Hi Folks, I would like to share some interesting information on firewall testing There are 3 important phases in firewall testing Firewall Compatibility / Functionality Testing Performance and Stress Testing Security Testing Firewall Functionality testing simulates the "real-world" scenarios and compliance testing. Performance and Stress Testing is done to isolate any scalability issues or limitations of the firewall product and determines the performance o f the firewall at boundary or near-boundary levels defined. Security Testing covers the vulnerability of the firewall product against DoS, DDoS attacks, application/port vulnerabilities. California software labs has published a white paper on firewall testing in detail. Thanks and Regards Rob
