Audit log files must be protected so that individuals cannot modify them. The testing procedure looks at physical segregation, network segregation and/or access control mechanisms as the means. Applies to all entities. The guidance advises protecting logs on the originating systems and wherever else they are stored, and keeping them out of publicly accessible locations, because unprotected logs cannot be relied on after a compromise. Objective under the customized approach: personnel cannot alter stored activity records.
This control maps to 40 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 10.3.2 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.
