Overview of Permission Control

An OBS bucket belongs to a specific account. The OBS performs permission verification on each access request received, in order to ensure that the bucket and object can be accessed only by authorized users. You can control requesters' permissions to access requested resources (buckets or objects). Requesters can only access resources after being granted permissions.

A bucket or object is created by a user who is the owner of the bucket or object. By default, only the owner has the permission to access the bucket or object. To access the bucket or object, other users must obtain the access permission of the bucket or object. The owner can manage permissions for the bucket or object using the ACL or bucket policy.
