10.7.2 Detect and alert on critical security control failures

When a critical security control system fails, the failure must be detected, alerted and addressed promptly, covering at least failures of: IDS/IPS; network security controls; anti-malware; change-detection tools; logical access controls; physical access controls; segmentation controls where used; audit logging mechanisms; mechanisms for reviewing audit logs; and any automated security testing tools in use. Applies to all entities, service providers included. Applicability: takes the place of 10.7.1 from 31 March 2025 and adds two control systems that 10.7.1 did not list (the mechanisms for reviewing audit logs and automated security testing tools). Objective under the customized approach: any failure of a critical security control system is spotted and dealt with promptly. Future-dated: treated as a best practice up to 31 March 2025 and mandatory since then.

Source: PCI DSS v4.0.1, 10.7.2. The statement above is our statement of the clause, read from the published text and cited so you can check it against the official text, not the instrument verbatim. Open PCI DSS v4.0.1 in the compliance library.

Version 4.0.1 is the active version; 4.0 has been retired. Appendix A1 applies only to multi-tenant service providers, A2 only to card-present POS POI terminals that still use SSL or early TLS, and A3 only when a payment brand or acquirer requires it. Which requirements apply to you follows your validation type.

where the evidence lives
teal = a system already holds it · olive = produced at each review. To go live: easy when half or more of the artefacts are already held by a system, moderate from a quarter to a half, hard below a quarter.

These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

First move

Start with the 2 of 5 artefacts that already live in a system (SIEM / log platform); keep the periodic reviews but log each one as a dated record with a named reviewer.
