Simon Fraser University Firewalls Question

Cisco is a pioneer in producing a variety of firewall applications with many features. To configure any Cisco firewall, IP Access Control List (ACL) is used. The document “Tutorial on Cisco Firewall Rule Format” describes the general format of ACL, and also shows how ACL can filter network traffic. Please read this document to get a perspective on how to configure a CISCO Firewall using ACLs.

Apart from Cisco, there are many other vendors in the market that produce different types of firewalls. For this part of the assignment, you will survey any four commercially available firewalls from four different vendors, and write a summary comparing their technical features and capabilities, benefits, and limitations.
