Many security practitioners have been using BackTrack to perform their security assessments. BackTrack is an open-source Linux-based penetration testing toolset. BackTrack made performing a security assessment easier because all of the common tools that you needed were all packaged into one nice distribution and ready to go at a moment’s notice. BackTrack contains so many security tools that it is too difficult to list them all. If you want to see a complete list of all the tools just run “dpkg –list”. BackTrack made it easy to create a new VM from the downloaded ISO, perform the assessment, then either archive that VM for future reference or delete it when done to remove the evidence. The latest version of BackTrack is version 5 release 3 and it came out on August 13, 2012. If you want to explore this version, you can download it from this site. But before, you do, check out Kali Linux first.
