Control: 8 S3 Block Public Access setting should be enabled at the bucket level

Description

This control checks whether S3 buckets have bucket-level public access blocks applied. This control fails if any bucket level public access settings are set to false.

Block Public Access at the S3 bucket level provides controls to ensure that objects never have public access. Public access is granted to buckets and objects through access control lists (ACLs), bucket policies, or both.

Remediation
