it to Trend Micro:
http://subwiz.trendmicro.com/SubWiz.
Trend Labs will analyze the files and applications you submit.
If you prefer to communicate via email, send a message to the following address:
virusresponse@trendmicro.com

SeeContacting Technical Support on page 18-14 for more information.

• Keep your Windows operating systems updated with the latest patches from
Microsoft. See the Microsoft Web site for details.

Troubleshooting
This section helps you troubleshoot issues that may arise during installation, upgrade,
migration, and deployment.

User’s Spam Folder not Created

When the administrator creates a mailbox account for a user, the mailbox entity is not
created immediately in Exchange server, but will be created under the following
conditions:
• An end user logs on to their mailbox for the first time
– or –
• The first email arrives at the mailbox
The administrator must first create the mailbox entity and the user must log on before
EUQ can create a spam folder.

Internal or External Sender/Recipient Confusion

You can only define one domain as the internal address for the Messaging Security
Agent. If you use Exchange System Manager to change your primary address on a
server, Messaging Security Agent does not recognize the new address as an internal
address because Messaging Security Agent cannot detect that the recipient policy has
changed. Type a new internal address and save.
For example: You have two email addresses for a domain: @trend_1.com and
@trend_2.com. You set @trend_1.com as the primary address. Messaging Security
Agent considers email messages with the primary address to be internal (that is,
abc@trend_1.com, or xyz@trend_1.com are internal). Later, you use Exchange
System Manager to change the primary address to @trend_2.com. This means that
Exchange now recognizes addresses such as abc@trend_2.com and
xyz@trend_2.com to be internal addresses. However, Messaging Security Agent still
considers these addresses to be external.

FAQs, Troubleshooting and Technical Support

Re-sending a Quarantine Message Fails

Resending a quarantine message fails. This can happen when the system mailbox on
the Exchange server environment does not exist. To resolve the problem, edit the
following in the registry keys: ResendMailbox, ResendMailboxDomain, and
ResendMailSender to assign another mailbox.

Settings Replication
You can only replicate settings from a source Messaging Security Agent to a target
Messaging Security Agent that share the same domain. Messaging Security Agent is
unable to replicate settings when the source Messaging Security Agent is located in
the parent domain, and the target Messaging Security Agent(s) is located in the child
domain (or vice versa), because it lacks the required permission.
To solve this problem, perform the following:
For Windows 2003 operating system:
1. Execute regedit.
2. Go to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
SecurePipeServers\winreg

3. Right click winreg > Permissions

4. Add Smex Admin Group of target domain, and enable Allow Read
For Windows Vista/2000 operating system:
1. Execute regedt32
2. Go to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurePi

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

Some Client Server Messaging Security Components are

not Installed
Licenses to various components of Trend Micro products may differ by region. After
installation, you will see a summary of the components your Registration
Key/Activation Code allows you to use. Check with your vendor or reseller to verify
the components for which you have licenses.

Unable to Access the Web Console

There are several potential causes of this problem.

Browser Cache
If you upgraded from a previous version of CSM, Web browser and proxy server
cache files may prevent the Security Dashboard from loading properly. Clear the
cache memory on your browser and on any proxy servers located between the Trend
Micro Security Server and the computer you use to access the Security Dashboard.

SSL Certificate
Also, verify that your Web server is functioning properly. If you are using SSL,
verify that the SSL certificate is still valid. See your Web server documentation for
details.

Virtual Directory Settings

There may be a problem with the virtual directory settings If you are running the
Security Dashboard on an IIS server and the following message appears:
The page cannot be displayed
HTTP Error 403.1 - Forbidden: Execute access is denied.
Internet Information Services (IIS)
This message may appear when either of the following addresses is used to access the
console:
http://<server name>/SMB/
http://<server name>/SMB/default.htm

FAQs, Troubleshooting and Technical Support

However, the console may open without any problems when using the following
address:
http://<server name>/SMB/console/html/cgi/cgichkmasterpwd.exe

To resolve this issue, check the execute permissions of the SMB virtual directory.
Do the following:
1. Open the Internet Information Services (IIS) manager.
2. In the SMB virtual directory, select Properties.
3. Select the Virtual Directory tab and change the execute permissions to Scripts
instead of none.
Also change the execute permissions of the client install virtual directory.

Incorrect Number of Clients on the Security Dashboard

You may see that the number of clients reflected on the Security Dashboard is
incorrect.
This happens if you retain client records in the database after client program removal.
For example, if client-server communication is lost while removing the client, the
server does not receive notification about the client removal. The server retains client
information in the database and still shows the client icon on the console. When you
reinstall the client, the server creates a new record in the database and displays a new
icon on the console.
Use the Verify Connection feature through the Security Dashboard to check for
duplicate client records. For more information on the Verify Connection feature, refer
to Verifying Client-Server Connectivity on page 14-10.

Unsuccessful Installation from Web Page or Remote

Install
If users report that they cannot install from the internal Web page or if
installation with Remote Install is unsuccessful, try the following:
• Verify that client -server communication exists by using ping and telnet
• Verify that you have administrator privileges to the target computer where you
want to install the client

• Check if TCP/IP on the client is enabled and properly configured

• Check if the target computer meets the minimum system requirements
• Check if any files have been locked
• If you have limited bandwidth, check if it causes connection timeout between the
server and the client
• If you are using a proxy server for client-server communication, check if the proxy
settings are configured correctly
• Open a Web browser on the client, type http://{Server name}:{server
port} /SMB/cgi/cgionstart.exe in the address text box, and then press
ENTER. If the next screen shows -2, this means the client can communicate with
the server. This also indicates that the problem may be in the server database; it
may not have a record of the client computer.
• Delete Trend Micro add-ons and browsing history.
a. Close and re-open Internet Explorer.
b. In Internet Explorer, click Tools > Internet Options.
The Internet Option window appears.
c. In the Browsing History section, click Delete.

FAQs, Troubleshooting and Technical Support

Client Icon Does Not Appear on Security Dashboard after

Installation
You may discover that the client icon does not appear on the Security Dashboard
after you install the client. This happens when the client is unable to send its status to
the server.
To resolve this, do the following:
• Verify that client-server communication exists by using ping and telnet
• If you have limited bandwidth, check if it causes connection timeout between the
server and the client
• Check if the \PCCSRV folder on the server has shared privileges and if all users
have been granted full control privileges
• Verify that the Trend Micro Security Server proxy settings are correct
• Open a Web browser on the client, type http://{Trend Micro Security
Server_Name}:{port number}/SMB/cgi/cgionstart.exe in the address
text box, and then press ENTER. If the next screen shows -2, this means the client
can communicate with the server. This also indicates that the problem may be in
the server database; it may not have a record on the client.

Issues During Migration from Third-party Antivirus

Software
This section discusses some issues you may encounter when migrating from
third-party antivirus software.

Client Migration
The setup program for the Client/Server Security Agent utilizes the third-party
software’s uninstallation program to automatically remove it from your users’ system
and replace it with the Client/Server Security Agent. If automatic uninstallation is
unsuccessful, users get the following message:
Uninstallation failed.

There are several possible causes for this error:

Trend Micro Outbreak Prevention Policy

The Trend Micro Outbreak Prevention Policy is a set of Trend Micro recommended
default security configuration settings that are applied in response to an outbreak on
the network.
The Outbreak Prevention Policy is downloaded from Trend Labs to the Trend Micro
Security Server.
When the Trend Micro Security Server detects an outbreak, it determines the degree
of the outbreak and immediately implements the appropriate security measures as
stated in the Outbreak Prevention Policy.
Based on the Outbreak Prevention Policy, Automatic Threat Response takes the
following preemptive steps to secure your network in the event of an outbreak:
• Blocks shared folders to help prevent viruses from infecting files in shared folders
• Blocks ports to help prevent viruses from using vulnerable ports to infect files on
the network and clients
• Denies write access to files and folders to help prevent viruses from modifying
files
• Displays an alert message on clients running the Client/Server Security Agent

Trend Micro Damage Cleanup Services

Client Server Messaging Security uses Damage Cleanup Services (DCS) to protect
your Windows computers against Trojans (or Trojan horse programs) and viruses.

The Damage Cleanup Services Solution

To address the threats posed by Trojans and viruses, DCS does the following:
• Detects and removes live Trojans and active malicious code applications
• Kills processes that Trojans and other malicious applications create
• Repairs system files that Trojans and malicious applications modify
• Deletes files and applications that Trojans and malicious applications drop
To accomplish these tasks, DCS makes use of these components:
• Virus cleanup engine – The engine Damage Cleanup Services uses to scan for and
remove Trojans and Trojan processes
• Damage cleanup template – Used by the virus cleanup engine, this template helps
identify Trojan files and processes so the engine can eliminate them
In Client Server Messaging Security, DCS runs on the client on these occasions:
• Client users perform a manual cleanup from the client main console
• You perform Cleanup Now on the client from the Trend Micro Security Dashboard
for SMB
• Client users run Manual or Scheduled Scan.
• After hot fix or patch deployment (see for more information)
• When the Client Server Messaging Security service is restarted (the Client Server
Messaging Security client Watchdog service must be selected to restart the client
automatically if the client program unexpectedly terminates. Enable this feature on
the Global Client Settings screen. See the Administrator’s Guide and Client
Server Messaging Security online help for details.)
Because DCS runs automatically, you do not need to configure it. Users are not even
aware when it is executed because it runs in the background (when the client is
running). However, Client Server Messaging Security may sometimes notify the user

B- 2
CSM4SMB-v3-AG.book Page 3 Monday, April 23, 2007 10:40 AM

to restart their computer to complete the process of removing a Trojan or grayware

application.

Vulnerability Assessment
Vulnerability Assessment provides system administrators or other network security
personnel with the ability to assess security risks to their networks. The information
they generate by using Vulnerability Assessment gives them a clear guide as to how
to resolve known vulnerabilities and secure their networks.
Use Vulnerability Assessment to:
• Configure tasks that scan any or all computers attached to a network. Scans can
search for single vulnerabilities or a list of all known vulnerabilities.
• Run manual assessment tasks or set tasks to run according to a schedule.
• Request blocking for computers that present an unacceptable level of risk to
network security.
• Create reports that identify vulnerabilities according to individual computers and
describe the security risks those computers present to the overall network. The
reports identify the vulnerability according to standard naming conventions so that
security personnel can do further research to resolve the vulnerabilities and secure
the network.
• View assessment histories and compare reports to better understand the
vulnerabilities and the changing risk factors to network security.

Trend Micro IntelliScan

IntelliScan is a new method of identifying files to scan. For executable files (for
example, .zip and .exe), the true file type is determined based on the file content. For
non-executable files (for example, .txt), the true file type is determined based on the
file header.
Using IntelliScan provides the following benefits:
• Performance optimization – IntelliScan does not affect crucial applications on the
client because it uses minimal system resources

B-3
CSM4SMB-v3-AG.book Page 4 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

• Shorter scanning period – Because IntelliScan uses true file type identification, it
only scans files that are vulnerable to infection. The scan time is therefore
significantly shorter than when you scan all files.

Trend Micro ActiveAction

Different types of viruses require different scan actions. Customizing scan actions for
different types of viruses requires knowledge about viruses and can be a tedious task.
ActiveAction is a set of pre-configured scan actions for viruses and other types of
Internet threats. The recommended action for viruses is Clean, and the alternative
action is Quarantine. The recommended action for Trojans and joke programs is
Quarantine.
If you are not familiar with scan actions or if you are not sure which scan action is
suitable for a certain type of virus, Trend Micro recommends using ActiveAction.
Using ActiveAction provides the following benefits:
• Time saving and easy to maintain – ActiveAction uses scan actions that are
recommended by Trend Micro. You do not have to spend time configuring the scan
actions.
• Updateable scan actions – Virus writers constantly change the way viruses attack
computers. To help ensure that clients are protected against the latest threats and
the latest methods of virus attacks, new ActiveAction settings are updated in virus
pattern files.

Trend Micro IntelliTrap

IntelliTrap detects malicious code such as bots in compressed files. Virus writers
often attempt to circumvent virus filtering by using different file compression
schemes. IntelliTrap is a real-time, rule-based, and pattern recognition scan engine
technology that detects and removes known viruses in files compressed up to six
layers deep using any of 16 popular compression types.

B- 4
CSM4SMB-v3-AG.book Page 5 Monday, April 23, 2007 10:40 AM

True File Type

When set to scan true file type, the scan engine examines the file header rather than
the file name to ascertain the actual file type. For example, if the scan engine is set to
scan all executable files and it encounters a file named “family.gif,” it does not
assume the file is a graphic file. Instead, the scan engine opens the file header and
examines the internally registered data type to determine whether the file is indeed a
graphic file, or, for example, an executable that someone named to avoid detection.
True file type scanning works in conjunction with IntelliScan to scan only those file
types known to be of potential danger. These technologies can mean a reduction in
the overall number of files that the scan engine must examine (perhaps as much as a
two-thirds reduction), but with this reduction comes a potentially higher risk.
For example, .gif files make up a large volume of all Web traffic, but they are
unlikely to harbor viruses, launch executable code, or carry out any known or
theoretical exploits. Therefore, does this mean they are safe? Not entirely. It is
possible for a malicious hacker to give a harmful file a “safe” file name to smuggle it
past the scan engine and onto the network. This file could cause damage if someone
renamed it and ran it.

Tip: For the highest level of security, Trend Micro recommends scanning all files.

About ActiveAction
Different types of viruses require different scan actions. Customizing scan actions for
different types of viruses can be a tedious task. For this reason, Trend Micro created
ActiveAction.
ActiveAction is a set of pre-configured scan actions for viruses and other types of
threats. The recommended action for viruses is Clean, and the alternative action is
Quarantine. The recommended action for Trojans and joke programs is Quarantine.
If you are not familiar with scan actions or if you are not sure which scan action is
suitable for a certain type of virus, Trend Micro recommends using ActiveAction.
Using ActiveAction brings you the following benefits:

CSM4SMB-v3-AG.book Page 6 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

• Effort-saving maintenance – ActiveAction uses Trend Micro scan actions. You

do not have to spend time customizing the scan actions.
• Updateable scan actions – Virus writers constantly change the way viruses attack
computers.
To ensure that clients are protected against the latest threats and the latest methods of
virus attacks, Trend Micro updates ActiveAction settings in every new pattern file.

Planning a Pilot Deployment

Before performing a full-scale deployment, Trend Micro recommends that you first
conduct a pilot deployment in a controlled environment. A pilot deployment provides
an opportunity to determine how features work and what level of support you will
likely need after full deployment.
It also gives your installation team a chance to rehearse and refine the deployment
process and test if your deployment plan meets your organization’s antivirus needs.

Tip: Although this phase is optional, Trend Micro highly recommends conducting a pilot
deployment before doing a full-scale deployment.

Choosing a Pilot Site

Choose a pilot site that matches your production environment. Try to simulate the
type of network topology that would serve as an adequate representation of your
production environment.

Creating a Rollback Plan

Trend Micro recommends creating a disaster recovery or rollback plan in case there
are issues with the installation or upgrade process.

C-1
CSM4SMB-v3-AG.book Page 2 Monday, April 23, 2007 10:40 AM

Trend Micro™ Client Server Messaging Security 3.6 for SMB™ Administrator’s Guide

This process should take into account company information security policies, as well
as technical specifics.

Deploying Your Pilot

Evaluate the different deployment methods (see Overview of Installation and
Deployment on page 3-2) to see which ones are suitable for your particular
environment.

Evaluating Your Pilot Deployment

Create a list of successes and failures encountered throughout the pilot process.
Identify potential pitfalls and plan accordingly for a successful deployment. This
pilot evaluation plan can be rolled into the overall production deployment plan.

Server (for example, notebook computers). These clients continue to provide
antivirus protection, but have delays in sending their status to the server.
Assign roaming privileges to clients that are disconnected from the Trend Micro
Security Server for an extended period.
Roaming clients get updated only on these occasions:
• When the client performs Update Now or performs a Scheduled Update.
• When client connects to the Trend Micro Security Server.
For more information on how to update clients, see the Trend Micro Security Server
online help.

Spyware Types
The Trend Micro anti-spam engine can detect 21 types of spyware. The following
table identifies these spyware types and provides a threat description for each type.
These spyware types may appear in the Spyware/Grayware Type column on the
Spyware/Grayware Log Details page.

Spyware Type Threat Description

Trackware Trackware is a generic term that describes software that collects a

computers demographic and usage information and sends it to some
remote server via the Internet, where it can be used by other people in a
variety of different ways including marketing.

Adware Adware is a type of software that displays advertisements on the computer

screen while a computer is running. Typically, AdWare is built into software
that performs some other primary task such as file sharing.

The justification for AdWare is for the software developer to recover

revenue via advertising instead of for instance charging for their software.
Some Adware will collect the computers usage information (e.g. sites
visited) and send it up to a remote server on the Internet where it is
collected and processed for marketing purposes.

Spyware Type Threat Description

Cookie Cookies are small files that are created by your Web browser when you visit
sites on the Internet. Typically, they are used as a convenience to
remember frequently used information that is required for access to a
particular Web site. They can also be used to track your visits to certain
Web sites and can provide companies with information about frequency of
visits and other profile information. The user is usually not aware that their
surfing habits are being tracked.

Trend Micro Anti-Spyware identifies cookies that are created by the most
common advertising companies and allows you to clean them, which helps
to ensure your privacy while surfing.

Dialer A program that usually configures some sort of dial up configuration such as
a dial-up-networking connection in Windows. The user either knowingly or
unknowingly will end up using the dialer that calls a time-charged number
that is usually billed to your credit card.

General The threat type is not known, or is not yet classified.

KeyLogger/Monit A type of software can be either commercially sold or may be installed

oring Software inadvertently via the Internet. This software can allow people to monitor you
keystrokes, your computer screen, etc. and can even allow remote access.

Trojan A type of software that is installed unknowingly, usually as a result of

installing some other software, or viewing an email. Since it exists as a
software program on the computer, the range of activity of a Trojan can be
quite broad, from usage monitoring to remote control to customized
collection and theft of information.
Suspect This item is suspect, because Trend Micro Anti-Spyware detected some
characteristics that match a known spyware.

Browser Hijacker A type of software that changes settings in your Web browser. This often
includes changing your browser's default home page.
Parasite A type of software that piggybacks onto other software. This type of
software may be installed without the user's knowledge or consent.

Browser Helper A type of module that acts as a plugin to Internet Explorer browser. Some
Object BHOs may monitor or manipulate your Web surfing.
Layered Service A type of module that acts as a plugin to your Network System. LSPs
Provider usually have low level access to your network and Internet data.
URL Shortcut A shortcut to a URL that exists in your Internet Browser or your desktop.

Peer To Peer Software that allows users to exchange shared files over the Internet.

Worm Software that propagates by creating duplicates of itself on other

computers.

Downloader Software that manages the download of other software onto computers.

Term Description

boot sector A sector is a designated portion of a disk (the physical device on which data
viruses is written and read). The boot sector contains the data used by your
computer to load and initialize the computer's operating system. A boot
sector virus infects the boot sector of a partition or a disk.

bots Bots are compressed executable files that are designed with the intent to
cause harm to computer systems and networks. Bots, once executed, can
replicate, compress, and distribute copies of themselves.

clean To remove virus code from a file or message.

Cleanup Cleanup detects and removes Trojans and applications or processes

installed by Trojans. It repairs files modified by Trojans.

client A computer system or process that requests a service of another computer

system or process (a “server”) using some kind of protocol and accepts the
server's responses. A client is part of a client-server software architecture.
Note that the online help uses the term “Client computer” in a special way to
refer to computers that form a client-server relationship to the Client Server
Messaging main program, the Security Server.

client computers The Client computers are all the desktops, laptops, and servers where the
CSAs are installed. Exchange servers protected by Messaging Security
Agents are also considered to be Client computers. CSAs perform Antivirus
scanning and Firewall configurations on Client desktops and servers.
Messaging Security Agents perform Antivirus scanning, Anti-spam filtering,
email Content Filtering, and Attachment Blocking on Exchange servers.

compressed file A single file containing one or more separate files plus information to allow
them to be extracted by a suitable program, such as WinZip.

COM and EXE file A type of virus that masquerades as an application by using a .exe or .com
infectors file extension.

Term Description

domain name The full name of a system, consisting of its local host name and its domain
name, for example, tellsitall.com. A domain name should be sufficient to
determine a unique Internet address for any host on the Internet. This
process, called “name resolution”, uses the Domain Name System (DNS).

Dynamic Host A device, such as a computer or switch, must have an IP address to be

Control Protocol connected to a network, but the address does not have to be static. A
(DHCP) DHCP server, using the Dynamic Host Control Protocol, can assign and
manage IP addresses dynamically every time a device connects to a
network.

encryption Encryption is the process of changing data into a form that can be read only
by the intended receiver. To decipher the message, the receiver of the
encrypted data must have the proper decryption key. Lacing decryption
codes, CSAs cannot scan encrypted files.

End User License An End User License Agreement or EULA is a legal contract between a
Agreement software publisher and the software user. It typically outlines restrictions on
(EULA) the side of the user, who can refuse to enter into the agreement by not
clicking “I accept” during installation. Clicking “I do not accept” will, of
course, end the installation of the software product.

Many users inadvertently agree to the installation of spyware and other

types of grayware into their computers when they click “I accept” on EULA
prompts displayed during the installation of certain free software.
Exceptions Exceptions, in relation to the Firewall, are a list of ports and communication
protocols that will not be blocked by the Firewall. Exceptions also describe
the ports that you have set so that they are never blocked during Outbreak
Defense protection measures.

false positives A false positive occurs when a Web site, URL, “infected” file, or email
message is incorrectly determined by filtering software to be of an
unwanted type. For example, a legitimate email between colleagues may
be detected as spam if a job-seeking filter does not distinguish between
resume (to start again) and résumé (a summary of work experience).

file name The portion of a file name (such as .dll or .xml) which indicates the kind of
extension data stored in the file. Apart from informing the user what type of content the
file holds, file name extensions are typically used to decide which program
to launch when a file is run.

File Transfer FTP is a standard protocol used for transporting files from a server to a
Protocol (FTP) client over the Internet. Refer to Network Working Group RFC 959 for more
information.

file type The kind of data stored in a file. Most operating systems use the file name
extension to determine the file type. The file type is used to choose an
appropriate icon to represent the file in a user interface, and the correct
application with which to view, edit, run, or print the file.

Term Description

firewall Firewalls create a barrier between the Internet and your local network to
protect the local network from hacker attacks and network viruses.
Firewalls examine data packet to determine if they are infected with a
network virus.

FQDN (fully A fully qualified domain name (FQDN) consists of a host and domain name,
qualified domain including top-level domain. For example, www.trendmicro.com is a fully

Term Description

macro viruses A type of virus encoded in an application macro and often included in a
document.

malware A malware is a program that performs unexpected or unauthorized actions.

It is a general term used to refer to viruses, Trojans, and worms. Malware,
depending on their type, may or may not include replicating and non
replicating malicious code.

message body The content of an email message.

Network virus Viruses that use network protocols, such as TCP, FTP, UDP, HTTP, and
email protocols to replicate. They often do not alter system files or modify
the boot sectors of hard disks. Instead, network viruses infect the memory
of computers, forcing them to flood the network with traffic, which can
cause slowdowns and even complete network failure.

Notifications The Security Server can send your system administrator a notification
whenever significant abnormal events occur on your Client computers. For
example: You can set up a condition that whenever the CSA detects 40
viruses within one hour, the Security Server will send a notification to the
system administrator.

Outbreak During Outbreak Defense, the Security Server enacts the instructions
Defense contained in the Outbreak Prevention Policy. The Trend Micro Outbreak
Prevention Policy is a set of recommended default security configurations
and settings designed by TrendLabs to give optimal protection to your
computers and network during outbreak conditions. The Security Server
downloads the Outbreak Prevention Policy from Trend Micro ActiveUpdate
server every 30 minutes or whenever the Security Server starts up.
Outbreak Defense enacts preemptive measures such as blocking shared
folders, blocking ports, updating components, and running scans.

phishing incident A Phish is an email message that falsely claims to be from an established or
legitimate enterprise. The message encourages recipients to click on a link
that will redirect their browsers to a fraudulent Web site where the user is
asked to update personal information such as passwords, social security
numbers, and credit card numbers in an attempt to trick a recipient into
providing private information that will be used for identity theft.

Phish sites A Web site that lures users into providing personal details, such as credit
card information. Links to phish sites are often sent in bogus email
messages disguised as legitimate messages from well-known businesses.

Ping of Death A Denial of Service attack where a hacker directs an oversized ICMP
packet at a target computer. This can cause the computers buffer to
overflow, which can freeze or reboot the machine.

Term Description

port number A port number, together with a network address - such as an IP number,
allow computers to communicate across a network. Each application
program has a unique port number associated with it. Blocking a port on a
computer prevents an application associated with that port number from
sending or receiving communications to other applications on other
computers across a network. Blocking the ports on a computer is an
effective way to prevent malicious software from attacking that computer.

privileges From the Security Dashboard, administrators can set privileges for the
(desktop CSAs. End users can then set the CSAs to scan their Client computers
privileges) according to the privileges you allowed. Use desktop privileges to enforce a
uniform antivirus policy throughout your organization.

proxy server A World Wide Web server which accepts URLs with a special prefix, used to
fetch documents from either a local cache or a remote server, then returns
the URL to the requester.

quarantine To place infected data such as email messages, infected attachments,

infected HTTP downloads, or infected FTP files in an isolated directory (the
Quarantine Directory) on your server.

remote The term “remote” refers to a computer that is connected through a network
to another computer, but physically distant from that computer.

rules (content Content filtering rules are rules that you set up to filter the content of email
filtering) messages. You define undesirable content and sources and set the
Messaging Security Agent to detect and take action against such content
violations.
scan To examine items in a file in sequence to find those that meet a particular
criteria.

scan engine The module that performs antivirus scanning and detection in the host
product to which it is integrated.
Secure Socket SSL is a scheme proposed by Netscape Communications Corporation to

security server When you first install Client Server Messaging Security, you install it on a
Windows server that becomes the Security Server. The Security Server
communicates with the CSAs and the Messaging Security Agents installed
on Client computers. The Security Server also hosts the Security
Dashboard, the centralized Web management console for the entire Client
Server Messaging Security solution.

server A program which provides some service to other (client) programs. The
connection between client and server is normally by means of message
passing, often over a network, and uses some protocol to encode the
client's requests and the server's responses. Note that the online help uses
the term “Security Server” in a special way to refer to the server that forms a
client-server relationship with the computers on your network to which you
have installed the CSAs.

Transport to server, and client to server, over the internet.
Protocol (SMTP)

SOCKS 4 A TCP protocol used by proxy servers to establish a connection between

clients on the internal network or LAN and computers or servers outside the
LAN. The SOCKS 4 protocol makes connection requests, sets up proxy
circuits and relays data at the Application layer of the OSI model.

spam Unsolicited email messages meant to promote a product or service.

Telnet Telnet is a standard method of interfacing terminal devices over TCP by
creating a "Network Virtual Terminal". Refer to Network Working Group
RFC 854 for more information.

Test virus An inert file that acts like a real virus and is detectable by virus-scanning
software. Use test files, such as the EICAR test script, to verify that your
antivirus installation is scanning properly.

Transmission A connection-oriented, end-to-end reliable protocol designed to fit into a

Control Protocol layered hierarchy of protocols which support multi-network applications.
(TCP) TCP relies on IP datagrams for address resolution. Refer to DARPA

perform malicious acts, such as open ports for hackers to enter.

updates Updates describe a process of downloading the most up-to-date

components such as pattern files and scan engines to your computer.

virus A virus is a program that replicates. To do so, the virus needs to attach itself
to other program files and execute whenever the host program executes.
