PCI DSS 4.0 10.2.1: 10.2.1 Audit logging enabled on all system components
Audit logging must be switched on and actively recording for every system component and for cardholder data. Applies to all entities. The guidance explains that logs feed alerts and other monitoring tools such as IDS and SIEM and give a history trail for investigating incidents, and it advises storing only essential information in logs because log content is itself sensitive. Customized approach objective: every activity affecting system components and cardholder data leaves a record.
This control maps to 75 controls across 24 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
You are reading one control. How much of PCI DSS 4.0 have you already done?
PCI DSS 4.0 10.2.1 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.
