TMA-M365-APP-REGISTRATION

Ensure third-party integrated applications cannot be registered by users

보통레벨 1자동m365

설명

Allowing every user to register applications enables persistence and phishing through attacker-controlled app registrations. Requires an already-connected Microsoft Graph session: Install-Module Microsoft.Graph; Connect-MgGraph -Scopes Policy.Read.All,Directory.Read.All,RoleManagement.Read.Directory (read-only scopes). The audit throws if no session exists.
