Which term means legitimate users have access?

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

Answer: (B)

The main idea here is ensuring that legitimate users can reach the system and data they need when they need it. Availability is about keeping systems up and accessible to authorized users, including preventing outages and ensuring reliable access through redundancy, backups, and resilient services. This is the best fit because it directly describes the outcome of having access for those who are allowed in. The other terms cover different properties: integrity guards that data remains accurate and unaltered; confidentiality prevents data from being disclosed to unauthorized parties; non-repudiation provides proof of origin and receipt in a communication. While important, they don’t specifically capture the notion of authorized users being able to access resources.
