Kali Linux

Kali Linux is an open source project funded by Offensive Security, a worldwide provider of information security training and penetration testing services.

In addition to Kali Linux, Passive Security maintains the Exploit Database and its free online course, Metasploit Unleashed. Prepared for Kali Linux users, formerly called BackTrack, BackTrack is a program that meets all your computer's security needs. BackTrack, which is a combination of Whax * and Auditor ** and designed to meet the security needs in the best way, is mostly preferred by advanced Linux users. With the new version, novice users can take advantage of BackTrack.
