PCI DSS 4.0 7.2.1: 7.2.1 Access control model defined
The entity must define an access control model that governs how access is granted. The model must provide: access that fits what the entity needs for its business and for access; access to data resources and system components based on each user's job classification and functions; and only the least privileges (for example user versus administrator) needed to carry out a job function. The guidance describes typical model elements (the resources to protect, the job functions needing access to them, and the activities each function performs, such as read, write or query), names role-based and attribute-based models as options, and suggests separation of duties as a design consideration. Objective under the customized approach: access requirements are set by job function following the principles of need to know and least privilege.
This control maps to 53 controls across 25 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
NIST-CSF-PR.AA-05 Access permissions, entitlements, and authorizations are defined in a policy, managed, enforced, and reviewed, and incorporate the principles of least privilege and separation of duties
You are reading one control. How much of PCI DSS 4.0 have you already done?
PCI DSS 4.0 7.2.1 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.
