Practical No: 05
Aim: Implementation of Windows security using firewalls and other tools.
Tools: Windows Defender Firewall
Description:
Windows Firewall is a security feature that helps to protect your device by filtering
network traffic that enters and exits your device. This traffic can be filtered based on
several criteria, including source and destination IP address, IP protocol, or source and
destination port number. Windows Firewall can be configured to block or allow network
traffic based on the services and applications that are installed on your device. This
allows you to restrict network traffic to only those applications and services that are
explicitly allowed to communicate on the network.
The default behavior of Windows Firewall is to:
• block all incoming traffic, unless solicited or
matching a rule
• allow all outgoing traffic, unless matching a rule
Firewall rules
Firewall rules identify allowed or blocked network traffic, and the conditions for this
to happen. The rules offer an extensive selection of conditions to identify traffic,
including:
• Application, service or program name
• Source and destination IP addresses
• Can make use dynamic values, like default gateway, DHCP servers, DNS
servers and local subnets
• Protocol name or type. For transport layer protocols, TCP and UDP, you can
specify ports or port ranges. For custom protocols, you can use a number
between 0 and 255 representing the IP protocol Interface type
• ICMP/ICMPv6 traffic type and code
