Managing access to an Amazon S3 on Outposts bucket using a bucket policy

A bucket policy is a resource-based AWS Identity and Access Management (IAM) policy that you can use to grant access permissions to your bucket and the objects in it. Only the bucket owner can associate a policy with a bucket. The permissions attached to the bucket apply to all of the objects in the bucket that are owned by the bucket owner. Bucket policies are limited to 20 KB in size. For more information, see Bucket policy.

You can update your bucket policy to manage access to your Amazon S3 on Outposts bucket. For more information, see the following topics.
