BlackArch Linux is an open source distribution of Linux derived from the lightweight and powerful Arch Linux operating system and designed from the ground up to be used by security professionals for penetration testing tasks and security auditing.
While the distribution can be installed on top of an existing Arch Linux installation, the main attraction of this Linux Security Distriution is the Live DVDs, which support both 32-bit (i386) and 64-bit (x86_64) hardware platforms
While the default graphical session is powered by Fluxbox, this arch based linux security distribution also includes the i3, WMii, Spectrwm, awesome, dwm and Openbox window managers. Keep in mind though, that you must first log in using the root/blackarch username/password combination. Except for the fact that it uses a custom background image with the BlackArch Linux logo, the boot loader includes the same boot entries as in the standard Arch Linux ISO images, allowing the user to boot the operating system, boot an existing OS, run a memory test, view detailed hardware information, as well as to reboot or shutdown the PC.
