Kali Linux is referred to as a “Professional Penetration-Testing Distribution” which was released in 2013.
Some key features about this operating system (O.S.), in addition to the large number of tools Kali comes bundled with, include:
- FHS compliant – adheres to the Filesystem Hierarchy Standard which helps support interoperability of applications, system administration tools, development tools, and scripts as well as greater uniformity of documentation.
- Wide-ranging wireless device support – built to support as many wireless devices as possible, allowing it to run properly on a wide variety of hardware and making it compatible with numerous USB and other wireless devices.
- ARMEL & ARMHF support – works on ARM-based single-board systems like Raspberry Pi which are becoming more prevalent and inexpensive.
Kali is based on a rebuild of BackTrack Linux which had ‘root’ as the default user. From early 2020 this was changed to ‘kali’ user for security purposes.
