Control: 2.1.2 Ensure S3 Bucket Policy allows HTTPS requests


Amazon S3 provides multiple encryption options to protect data at rest, transit & it's access. At the Amazon S3 bucket level, you can restrict bucket policy making the objects accessible only through HTTPS.

By default, Amazon S3 allows both HTTP and HTTPS requests. To achieve only allowing access to Amazon S3 objects through HTTPS you also have to explicitly deny access to HTTP requests. Bucket policies that allow HTTPS requests without explicitly denying HTTP requests will not comply with this recommendation.
