Kali Linux is a Debian-based rolling Linux distribution designed for use as a digital forensics operating system. It is maintained and funded by Offensive Security Ltd. It was originally developed by Mati Aharoni and Devon Kearns of Offensive Security by rewriting BackTrack, a Linux distribution they had previously written for forensics.
Kali Linux comes with a number of pre-installed penetration tests, including nmap, Wireshark, John the Ripper, and Aircrack-ng. Users can run Kali Linux on a hard drive, live CD, or live USB. It is available for the x86 instruction set. There are also ARM-based images for Raspberry Pi and Samsung ARM Chromebook.
