The implementation of network firewalls can be a difficult concept for students to grasp initially. Our Network Firewall Visualization tool, a capstone project created by our students, uses visualization (the graphical display of a simulation) to convey and teach network security and firewall configuration to students of all levels. This tool is intended to teach and reinforce key concepts including the use and purpose of a perimeter firewall, the use of separated subnets, the purposes behind packet filtering, and the shortcomings of a simple packet filter firewall. The expectation was that through the use of this tool students will gain a better understanding of the importance and use of network firewalls and their role in network security. This paper outlines the rationale behind the creation of the tool, how the tool is used in a classroom environment and demonstrates the improved understanding of the role of firewalls by students after using the tool in a guided classroom environment. The findings of this paper suggest a better student comprehension on written assessments following structured usage of this tool.
