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