What it checks
Subscription-level role assignments grant broad permissions across all resources within a subscription. Overly permissive or stale assignments at this scope can allow lateral movement and unauthorized access to sensitive workloads. Regular audits ensure that only authorized personnel retain subscription-wide privileges.
Recommended value
Minimize subscription-level role assignments; prefer resource group or resource-level scoping
Remediation
Review all subscription-level role assignments in Azure IAM and remove any that are stale, unnecessary, or overly broad. Reassign permissions at the resource group or individual resource level where possible. Implement a recurring quarterly access review using Azure AD Access Reviews for subscription-scoped roles.
