Security Manager Dons Hacker Hat for a Change
So far, I've downloaded five tools: Firewalk, Nmap, Sniffit, Swatch and Tripwire. All are publicly available.
Firewalk was designed to determine what filtering rules your firewall uses and to map the network beyond it. Firewalk is a means of finding what holes already exist in firewalls to allow authorized traffic; an unauthorized attacker could potentially take advantage of this information to gain access through the firewall. The tool was written by someone who delights in deconstructing systems to find out more about them.
