What is the CIA triad in information security?

Correct answer: Confidentiality, Integrity, and Availability

Option A is correct because the CIA triad is the foundational model of information security, representing Confidentiality (protecting data from unauthorized disclosure), Integrity (ensuring data is accurate and unaltered), and Availability (ensuring systems and data are accessible when needed). Option B is incorrect because Classification, Identification, and Authorization describe access control concepts, not the CIA triad. Option C is incorrect because Cryptography, Internet, and Access are individual security mechanisms, not the three pillars of the triad. Option D is incorrect because Compliance, Inspection, and Audit relate to governance and oversight activities, not the core security properties defined by the triad.
