CIA Triad stands for which trio of security concepts?

• A. Confidentiality, Integrity, and Availability
• B. Authentication, Integrity, and Availability
• C. Confidentiality, Anonymity, and Availability
• D. Accessibility, Integrity, and Availability

Answer: (A)

The question tests what the CIA Triad represents in information security. The trio stands for confidentiality, integrity, and availability. Confidentiality means keeping information secret from unauthorized people or systems, so only those with permission can access it. Integrity is about data being accurate and unaltered, ensuring that information remains trustworthy and can be validated. Availability ensures that authorized users can access the information and resources they need when they need them, even in the face of failures or attacks.

That’s why the correct trio is the one that includes confidentiality, integrity, and availability. The other options mix in concepts that aren’t part of the standard triad—such as authentication, anonymity, or accessibility—which don’t form the recognized three-key goals of CIA. Understanding these terms helps you see how different security controls map to each goal, like encryption for confidentiality, checksums or digital signatures for integrity, and redundancy or failover for availability.
