Availability in CIA is about ensuring what?

• A. The guarantee that a computer system is available or accessible by an authorized user whenever needed; maintaining data accessibility
• B. Preventing data loss
• C. Encrypting data in transit
• D. Ensuring hardware redundancy

Answer: (A)

Availability means making sure that authorized users can access the system and its data whenever they need to. It’s about uptime, reliable performance, and quick recovery from outages so services aren’t unavailable when requested. This includes having solid backups, redundant components, disaster recovery plans, and active monitoring to prevent or quickly recover from failures. While protecting data with encryption or preventing data loss are important, they cover confidentiality and integrity aspects, not the core idea of being able to access the system and information when required. Hardware redundancy helps availability, but the main concept is the ability for legitimate users to reach the resources they need without undue delay.
