Which term is NOT a core component of the CIA triad?

• A. Authenticity
• B. Confidentiality
• C. Integrity
• D. Availability

Answer: (A)

The main concept is recognizing which terms belong to the CIA triad. The three core components are confidentiality, integrity, and availability. Confidentiality aims to keep information secret from unauthorized parties, typically through encryption and access controls. Integrity ensures information remains accurate and unmodified, using mechanisms like hashes, checksums, and digital signatures. Availability guarantees that authorized users can access data and services when needed, supported by redundant systems, backups, and reliable networks. Authenticity, while important in security, deals with confirming the identity of users or the origin of information. It answers whether someone or something is truly who or what it claims to be, and is addressed by authentication methods, digital signatures, and trust verification rather than by the three CIA goals themselves. Therefore, authenticity is not part of the CIA triad.
