Answer: (A)

The CIA triad represents the three core principles of information security: Confidentiality, Integrity, and Availability. This model serves as a foundational concept for security practices and frameworks.

Confidentiality ensures that sensitive information is accessed only by authorized individuals or systems, protecting the data from unauthorized access. Integrity involves maintaining the accuracy and reliability of the data by preventing unauthorized alterations, ensuring that the information remains trustworthy. Availability guarantees that the information and resources are accessible to authorized users when needed, thus supporting uninterrupted operations.

Understanding these principles helps organizations create robust security policies and strategies to protect their information systems effectively. Each component of the CIA triad interacts with the others, reinforcing a comprehensive approach to security management. Familiarity with the CIA triad is essential for anyone working in information security, as it guides decision-making and the implementation of security measures.
