PCI DSS 4.0 6.3.3: 6.3.3 Timely installation of security patches
All system components must be shielded from known vulnerabilities by applying relevant security patches or updates such that: patches or updates addressing critical vulnerabilities, as ranked under Requirement 6.3.1, must go in within one month of their release; and every other relevant security patch or update is installed within a suitable time frame set by the entity's own assessment of how critical the risk is to its environment, using the Requirement 6.3.1 ranking process. It applies to all entities and all system components. Customized approach objective: exploitation of a known vulnerability cannot be used to compromise system components.
This control maps to 72 controls across 27 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 6.3.3 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.
