Many individuals believe that Kali is a hacking or cracking programme for social media accounts or web servers. This is one of the most common misconceptions regarding Kali Linux. Kali Linux is simply another Debian distribution that includes a number of networking and security tools. It is a weapon for training or self-defense, not for attacking others.

Kali Linux was created primarily for professionals. It has been created for anyone interested in Penetration Testing, Cyber Security, or Ethical Hacking. It is a powerful tool that, if not used properly, can result in losses.

In other words, if you are familiar with Linux and its terminal commands, architecture, system, and file management, you will be OK with Kali Linux. And if you aren’t, we suggest that you start with the Ubuntu distribution to learn about Linux, and then give Kali Linux a shot after some practise.
