TMA-M365-GLOBAL-ADMIN-COUNT
Ensure between two and four Global Administrators are designated
高レベル 1自動m365
説明
At least two Global Administrators avoid lock-out; more than four widens the attack surface. Counts active members of the Global Administrator role. 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.
