Object Ownership Configuration

Object Ownership Overview

S3 Object Ownership is a feature in Amazon S3 that enables you to manage the ownership of objects uploaded to your bucket and and to disable or enable access control lists (ACLs).

By default, Object Ownership is set to "Bucket owner enforced", and ACLs are disabled.

With ACLs disabled, the bucket owner becomes the exclusive owner of all objects in the bucket, managing data access through access management policies.

How to configure Object Ownership

1. Select the bucket you want to configure Object Ownership for and click:

   Buckets, Object Ownership Configuration..:

   

   The Object Ownership Configuration dialog will open:

   

   Bucket owner enforced - ACLs are disabled, and the bucket owner automatically owns and has full control over every object in the bucket. ACLs no longer affect permissions to data in the S3 bucket. The bucket uses policies to define access control.

   Bucket owner preferred - The bucket owner owns and has full control over new objects that other accounts write to the bucket with the bucket-owner-full-control canned ACL.

   Object writer - The AWS account that uploads an object owns the object, has full control over it, and can grant other users access to it through ACLs.

2. Select the desired ownership configuration and click OK.
