The new version 2.0 of KALI has just been released. Kali-linux is a GNU / Linux distribution specialized in auditing and pentesting (penetration testing) based on the GNU / Linux distribution debian.
Kali Linux took over from Backtrack, which was based on Slackware until version 3 and then Ubuntu from version 4.
The goal of Kali Linux is to provide a distribution grouping together all the tools necessary for network security testing.
This new version is based on Debian Jessie and on a Kernel 4.0, considerably improving driver support (including network / wireless) for laptops, the use of gnome 3 Desktop, but also a multitude of graphical environments such as KDE, Xfce, MATE, e17, lxde and i3wm are available there ... and especially the support of ruby 2.0 greatly improving the speed of Metasploit.
Time is now a distribution that will now be updated regularly. No need to wait 2 years to be up to date :). Thanks to continuous monitoring of the Git repositories of the various tools offered in Kali, updated packages and improvements relating to the OS and drivers will be pushed regularly without having to wait for the release of major versions of Kali Linux.
You can download Kali Linux on their beautiful site.
