Storage Bucket All Users Policy

Ensures Storage bucket policies do not allow global write, delete, or read permissions

Storage buckets can be configured to allow the global principal to access the bucket via the bucket policy. This policy should be restricted only to known users or accounts.

Ensure that each storage bucket is configured so that no member is set to allUsers or allAuthenticatedUsers.
