ISACA CISA: Authentication as MOST important feature of access control software

Learn why authentication is the most important feature of access control software and how it differs from identification, violation reporting, and nonrepudiation.

Question

Which of the following is the MOST important feature of access control software?

A. Identification
B. Authentication
C. Violation reporting
D. Nonrepudiation

Answer

B. Authentication

Explanation

Authentication is the process of verifying the identity of a user or system who requests access to a resource. It is the most important feature of access control software, as it ensures that only authorized and legitimate users can access the protected resources.

Identification is the process of presenting an identity to the system, such as a username or a card number, but it does not verify the validity of the identity.

Violation reporting is the process of logging and notifying any unauthorized or suspicious access attempts, but it does not prevent them from happening. Nonrepudiation is the process of ensuring that the origin and integrity of a message or transaction cannot be denied by the sender or the receiver, but it does not relate to the access control software itself.
