What is the purpose of vulnerability scanning in PCI DSS compliance?
- A.To record the open ports on CDE hosts and document that unused services were removed as the standard requires
- B.To simulate an attacker exploiting weaknesses in the CDE and demonstrate real compromise so the results can drive segmentation changes
- C.To identify known security vulnerabilities in systems and applications so they can be remediated before exploitation
- D.To verify that cardholder data is encrypted on disk and in transit so the assessor can confirm the cryptography requirements are met
Why C is correct
Vulnerability scanning systematically identifies known security weaknesses in systems, networks, and applications, enabling organizations to remediate them before attackers can exploit them.
