NEW QUESTION # 187
Which of the following is NOT an essential security principle?
- A. Confidentiality
- B. Integrity
- C. Availability
- D. Complexity
Answer: D
Explanation:
Complexity is not considered an essential security principle. The essential security principles are confidentiality, availability, and integrity. Confidentiality ensures that information is only accessible to authorized individuals or entities. It focuses on protecting sensitive data from unauthorized disclosure or access. Availability ensures that information and resources are accessible when needed. It emphasizes the need for systems and networks to be operational and usable, with minimal downtime or interruptions. Integrity ensures that information is accurate, complete, and unaltered. It focuses on maintaining the trustworthiness and reliability of data and preventing unauthorized modifications. Complexity, although important in certain areas of cybersecurity, is not considered an essential security principle on its own. It often relates to the design and implementation of security controls or measures, rather than being a fundamental principle.
