Phase 1 · Cybersecurity Foundations
TopicsCIA Triad (Confidentiality, Integrity, Availability)
Part of the Cybersecurity Roadmap.
Summary
The foundational model for security goals — Confidentiality (only authorized access), Integrity (data isn't tampered with), Availability (systems stay usable) — every security control exists to protect one or more of these.
How to Learn This
- 1Classify 5 real security controls (encryption, backups, access control) by which CIA element they primarily protect.
- 2Identify a real incident type that primarily violates availability (e.g. a DDoS attack) versus confidentiality (e.g. a data breach).
- 3Learn why some controls trade off against each other — extreme confidentiality controls can hurt availability.
