CIA stands for?

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

Answer: (C)

The CIA triad is a foundational model in information security. It highlights three key properties to protect information and systems: Confidentiality means information is accessible only to those authorized to see it, protected by measures like encryption and access controls. Integrity means information and systems remain accurate and have not been tampered with, supported by checks, digital signatures, and proper change control. Availability means that authorized users can access data and services whenever needed, ensured by reliable infrastructure, backups, and redundancy. This trio—Confidentiality, Integrity, Availability—captures the essential goals of protecting data in most security contexts. Other options mix in concepts that aren’t part of the standard triad. Privacy is a broader data-protection principle, not the triad’s specific trio. Accessibility isn’t the term used in the model (the correct term is Availability). Authentication focuses on proving identity, not a property of information itself, and it isn’t part of the three named attributes in the triad.
