Ensure users cannot register applications

中レベル 1手動レビューm365

説明

This setting controls whether standard users can register applications in the Microsoft Entra ID directory. When enabled, any user can create app registrations, which function as identity objects for applications. Allowing standard users to create app registrations expands the tenant's attack surface. A compromised account or malicious insider could create a rogue app registration to establish a persistent OAuth client, facilitate token theft, or impersonate a legitimate application. Restricting app registration to privileged roles ensures that new application identities in the directory are subject to administrative review and approval before they can be granted permissions to organizational resources.
