BlockPublicAcls

Specifies whether Amazon S3 should block public access control lists (ACLs) for buckets in this account. Setting this element to TRUE causes the following behavior:

  • PutBucketAcl and PutObjectAcl calls fail if the specified ACL is public.

  • PUT Object calls fail if the request includes a public ACL.

  • PUT Bucket calls fail if the request includes a public ACL.

Enabling this setting doesn't affect existing policies or ACLs.

This property is not supported for Amazon S3 on Outposts.

Type: Boolean

Required: No

Specifies whether Amazon S3 should block public bucket policies for buckets in this account. Setting this element to TRUE causes Amazon S3 to reject calls to PUT Bucket policy if the specified bucket policy allows public access.

This property is not supported for Amazon S3 on Outposts.

Type: Boolean

IgnorePublicAcls

Specifies whether Amazon S3 should ignore public ACLs for buckets in this account. Setting this element to TRUE causes Amazon S3 to ignore all public ACLs on buckets in this account and any objects that they contain.

Enabling this setting doesn't affect the persistence of any existing ACLs and doesn't prevent new public ACLs from being set.

This property is not supported for Amazon S3 on Outposts.

Type: Boolean

Required: No
