The creators of BackTrack have released a new, advanced Penetration Testing Linux distribution named Kali Linux. BackTrack 5 was the last major version of the BackTrack distribution. The creators of BackTrack decided that to move forward with the challenges of cyber security and modern testing a new foundation was needed. Kali Linux was born and released on March 13th, 2013. Kali Linux is based on Debian and an FHS-compliant filesystem.

Kali has many advantages over BackTrack. It comes with many more updated tools. The tools are streamlined with the Debian repositories and synchronized four times a day. That means users have the latest package updates and security fixes. The new compliant filesystems translate into running most tools from anywhere on the system. Kali has also made customization, unattended installation, and flexible desktop environments strong features in Kali Linux.

Kali Linux is available for download at http://www.kali.org/.
