I've been trying to install Linux because more and more hacker tools seem to be available for it. The combination of power, flexibility and the open-source community seems to be very attractive to hackers. Web sites such as the Nomad Mobile Research Centre and Securify Inc.'s Packet Storm regularly offer new Linux tools. I want to be able to try these tools and see what they can do, just so I can keep an eye on new developments and find out how others could see our network.

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.
