Which term means not disclosed to unauthorized users?

• A. Traffic Analysis
• B. Confidentiality
• C. Integrity
• D. Availability

Answer: (B)

Protecting information from being disclosed to unauthorized users is the confidentiality aspect of information security. It focuses on preventing sensitive data from slipping to those who shouldn’t see it, using controls like access permissions, authentication, and encryption. In practice, confidentiality means that even if data is intercepted, it remains unreadable without the proper keys or credentials. The other terms address different concerns: integrity ensures data hasn’t been altered, and availability ensures systems and data are accessible when needed. Traffic analysis is a technique attackers use to infer information by observing communication patterns, which can threaten confidentiality but is a separate concept. So, confidentiality is the correct term.
