PCI DSS 7.2.5: Assign Least Privilege for System Accounts
System account proliferation and over-privileged access are leading causes of data breaches in payment environments. PCI DSS 7.2.5 requires organizations to grant only the minimum access necessary for each application and system account to function. Implementing least privilege reduces your attack surface and strengthens your overall security posture.
What this means
This control mandates that every application and system account receives access privileges strictly limited to what's necessary for its specific function. Rather than granting broad administrative or user-level access by default, least privilege follows the principle of minimum necessary access. This includes limiting database accounts, service accounts, administrative accounts, and application user accounts to their defined roles and responsibilities. Any access beyond what's required for normal operations creates unnecessary risk.
How to comply
- 1.Conduct a comprehensive inventory of all application and system accounts across your environment
- 2.Document the specific functions and access requirements for each account
- 3.Remove unnecessary privileges from existing accounts and reset them to baseline least privilege levels
- 4.Implement role-based access control (RBAC) to automatically assign privileges based on job function
- 5.Establish a process for reviewing and re-certifying account privileges at least annually
- 6.Disable or remove unused and default accounts that don't require active access
- 7.Monitor account usage and access patterns to identify and remediate privilege creep
- 8.Enforce separation of duties to prevent single accounts from having conflicting access
Evidence auditors look for
- Account privilege documentation showing defined access levels for each system account
- RBAC configuration files or access control matrices defining role-to-privilege mappings
- Annual access review sign-offs confirming privileges remain appropriate and necessary
- Disabled or removed account records for deprecated or unused accounts
- Access logs demonstrating accounts operate only within their assigned privilege scope
- Change management records showing privilege modifications and approvals
