Failures of critical security control systems must be detected, alerted on and addressed promptly, covering, as a minimum, failures of: IDS/IPS; network security controls; anti-malware solutions; FIM; logical access controls; physical access controls; any segmentation controls in use; audit logging mechanisms; tools that automatically review audit logs; and tools that automatically review code, where used. Related PCI DSS requirements: all twelve. Guidance: a typical failure is a control stopping or not working as intended, such as a firewall losing its rules or going offline. Applies only to designated entities. Objective under the customized approach: not eligible for the customized approach; only the defined approach can be used. Future-dated (bullets on automated audit log review mechanisms and on automated code review tools, where used): treated as a best practice up to 31 March 2025 and mandatory since then; the other bullets are already required.
PCI DSS 4.0 A3.3.1 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 0 it maps to, and the evidence behind each claim, over MCP and REST.
