Which statement defines Confidentiality in the CIA triad?

• A. Encrypting data at rest.
• B. Maintaining data accuracy.
• C. Only authorized people view information.
• D. Ensuring data is always available.

Answer: (C)

Confidentiality is about who can access information. It aims to prevent unauthorized disclosure, so keeping data viewable only by those with permission is the core idea. That’s why “Only authorized people view information” matches confidentiality perfectly. The other options point to other aspects of the CIA triad: encryption at rest is a tactic to protect confidentiality, but it’s not the definition itself; maintaining data accuracy relates to integrity; and making sure data is always available relates to availability.
