1.21 Ensure that no custom subscription owner roles are created - Assignable Scope

Information

Subscription ownership should not include permission to create custom owner roles. The principle of least privilege should be followed and only necessary privileges should be assigned instead of allowing full administrative access.

Rationale:

Classic subscription admin roles offer basic access management and include Account Administrator, Service Administrator, and Co-Administrators. It is recommended the least necessary permissions be given initially. Permissions can be added as needed by the account holder. This ensures the account holder cannot perform actions which were not intended.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Using Azure Command Line Interface 2.0

Verify the usage and impact of removing the role identified

Default Value:
