How is authentication related to the CIA triad

Question

Which component(s) of the CIA triad, Confidentiality, Integrity, or Availability, does authentication primarily support, and how?

Answer 1

Authentication is a fundamental component of the Confidentiality aspect of the CIA triad. By verifying the identity of users or systems, authentication ensures that only authorized individuals can access sensitive information, thereby maintaining its confidentiality.

While authentication is primarily associated with confidentiality, it also plays a crucial role in Integrity. By confirming the identity of users, authentication helps ensure that only authorized individuals can modify data, thereby preserving its integrity.

In summary, authentication is essential for both confidentiality and integrity within the CIA triad, as it controls access to sensitive information and ensures that only authorized users can alter data.
