Control: 2.14 Ensure That 'Users Can Register Applications' Is Set to 'No'

Description

Require administrators or appropriately delegated users to register third-party applications.

It is recommended to only allow an administrator to register custom-developed applications. This ensures that the application undergoes a formal security review and approval process prior to exposing Microsoft Entra ID data. Certain users like developers or other high-request users may also be delegated permissions to prevent them from waiting on an administrative user. Your organization should review your policies and decide your needs.

Remediation

From Azure Portal

From Azure Home select the Portal Menu.
Select Microsoft Entra ID.
Under Manage, select Users.
Under Manage, select User settings.
Set Users can register applications to No.
Click Save.

From PowerShell

$param = @{ AllowedToCreateApps = "$false" }
Update-MgPolicyAuthorizationPolicy -DefaultUserRolePermissions $param

Default Value

By default, Users can register applications is set to "Yes".
