Operating System is the main system software which is responsible for the flawless working of the machine. Some Operating Systems are designed for some specific purposes. Though we could use them for anything we want to, but they have some special tools or services available feasibly to its users which makes it a good OS for the specific purpose. Like we generally prefer Windows in case of gaming as most of the games are available for windows itself. Likewise, we prefer mac OS for designing related purposes as most of the designing software is easily available for mac and can be used flawlessly. In the same way when we have an OS for Network Security, Digital Forensics, Penetration testing, or Ethical Hacking named Kali Linux. 

Kali Linux is a Debian-derived Linux distribution that is maintained by Offensive Security. It was developed by Mati Aharoni and Devon Kearns. Kali Linux is a specially designed OS for network analysts, Penetration testers, or in simple words, it is for those who work under the umbrella of cybersecurity and analysis. The official website of Kali Linux is It gained its popularity when it was practically used in Mr. Robot Series. It was not designed for general purposes, it is supposed to be used by professionals or by those who know how to operate Linux/Kali.

This will not only save your time of searching on the internet but also will make you use it with ease. However, if you’re a professional penetration tester or studying penetration testing, there’s no better toolkit than Kali Linux. 

Why Kali Linux? 

If you are interested in penetration testing or cybersecurity stuff you need some specific tools to perform some tasks which come pre-installed and settled up in Kali Linux so you may directly use them without doing any configuration.

Kali Linux is just another Debian distribution with a bunch of networking and security tools. It is a weapon to train or defend yourself not to attack anyone. Kali Linux was designed mainly for professionals. It is for those who want to get their hands in Penetration Testing, Cyber Security, or Ethical Hacking. It is a powerful tool and in case, not used properly, it may lead to losses even.
