PCI DSS 4.0 5.2.1: 5.2.1 Anti-malware deployed on all system components
An anti-malware solution (one or more) must be installed on every system component, with the only exception being components that the periodic evaluations under Requirement 5.2.3 have concluded are not at risk from malware. A component counts as affected by malware when real-world active exploits exist for it, not merely theoretical ones. Applicability: applies to every entity in scope, with no special notes. Customized approach objective: automated mechanisms stop systems from turning into a route for malware attacks.
This control maps to 73 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 5.2.1 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.
