Force SSL on Amazon S3

Question

Is it possible (via IAM, bucket policy, or otherwise) to force Amazon S3 to only serve content over HTTPS/SSL and deny all regular, unencrypted HTTP access?

Answer 1

Here you allow your incoming traffic but refuse the non SSL one. If you want to go back just remove the 2^nd statement:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "PublicReadGetObject",
            "Effect": "Allow",
            "Principal": {
                "AWS": "*"
            },
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::yourbucketnamehere/*"
        },
        {
            "Sid": "PublicReadGetObject",
            "Effect": "Deny",
            "Principal": {
                "AWS": "*"
            },
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::yourbucketnamehere/*",
            "Condition":{
                "Bool":
                { "aws:SecureTransport": false }
            }
        }
    ]
}

Don't forget to put your bucket name at yourbucketnamehere.

Now you need to install a SSL certificate. All the information can be found here.
