Relationship Between Bucket ACLs and Bucket Policies

Unlike access control lists (ACLs), which can add (grant) permissions only on individual objects, policies can either add or deny permissions across all (or a subset) of objects within a bucket.

If a bucket ACL and a bucket policy are used at the same time and their authorization conflicts, the bucket policy prevails.
