Reworked, connection-first notes - same exam scope as the original Cybersecurity course, rewritten to explain concepts and their connections. The mandatory readings are included.
How to use these lessons
Each lesson is built from the slides, the Stallings textbook chapter, the hands-on tutorials, and real past exam questions.
Lessons stay within the 2025/26 exam scope (Chapters 1–3; Access Control / Ch.4 is out of scope this year).
Most lessons end with a Past exam questions practice section. Study material, not an official source.
