BackBox Linux is an Ubuntu-based distribution developed to perform penetration tests and security assessments. It is designed to be fast and easy to use. It provides a minimal yet complete desktop environment, thanks to its own software repositories, which are always updated to the latest stable versions of the most often used and best-known ethical hacking tools. The main aim of BackBox is providing an alternative, highly customizable and well performing system. BackBox uses the light window manager Xfce. It includes some of the most used security and analysis Linux tools, aiming for a wide spread of goals, ranging from web application analysis to network analysis, from stress tests to sniffing, also including vulnerability assessment, computer forensic analysis and exploitation. Part of the power of this distribution comes from its Launchpad repository core, constantly updated to the latest stable version of the most known and used ethical hacking tools. The integration and development of new tools in the distribution follows the open source community, particularly the Debian Free Software Guidelines criteria.
