Qué comprueba
Guest or external users with privileged Entra ID role assignments present a significant supply chain and third-party risk. These accounts originate from external organizations and are not subject to the same security controls, password policies, or monitoring as internal accounts. A compromised guest account with administrative privileges can lead to full tenant compromise while being difficult to detect through normal internal security monitoring
Valor recomendado
No guest or external users assigned to any privileged Entra ID roles
Remediación
Review all privileged role assignments and identify any members with a userType of Guest. Remove privileged role assignments from all guest accounts immediately. If external administrative access is required, provision dedicated cloud-only accounts within the tenant under full organizational control instead of using guest invitations
