Certified Data Privacy Solutions Engineer (CDPSE) — Question 144

Which of the following is the BEST control to mitigate the impact of credential harvesting attacks?

Answer options

• A. Vulnerability scanning
• B. Role-based access control (RBAC)
• C. Encryption of network traffic
• D. Multi-factor authentication (MFA)

Correct answer: D

Explanation

Multi-factor authentication (MFA) significantly enhances security by requiring multiple forms of verification, making it much harder for attackers to misuse stolen credentials. In contrast, vulnerability scanning identifies potential security weaknesses, RBAC restricts access based on roles, and encryption protects data in transit, but none of these directly prevent the exploitation of harvested credentials like MFA does.
