Answer & Solution
Correct answer: A. Confidentiality, Integrity, Availability
1. CIA TRIAD is the foundational model of information security.
2. CONFIDENTIALITY: only authorised parties can read data (achieved via encryption, access control).
3. INTEGRITY: data is accurate and unaltered (achieved via hashing, digital signatures, version control).
4. AVAILABILITY: data and systems are accessible when needed (achieved via redundancy, DDoS protection, backups).
5. Every security control maps to one or more of these three pillars.
