Kali Linux: what is it, why use it, and how to install it
In today’s article, we will discuss one such stylized operating system: Kali Linux, the default for computer hacking and working with network utilities. As a bonus, a detailed, step-by-step guide on how to install Kali Linux on your machine is also included.
What is Kali Linux?
Kali Linux is a Debian-based Linux distribution aimed at advanced penetration testing and security auditing. Kali contains several hundreds of tools which are geared towards various information security tasks, such as Penetration Testing, Security research, Computer Forensics, and Reverse Engineering. Kali Linux is developed, funded, and maintained by Offensive Security, a leading information security training company.
Why Use Kali Linux?
The operating system is made by penetration testers for pentesters and thus is specifically geared to meet the requirements of professional penetration testing. Here are some of them:
- Network services are disabled by default
- Custom upstream kernel patched for wireless injection
- Minimal and trusted set of repositories
For security reasons, Kali Linux, despite being open-source, is not a wide-open source software, meaning that the development team is small and trusted.
Kali Linux System Requirements
Before installing any software on your PC (or server), you need to know its system requirements and make sure that your device meets them.
- A minimum of 20 GB disk space for the Kali Linux install.
- Minimum 1GBof RAM, 2GB or more are recommended.
- CD-DVD Drive / USB boot support
Although most modern devices would definitely support this OS, it is always better to double-check. Such low system requirements also allow for easy installation within a virtual machine. This is actually recommended even for experienced Linux users (at least until they get used to the software).
