Which term is one of the five pillars of cyber security?

• A. Encryption
• B. Privacy
• C. Access Control
• D. Confidentiality

Answer: (D)

Protecting information from unauthorized disclosure is the essential idea here. In cybersecurity models, one pillar is confidentiality, meaning data should only be accessible to those with permission. Encryption is a technique that helps achieve confidentiality by transforming data into unreadable form for anyone who doesn’t have the key. Access control supports confidentiality by enforcing who can access data, but it’s a mechanism or policy, not the pillar name itself. Privacy relates to how personal data is collected and used, which is important but not the formal pillar label. So the term that is one of the pillars is confidentiality.
