Certified Information Systems Security Professional (CISSP) — Question 290

Which of the following is the strongest physical access control?

Answer options

• A. Biometrics, a password, and personal identification number (PIN)
• B. Individual password for each user
• C. Biometrics and badge reader
• D. Biometrics, a password, and badge reader

Correct answer: D

Explanation

The correct answer, D, combines biometrics, a password, and a badge reader, providing multiple layers of security that are difficult to bypass. Option A includes a PIN, but it lacks the effectiveness of a badge reader. Option B offers only individual passwords, which are less secure than the multi-factor approach in D. Option C, while including biometrics, does not offer the added security of a password.
