From Pathfinder Wiki
A system designed to prevent unauthorized access to or from a private network. Firewalls can be implemented in both hardware and software, or a combination of both. Firewalls are frequently used to prevent unauthorized Internet users from accessing private networks connected to the Internet, especially intranets. All messages entering or leaving the Internet pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria.
