What is Kali Linux?

Kali Linux is a Debian-based Linux distribution specifically designed for digital forensics and penetration testing. It comes pre-loaded with many tools and programs, making it an indispensable resource for cybersecurity professionals, ethical hackers, and enthusiasts. The name "Kali" is derived from the Hindu goddess of time and change, symbolising the fluid nature of the tools included in the distribution.
 

History of Kali Linux

The journey of Kali Linux began with its predecessor, BackTrack Linux, which was initially released in 2006. BackTrack gained immense popularity due to its wide array of security tools and features. However, in 2013, Kali Linux officially succeeded, bringing improvements, updates, and a more streamlined development process.

Kali Linux is an open-source project that thrives on community contributions and constant updates. The developers, Offensive Security, have consistently refined and expanded the distribution to keep up with the dynamic landscape of cybersecurity.
