Kali Linux is a Debian-derived Linux distribution designed for penetration testing. With over 600 preinstalled penetration-testing programs, it earned a reputation as one of the best-operating systems used for security testing. As a security-testing platform, it is best to install Kali as a VM on VirtualBox.
Kali has a rolling release model, ensuring up-to-date tools on your system. Also, there is an active community of users providing ongoing support.
Since these instructions take you through the installation process in a virtual environment, you need to ensure you have one set up on your system. In this article, we are using VirtualBox, as it is a simple to use, open-source virtualization solution.
On the official Kali Linux website downloads section, you can find Kali Linux .iso images. These images are uploaded every few months, providing the latest official releases.
Navigate to the Kali Linux Downloads page and find the packages available for download. Depending on the system you have, download the 64-Bit or 32-Bit version.
