Audit log history must be kept for at least 12 months, and at least the latest three months must be ready for immediate analysis. Applies to all entities. The guidance explains that compromises often stay undetected for a long time, and gives storing logs online, archiving them or restoring them quickly from backup as examples of keeping logs immediately available. Customized approach objective: historical activity records can be used straight away to support incident response and are held for at least 12 months.
This control maps to 41 controls across 21 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 10.5.1 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.
