TMA-AZURE-5.7
Ensure there are between 2 and 3 Subscription Owners
Beschreibung
The Owner role in Azure grants full control over all resources in a subscription, including the ability to assign roles to others. Limit the number of security principals (users, groups, service principals, and managed identities) assigned the Owner role to between 2 and 3. If groups are used, ensure their membership is tightly controlled and regularly reviewed to avoid privilege sprawl.
