Firewall: Packet Filters

Firewall: Packet Filters

This brief interactive activity, by Electromechanical Digital Library and Wisconsin Technical College System faculty members Joseph Wetzel and Douglas Tabbutt, provides an interactive lesson on packet filters to demonstrate their use. After a brief explanation, there is a very useful activity that allows the user to control theoretical settings to try to block a certain port from transferring information – it's a good test to verify if the concept is understood. This should prove a useful resource for students or teachers looking to introduce the concept of packet filters.
