What is Kali Linux?
Kali Linux is a Debian-based Linux distribution designed for advanced penetration testing and security auditing. It is maintained and funded by Offensive Security Ltd. It was developed by Mati Aharoni and Devon Kearns of Offensive Security through the rewrite of BackTrack, their previous forensics Linux distribution.
Kali Linux comes pre-loaded with a wide range of penetration testing tools, including tools for information gathering, vulnerability analysis, wireless attacks, web application testing, password attacks, and more. It is widely used by cybersecurity professionals, ethical hackers, and security researchers to assess the security of computer systems and networks.
Because of its powerful suite of tools, Kali Linux is not recommended for casual or novice users. It’s intended for professionals who have a strong understanding of network security and penetration testing techniques.
It’s important to note that while Kali Linux is a powerful tool for cybersecurity professionals, using it for any unauthorized or malicious activities is strictly illegal and unethical. It should only be used in ethical hacking and security testing scenarios with proper authorization.

Installing Kali Linux on Virtualbox
Kali Linux is a completely free and open-source operating system, developed and maintained by Offensive Security as a powerful platform for cybersecurity professionals, ethical hackers, and penetration testers. Since it is distributed under an open-source license, you can legally download it at no cost directly from the official Kali Linux website (https://www.kali.org).
The official website provides multiple download options, including pre-built images for various platforms such as VMware, VirtualBox, bare-metal installations, ARM devices (like Raspberry Pi), and even cloud platforms. Additionally, Kali Linux offers different flavors—such as the lightweight ‘Kali Linux Light’ or specialized versions with different desktop environments—to suit your specific needs.
By downloading Kali Linux from the official source, you ensure that you receive a secure, unmodified, and up-to-date version of the OS, free from malware or unauthorized alterations. Always verify the integrity of your download using the provided checksums or GPG signatures to guarantee authenticity before installation.
You can either burn downloaded ISO file into a DVD / USB and then use that device to install Kali Linux on your Data center servers.
