Recently, it was adapted to require both a vulnerability scan and a pen test. The vulnerability assessment and penetration test must include the perimeter of the Cardholder Data Environment (CDE) and any systems which, if compromised, could impact the security of the CDE. Penetration tests must be performed at least once annually and every six months for service providers.
Penetration Testing assesses the controls used to protect the CDE for PCI DSS
Specifically, PCI DSS 3.2 distinguishes between a vulnerability scan (Requirement 11.2) and a penetration test (Requirement11.3), both of which are required for PCI DSS compliance. PCI DSS Requirement 188.8.131.52 requires an organization to perform penetration testing on CDE segmentation controls every six months. The PCI Security Standard Council’s guidance states organizations should:
