What it detects

This rule flags events where a user is added to administrative roles, specifically Global Administrator or Device Administrator, based on role-target resource IDs. Attackers commonly expand persistence and privilege by granting themselves or others high-impact admin roles. The detection relies on Azure audit log entries that include role management category, an add-member-to-role operation, and the affected role identifiers in the target resources.
