1.25 Ensure That 'Subscription Entering AAD Directory' and 'Subscription Leaving AAD Directory' Is Set To 'Permit No One'

Information

Users who are set as subscription owners are able to make administrative changes to the subscriptions and move them into and out of Azure Active Directories.

Rationale:

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.

Impact:

Subscriptions will need to have these settings turned off to be moved.

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