// Introduction to Cyber Security
Most cyber security courses hand you a pile of definitions and hope something sticks. This one doesn't. Instead, you follow a single company — a small clinic called Northwind — from the moment an attacker first searches for them, all the way to the breach notification letter. Every lesson is one step of that attack, shown from both sides: what the attacker did, and what the defenders saw (or completely missed). You will learn what reconnaissance, phishing, privilege escalation, lateral movement and ransomware actually mean — not as vocabulary, but as things you watched happen. By the end you will understand how real attacks unfold, and you will finish by locking down your own accounts using exactly what you learned. Written for complete beginners. No coding, no command line, no prior IT knowledge required. If you do not yet know what cyber security is, this is the right place to start. This foundation course is free.
