 The Basics of Cyber
Security
Essential Concepts for Screen Owners

Before we dive into digital signage cyber security specifics,

grasp these foundational principles:

Understanding Threats

Cyber threats, such as malware, phishing, ransomware,

unauthorized access, data breaches, and insider threats, can
harm your screens and data. Recognizing them empowers
proactive protection.

Asset Identification
Identify assets needing safeguarding:

1
Hardware: Digital displays, media players, servers.
Software: Digital signage software and applications.
Data: Customer info, content, ads, vital digital assets.

Your Guide to Cyber Security 5

for Digital Signage and OOH Screens
 Risk Assessment

 Physical and Device
Security
Protecting the Heart of Your Digital Signage

Before we dive into digital signage cyber security specifics,

grasp these foundational principles:

Securing Hardware: The First Line of Defense

Protecting the physical components of your digital signage

infrastructure is the first line of defense against potential
threats. Here are steps to consider:

Access Control: Restrict physical access to

your screens. Place digital signage equipment
in secure enclosures or cabinets, away from
unauthorized personnel.

Locking Mechanisms: Equip cabinets with

robust locks or security latches to deter
tampering or unauthorized access.

Unique Keys: Ensure that keys or access

codes are unique and only provided to
authorized personnel.

Your Guide to Cyber Security 7

for Digital Signage and OOH Screens
 Surveillance: Consider installing security
cameras in strategic locations to monitor the
physical integrity of your hardware. Visible
cameras act as a deterrent and can provide
valuable evidence in case of tampering or
theft.

Access Control: Digital Defense for Your Screens

In addition to physical security measures, enforcing strict digital

access control is essential:

Strong Passwords: Implement strong and

unique passwords for all digital signage devices.
These passwords should be known only to
authorized personnel and should be changed
regularly.

Multi-Factor Authentication (MFA): Enhance

security by requiring multiple forms of
verification before granting access. MFA adds
an extra layer of protection against unauthorized
entry.

USB Access Control: Disable USB ports on

your media players and screens to prevent
the introduction of malicious software
through external storage devices.

Your Guide to Cyber Security 8

for Digital Signage and OOH Screens
 Logging and Tracking: Maintaining Accountability

Keeping records of maintenance access and changes is a crucial

aspect of maintaining security:

Access Logs: Maintain detailed

access logs that record when,
where, and by whom
maintenance access is granted.

Change Tracking: Keep a record

of any changes made to your
digital signage configurations or
content. This includes software
updates, content uploads, and
system modifications.

Audit Trails: Establish audit trails

to track changes over time,
making it easier to identify and
rectify any unauthorized
alterations.

 Software and Network
Security
Defending Against Remote Threats

Cyber threats often originate from remote locations, targeting your

digital signage network from afar. To protect your screens from
these remote attacks, consider the following measures:

Software Updates: A Crucial Defense

Staying up-to-date is a fundamental aspect of digital signage

security. Ensure your digital signage software and antivirus
solutions are consistently updated:

Digital Signage Software: Regularly update your digital

signage software to apply security patches and feature
enhancements. Outdated software can be a vulnerable
entry point for attackers.

Antivirus Solutions: Maintain up-to-date antivirus software

on all devices within your digital signage network. Regular
scans and definition updates are essential to detect and
prevent malware infections.

for Digital Signage and OOH Screens
 Strong Passwords: The Frontline of Defense

A strong password policy is a cornerstone of cyber security.

Enforce strong, unique passwords for all devices and accounts
associated with your digital signage ecosystem:

Device Access: Implement strong passwords for digital

signage media players, screens, and any other hardware
within your infrastructure.

Account Credentials: Ensure that all user accounts

associated with your digital signage network have robust,
unique passwords. Encourage the use of passphrases for
added security.

Password Managers: Simplify and Secure Password Management

Managing numerous passwords can be a daunting task. Simplify

and secure this process with dedicated password management
tools:

Password Managers: Consider using password managers

that generate and securely store complex passwords. This
enables your team to maintain unique credentials for each
account without the burden of memorization.

Your Guide to Cyber Security 11

for Digital Signage and OOH Screens
 Remote Management: Secure Software Updates

Efficiently manage software updates while maintaining security:

Secure Remote Management Software: Utilize secure

remote management software solutions, such as
TeamViewer or VNC, to facilitate the updating of firmware
and software on your media players. Ensure that access to
these tools is restricted to approved personnel with proper
authentication.

Operating System Support: Stay Within Supported Versions

Choose operating systems that are actively supported by their

parent companies:

Operating System Compliance: Ensure that all devices

within your digital signage network operate on supported
operating systems. Operating systems like Android 10+,
Windows 8.1+, and Linux Kernel v5.15.85+ typically receive
security updates and patches, reducing vulnerabilities.

Your Guide to Cyber Security 12

for Digital Signage and OOH Screens
 DNS Filtering: Guard Against Malicious Content

DNS filtering is an effective way to block access to malicious

sites and content:

Blacklist Filtering: Implement a DNS blacklist that blocks

requests to known malicious or inappropriate sites. This
adds an extra layer of protection against unwanted content
appearing on your screens.

Dynamic Updates: Regularly update your DNS blacklist to

adapt to evolving threats, making it more challenging for
cybercriminals to exploit your network.

Internal Network Security: Protect Your In-Office Network

Your internal network, which your team uses to access the

internet, is another access point that requires security measures:

Intrusion Detection Systems: Consider deploying intrusion

detection systems (IDS) on your in-office network. IDS
monitors network traffic for suspicious activity and alerts
administrators when intervention is needed.

Your Guide to Cyber Security 13

for Digital Signage and OOH Screens
 Test Environment: Isolating Risk

Maintaining a separate network for safe software experimentation

can help isolate potential risks:

Separate Test Network: Establish a separate network for

testing new software, HTML packages, or other digital
signage components. Isolating these experiments prevents
potential hackers from using them as entry points to your
main digital signage media players.

By implementing these software and network security measures, you can

strengthen your defences against remote cyber threats and ensure the
reliability of your digital signage network.
