What are the four main components of the CIA triad in information security?

The CIA triad is a foundational concept in information security, and it comprises three core components: Confidentiality, Integrity, and Availability. These elements work together to help organizations protect their data and information systems.

Confidentiality ensures that sensitive information is accessible only to those who have the appropriate permissions, thereby protecting it from unauthorized access. Integrity refers to maintaining the accuracy and reliability of data over its lifecycle, ensuring that information remains unaltered except by authorized individuals. Availability guarantees that authorized users have access to information and resources when needed, preventing downtime or disruptions.

The choice that includes Authenticity adds relevance to the triad by emphasizing the importance of verifying the identity of users and the integrity of the data itself. While Authenticity is indeed a significant aspect of information security, it is not part of the original CIA triad. Thus, the correct choice reflects the recognized components of the triad, emphasizing their critical roles in safeguarding information systems against various threats.
