The entity must define, document and implement a penetration testing methodology that includes: industry-accepted testing approaches; coverage of critical systems and of the entire CDE perimeter; tests run from both outside and inside the network; tests validating any scope-reduction and segmentation controls; tests at the application layer that find at least the vulnerability types listed under Requirement 6.2.4; tests at the network layer covering every component supporting network functions plus operating systems; a review of the threats and vulnerabilities the entity met over the past 12 months; a documented approach for assessing and addressing risk from exploitable vulnerabilities and weaknesses the testing finds; and keeping the results of testing and of remediation for a minimum of 12 months. Applicability: internal testing means testing within the CDE and into it from trusted and untrusted internal networks; external testing means testing the exposed outer edge of trusted networks, and of critical systems that are reachable from or connected to public network infrastructure. Objective under the customized approach: a formal methodology exists for thorough technical testing in which a competent manual attacker tries to exploit vulnerabilities and weaknesses through simulated attacks.
This control maps to 54 controls across 22 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
PCI DSS 4.0 11.4.1 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of PCI DSS 4.0 your existing evidence covers. Hold ISO 27001:2022 and 139 of 280 PCI DSS 4.0 controls already carry evidence.
Each report names every control your existing framework evidences, every one it does not, the reasoning behind each claim, and the claims that were argued against and rejected. 415 were rejected on the ISO 27001:2022 pair alone.
The graph holds this control, the 54 it maps to, and the evidence behind each claim, over MCP and REST.
