restrictPublicBuckets
Specifies whether Amazon S3 should restrict public bucket policies for buckets in this account. Setting this element to TRUE
restricts access to buckets with public policies to only Amazon Web Service principals and authorized users within this account.
Enabling this setting doesn't affect previously stored bucket policies, except that public and cross-account access within any public bucket policy, including non-public delegation to specific accounts, is blocked.
This property is not supported for Amazon S3 on Outposts.
