Introduction to Linux Distributions (Distros)

Cyber Security Mastery: From Zero to Hero

What is a Linux Distribution?

Linux is just the kernel (the core operating system engine). A Linux Distribution (or 'Distro') packages the kernel with a set of user applications, system utilities, and a desktop environment.

Common General-Purpose Distros

  1. Ubuntu: Very user-friendly, great for servers and desktops. Based on Debian.
  2. Fedora: Community-supported distribution sponsored by Red Hat. Known for bleeding-edge software.
  3. Debian: The foundation for many other distros (including Ubuntu and Kali). Known for stability.

Security-Focused Distros

These come pre-loaded with hundreds of security tools, saving significant setup time:

  1. Kali Linux (The OS of Choice): Derived from Debian, maintained by Offensive Security. The industry standard for penetration testing.
  2. Parrot OS: Based on Debian, often considered more resource-light than Kali, with strong focus on forensics and privacy.

Action Item: For this course, our primary offensive platform will be Kali Linux.
