CompTIA Security+ (SY0-601) — Question 764

A security engineer was assigned to implement a solution to prevent attackers from gaining access by pretending to be authorized users. Which of the following technologies meets the requirement?

Answer options

• A. SSO
• B. IDS
• C. MFA
• D. TPM

Correct answer: C

Explanation

MFA (Multi-Factor Authentication) is the correct answer as it requires multiple forms of verification, making it difficult for attackers to impersonate authorized users. SSO (Single Sign-On) simplifies user authentication but does not add additional security layers. IDS (Intrusion Detection System) monitors for unauthorized access but does not prevent it, and TPM (Trusted Platform Module) is focused on hardware security rather than user authentication.
