What is the most common gap auditors find on A3.3.1.1?

Failure duration not recorded with start and end times

PCI DSS v4.0.1 · Appendix A3: Designated Entities Supplemental Validation (DESV)

`A3.3.1.1` Prompt response to critical security control failures

When a critical security control system fails, the failure must be responded to promptly, with processes covering: restoring security functions; identifying and recording the duration (start and end date and time) of the failure; identifying and recording the cause(s), root cause included, and what remediation the root cause requires; working out which security problems came up while the control was down and dealing with them; deciding whether further action is needed because of the failure; implementing controls to stop the cause recurring; and restarting the monitoring of security controls. Related PCI DSS requirements: all twelve. Guidance: documented evidence, for example entries in a problem management system, should back up these processes. Applies only to designated entities. Objective under the customized approach: not eligible for the customized approach; only the defined approach can be used.

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 (Document repository); keep the periodic reviews but log each one as a dated record with a named reviewer.

Common gaps auditors find

Failure duration not recorded with start and end times
Root cause left blank or recorded as 'unknown'
No review of what happened while the control was down
