Linux Fundamentals Cybersecurity

Linux Fundamentals for Cybersecurity is your next step on the Payload X path after Network Security Fundamentals. Linux runs the majority of the world's servers, and it's the operating system behind nearly every offensive security tool you'll ever use (Kali, Parrot OS, and the terminal itself). This course takes you from "I've never opened a terminal" to comfortably navigating, managing, and starting to harden a Linux system — with every concept tied back to why it matters for security, not just sysadmin trivia.

Each part ends with a short quiz to lock in what you learned before moving to the next topic.
