A firewall is an appliance (a combination of hardware and software) or an application (software) designed to control the flow of Internet Protocol (IP) traffic to or from a network or electronic equipment. Firewalls are used to examine network traffic and enforce policies based on instructions contained within the firewall's ruleset. Firewalls represent one component of a strategy to combat malicious activities and assaults on computing resources and network-accessible information. Other components include, but are not limited to, antivirus software, intrusion detection software, patch management, strong passwords/passphrases, and spyware detection utilities.

ITS provides guidance on when firewalls are required or recommended.
