• B. Confidentiality, Integrity, and Availability
• C. Context, Impact, and Authorization
• D. Compliance, Innovation, and Assurance

Answer: (B)

The CIA triad is foundational to understanding and implementing security measures in information technology. The correct answer emphasizes three crucial principles: Confidentiality, Integrity, and Availability.

Confidentiality ensures that sensitive information is accessed only by authorized individuals. This principle protects data from unauthorized access and disclosure, maintaining privacy and trust.

Integrity involves maintaining the accuracy and reliability of data. It ensures that information remains unaltered during storage and transmission unless done by authorized entities, thus protecting it from unauthorized modification.

Availability signifies that information and resources are accessible to authorized users when needed. This principle is essential for ensuring that services and data are up and running without interruption, thus supporting business operations.

Each of these principles plays a vital role in establishing a robust security posture. Their combination helps organizations safeguard information effectively while ensuring compliance with various regulations and frameworks.
