2.24 Ensure a Custom Role is Assigned Permissions for Administering Resource Locks
Warning! Audit Deprecated
This audit has been deprecated and will be removed in a future update.
View Next Audit VersionInformation
Resource locking is a powerful protection mechanism that can prevent inadvertent modification/deletion of resources within Azure subscriptions/Resource Groups and is a recommended NIST configuration.Rationale:
Given the resource lock functionality is outside of standard Role Based Access Control(RBAC), it would be prudent to create a resource lock administrator role to prevent inadvertent unlocking of resources.
Impact:
By adding this role, specific permissions may be granted for managing just resource locks rather than needing to provide the wide Owner or User Access Administrator role, reducing the risk of the user being able to do unintentional damage.
NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.
