Ensure the GA role is not added as a local administrator during Entra join

中レベル 1手動レビューm365

説明

This setting controls whether the Global Administrator role is automatically added to the local administrators group on a device during the Microsoft Entra join process. The recommended state is No. System administrators may be inclined to use over-privileged accounts for convenience when managing devices. Enforcing this control helps discourage that behavior by requiring administrative actions to be performed using accounts specifically designated for local administration. This promotes adherence to the principle of least privilege and reduces the risk associated with using high-level roles for routine tasks. For example, using a Global Administrator account to authenticate to a compromised endpoint and continue performing tasks significantly increases the risk of broader organizational compromise.
