Confidentiality in CIA is defined as?

• A. Protect information so unauthorized users cannot access it
• B. Ensure data backups
• C. Guarantee system uptime
• D. Encrypt all data at rest

Answer: (A)

Confidentiality is the protection of information from being disclosed to people who do not have permission to see it. It’s about access control and preventing unauthorized viewing or sharing. The best choice states protecting information so unauthorized users cannot access it, which directly describes preventing disclosure. Data backups relate to data resilience and recovery (integrity and availability), not secrecy. Guaranteeing system uptime is about availability. Encrypting all data at rest is a common technique to protect confidentiality, but confidentiality itself is the idea of preventing unauthorized access, with encryption being a method used to achieve that.
