There are many options available today for users looking at Linux distributions tailored for security research, and among them is BackBox Linux, which was updated to version 4.1 on Jan. 29. Backbox Linux 4.1 is based on the Ubuntu 14.04 LTS distribution and uses the Xfce desktop environment. BackBox Linux is not intended to primarily be a user-focused privacy distribution, as is the case with Tails , but rather is more aligned with Pentoo , CAINE and Kali Linux, all of which focus on providing tools for security analysis.
