Control: 1.25 Ensure fewer than 5 users have global administrator assignment

Description

Users who are set as subscription owners are able to make administrative changes to the subscriptions and move them into and out of Microsoft Entra ID.

Permissions to move subscriptions in and out of Azure Active Directory must only be given to appropriate administrative personnel. A subscription that is moved into an Azure Active Directory may be within a folder to which other users have elevated permissions. This prevents loss of data or unapproved changes of the objects within by potential bad actors.

Remediation

From Azure Portal

From the Azure Portal Home select the portal menu.
Select Subscriptions.
Select Manage Policies.
Under Subscription leaving AAD directory and Subscription entering AAD directory select Permit no one.

Default Value

By default Subscription leaving Microsoft Entra ID directory and Subscription entering Microsoft Entra ID directory are set to Allow everyone (default)
