PCI DSS 7.3.1: Implement Role-Based Access Control System

What this means

Role-based access control (RBAC) is an access management strategy that restricts system and data access based on a user's defined role and business function. Instead of granting individual permissions to each person, you assign users to roles (e.g., accountant, manager, developer) and each role has predefined access rights. This ensures users can only access the systems and data necessary for their job, following the principle of least privilege. RBAC reduces the risk of unauthorized access, data exposure, and insider threats while simplifying access administration at scale.

How to comply

1. 1.Identify all user roles within your organization based on job functions and business needs (e.g., admin, operator, auditor, user).
2. 2.Map each role to specific system components, applications, and data they require to perform their duties.
3. 3.Define granular permissions for each role: what systems they can access, what actions they can perform, and what data they can view or modify.
4. 4.Implement RBAC in your access control system (directory service, identity provider, or application-level controls).
5. 5.Assign users to roles based on their job responsibilities; avoid granting individual ad-hoc permissions.
6. 6.Document all roles, their assigned permissions, and the business justification for each.
7. 7.Review and validate RBAC configuration to ensure it enforces least privilege—no user has more access than required.
8. 8.Test role-based access controls to confirm users can only access assigned resources and cannot escalate privileges.
9. 9.Conduct quarterly access reviews to recertify roles and remove unnecessary permissions.
10. 10.Revoke all access immediately when users change roles or leave the organization.

Evidence auditors look for

• Documented role inventory with defined permissions matrix showing which roles access which systems and data.
• Active Directory, Okta, or similar identity management system configured with role-based group membership.
• Configuration screenshots showing role definitions and permission assignments in your systems (databases, applications, file servers).
• User-to-role assignment list showing each employee's role and assigned access rights.
• Access control policy documentation detailing how roles are created, assigned, reviewed, and removed.
• Quarterly access review sign-offs by management certifying role assignments are still appropriate.
• Testing evidence (logs, screenshots) demonstrating users cannot access systems outside their role.
• Change management records showing approval and implementation of new roles or permission changes.
• Deprovisioning evidence showing immediate access revocation when users change roles or terminate employment.
