1.25 Set 'Subscription Entering Azure Active Directory (AAD) Directory' and 'Subscription Leaving AAD Directory' To 'Permit No One' (Manual)

Profile Applicability

• Level 2

Description

Users 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.

Audit

From Azure Portal

1. From the Azure Portal Home select the portal menu in the top left.
2. In the column that opens up select General and then Subscriptions within the page that opens up.
3. Select Manage policies and in the screen that opens verify that Subscription leaving AAD directory and Subscription entering AAD directory is set to Permit no-one

Remediation

From Azure Portal

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