Vulnerability detection tools for firewalls

[svykobdk]

I need to test our firewall for vulnerability from the internet. Can anyone recommend a simple and efficient test tool for this purpose (portscan etc.)

thanks

This is a pretty good scanner and it is free. Scroll down about half way and click the "Shields Up" link. Common & custom ports scanned and a few other nice tricks to tell you what someone can easily retrive from computers that are behind the firewall.

Portscanner for Windows, at least one that you have control what you are scanning and how !

SuperScan from Founstone:

nmap windows

Opensource portscanners linux:

- namp

Linux is still the platform for all that kind of tools.

By the the way a Vulnerablity scanner and a Port scanner is a huge diffrence !!!

A good vulnerability scanner for linux is:
