This control checks whether the S3 bucket policy allows sensitive bucket-level or object-level actions from a principal in another AWS account. The control fails if any of the following actions are allowed in the S3 bucket policy for a principal in another AWS account: s3:DeleteBucketPolicy; s3:PutBucketAcl; s3:PutBucketPolicy; s3:PutObjectAcl; and s3:PutEncryptionConfiguration.
