Ensure local administrator assignment is limited during Entra join
Description
This setting determines if the Microsoft Entra user registering their device as Microsoft Entra join will be added to the local administrators group. This setting applies only once during the actual registration of the device as Microsoft Entra join. The recommended state is Selected or None. To uphold the principle of least privilege, the assignment of local administrator rights during Microsoft Entra join should be centrally managed using appropriate built-in roles through Intune. This approach minimizes the number of disparate users with elevated privileges, reducing the attack surface and potential for misuse. Centralized management also streamlines the deprovisioning process, ensuring that administrative access can be revoked efficiently and consistently across all devices, rather than requiring manual intervention on each individual endpoint.
