About

In Microsoft Entra ID, permissions to manage resources are assigned using roles. The Global Administrator / Company Administrator is a role that enables users to have access to all administrative features in Entra ID and services that use Entra ID identities like the Microsoft 365 Defender portal, the Microsoft 365 compliance center, Exchange, SharePoint Online, and Skype for Business Online. Adversaries can add users as Global Administrators to maintain access and manage all subscriptions and their settings and resources.
