1.Penguin Landscape

One of the most-used Linux distros is Kali Linux, which is preferred by security professionals.

If you're disillusioned with Windows, Linux is probably the top alternative. While it has been around since the 90s, you might not have used any of its implementations or distributions (distros). Kali Linux is one such popular distro used primarily for cybersecurity. It might not be geared toward the average Linux user, but if you're a professional penetration tester or studying cybersecurity with an aim to get certified, Kali Linux is one of the best tools available.

People are attracted to Linux thanks to its stability, security, and open-source nature. Unlike mainstream operating systems like Windows, Linux is much faster, too, simply because it's more lightweight. However, you don't access Linux with just "Linux." Distros are specific implementations of the Linux kernel, and these are what people use when they talk about installing Linux.

Kali Linux itself is derived from Debian, one of the oldest and most popular Linux distros. It was initially designed in 2013 for penetration testing and security analysis. Like most distros, it's an open-source project. It's developed and maintained by Offensive Security, and for the purposes of keeping it secure, only the packages signed off by the development team are officially approved. This is partly the reason the average Linux user might prefer Ubuntu, Linux Mint, or other distros instead.
