Best Operating Systems (OS) for Hacking/Pentesting

Top 5 

#1 Kali Linux

Kali Linux is an advanced penetration testing tool that should be a part of every security professional’s toolbox. Penetration testing involves using a variety of tools and techniques to test the limits of security policies and procedures. What Kali has done is collect just about everything you’ll need in a single CD. It includes more than 300 different tools, all of which are open source and available on GitHub.

#2 BackTrack 5r3

The evolution of BackTrack spans many years of development, penetration tests, and unprecedented help from the security community. BackTrack originally started with earlier versions of live Linux distributions called Whoppix, IWHAX, and Auditor. When BackTrack was developed, it was designed to be an all in one live cd used on security audits and was specifically crafted to not leave any remnants of itself on the laptop. It has since expanded to being the most widely adopted penetration testing framework in existence and is used by the security community all over the world.

#3 BackBox Linux

BackBox is a Linux distribution based on Ubuntu. It has been developed to perform penetration tests and security assessments. Designed to be fast, easy to use and provide a minimal yet complete desktop environment, thanks to its own software repositories, always being updated to the latest stable version of the most used and best known ethical hacking tools.

#5 NodeZero Linux

Penetration testing and security auditing requires specialist tools.The natural path leads us to collecting them all in one handy place. However how that collection is implemented can be critical to how you deploy effective and robust testing. All though NodeZero Linux can be used as a ‘Live System’ for occasional testing, its real strength comes from the understanding that a tester requires a strong and efficient system. This is achieved in our belief by working at a distribution that is a permanent installation, that benefits from a strong selection of tools, integrated with a stable linux environment.
