Certified Information Systems Auditor (CISA) — Question 646

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

Answer options

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

Correct answer: B

Explanation

Authentication is the most critical feature of access control software as it ensures that users are who they claim to be before granting access. Without proper authentication, even if identification is correct, unauthorized users could gain access. Violation reporting and nonrepudiation are important but secondary to the fundamental need for authentication.
