Six Linux Distributions for Penetration Testing

During a penetration test, security experts systematically examine the target system for vulnerabilities. Several Linux distributions have been specifically designed for this purpose. We present the six most important distributions along with their respective strengths and weaknesses.

Kali: The Top Dog Among Pentest Distributions

Kali Linux is the most widely used distribution for penetration testing and is based on Debian. It ships with an extensive collection of pentest tools, allowing you to repurpose any system for security testing quickly and easily. The distribution also runs in VirtualBox on a Windows system. Its comprehensive toolset covers all the key areas across various testing scenarios. Detailed documentation ensures a smooth onboarding experience, and a large, active community is ready to help when questions arise.

Parrot: Modern Distribution With Cloud Support and Encryption

Parrot is a newer distribution for penetration testing that places particular emphasis on cloud applications, online anonymity, and integrated system encryption. It is also based on Debian and uses MATE as its desktop environment. Like Kali, Parrot Security OS comes with all essential pentest tools pre-installed. Additionally, Parrot offers several exclusive utilities developed by Frozenbox Network.

Testing Web Applications With Samurai

If your focus is specifically on testing web applications for vulnerabilities, Samurai is the right choice. This specialized web pentest distribution is based on Ubuntu and can also be launched in VirtualBox and VMWare, making it operational on any system in minutes. You can start testing right away since the most important tools come pre-installed. A built-in documentation tool also streamlines the process of recording your findings. Samurai is an open-source project and available free of charge.

Santoku: Mobile Apps in Focus

While Samurai focuses on web apps, Santoku is a Linux distribution designed specifically for mobile application penetration testing. Its pre-installed tools cover mobile forensics as well as security and malware analysis. You can download the distribution free of charge from the vendor's website.

Keep It Simple: BlackArch

BlackArch is based on Arch Linux, benefiting from the speed and simplicity of that foundation without compromising on pentest functionality. Many Linux distributions offer a broad toolset and extensive customization options, but for specific use cases they can feel overloaded. Arch Linux takes a different approach, consistently favoring simplicity and a lean architecture.

Live Linux Distribution for Pentests: PenToo

Insert a CD or USB stick and start pentesting right away -- that is exactly what PenToo offers as a live Linux distribution. No installation is required, as the operating system loads all necessary data and tools directly from the storage medium. PenToo writes no data to the hard drive and leaves no traces on the host system.

Conclusion: Linux Distributions for Penetration Testing

The market for pentest-focused Linux distributions has become highly differentiated. For every type of security assessment, you will find a distribution that ships with exactly the tools you need. Most distributions also come backed by an active community ready to assist with any issues. To choose the right Linux distribution for your use case, clearly define your requirements and compare them against the available options. With the right distribution in hand, you will be well prepared for your next penetration test!
