Which CIA triad component corresponds to ensuring availability of information?

• A. Availability
• B. Confidentiality
• C. Integrity
• D. Non-repudiation

Answer: (A)

Availability is the aspect of security that ensures information and services are accessible to authorized users when they need them. It emphasizes uptime, reliable access, and timely delivery of information. To achieve this, organizations implement redundancy, backups, fault tolerance, disaster recovery plans, and proper capacity planning, along with ongoing monitoring and incident response to minimize downtime. In contrast, confidentiality focuses on keeping information secret from unauthorized parties, integrity ensures data remains accurate and unaltered, and non-repudiation guarantees that actions cannot be denied by the parties involved. Since the question specifically asks about keeping information accessible, Availability is the best fit.
