    Kali Linux

    The most well-known and used Linux distro for hacking and penetration testing is Kali Linux. It’s based on Debian and was developed by Offensive Security taking on the mantle of BackTrack.

    Kali Linux follows the Rolling Release model in that every tool that comes with the distro, of which there are plenty, is updated automatically. Kali is the most advanced penetration testing platform available. As such, its tools focus largely around penetration testing from various fields of security and forensics.

    DEFT is typically paired up with the forensics system for the Windows operating system known as Digital Advanced Response Toolkit, or DART. DART contains the best possible tools you’ll find for forensics and incident response.

    The staff who developed DEFT are consistently helping to develop new systems that help law enforcement, the military, and government officers.

    Samurai Web Testing Framework

    The Samurai Web Testing Framework comes as a virtual machine and was developed for online penetration testing. It’s based off of Ubuntu and contains plenty of amazing open source tools that prioritize website attacks.

    One of the more interesting and convenient features of the Samurai Web Testing Framework is that it includes a pre-configured Wiki set up to store information during your penetration tests.

    This framework does come with a few prerequisites such as Vagrant, which is a developmental environment that works best with VirtualBox.

    Pentoo Linux

    The Gentoo Linux-based Pentoo is a distro focused on security and penetration testing. It’s available as a LiveCD with persistence support which means that all changes conducted while live will remain and become available on the next boot up so long as you’re using a USB stick.

    Pentoo is a carbon copy of Gentoo except with a large assortment of customized tools with a focus toward security and penetration testing. Anyone familiar with the workings and interface of Gentoo will easily adapt to the Pentoo work environment. It’s also available as an overlay to anyone who already uses Gentoo as their preferred Linux distro for hacking.


    If your current or potential career is that of a forensics specialist, then Computer Aided INvestigative Environment (CAINE) is the distro for you. It was created with the sole purpose of aiding in and testing of digital forensics.
