Material Detail
Firewall: Network Address Translation/Port Address Translation
This brief interactive activity, by Electromechanical Digital Library and Wisconsin Technical College System faculty members Joseph Wetzel and Douglas Tabbutt, provides a basic lesson on firewalls. This learning activity introduces the purpose of a firewall and a simple overview of what a firewall does within a computer system. The illustrations are helpful to identifying the separate parts and this would be a good resource for students that are being introduced to the topic.
