Systems Security Certified Practitioner (SSCP) — Question 12

Which of the following is true of two-factor authentication?

Answer options

• A. It uses the RSA public-key signature based on integers with large prime factors.
• B. It requires two measurements of hand geometry.
• C. It does not use single sign-on technology.
• D. It relies on two independent proofs of identity.

Correct answer: D

Explanation

The correct answer is D because two-factor authentication is designed to require two separate proofs of identity to enhance security. Options A and B are incorrect as they do not accurately describe two-factor authentication, and option C, while true, does not define the core principle of this authentication method.
