{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": [ 
          "123412341234" 
        ]
      },
      "Action": "s3:Get*",
      "Resource": "arn:aws:s3:::example-bucket/*"
    },
    {
      "Effect": "Deny",
      "Principal": "*",
      "Action": "*",
      "Resource": "arn:aws:s3:::example-bucket/*",
      "Condition": {
        "Bool": {
          "aws:SecureTransport": "false"
        }
      }
    }
  ]
}

An example of a bucket policy that is NON_COMPLIANT with the SSL AWS Config rule is as follows:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": [ 
          "123412341234" 
        ]
      },
      "Action": "s3:Get*",
      "Resource": "arn:aws:s3:::example-bucket/*"
    },
    {
      "Effect": "Deny",
      "Principal": "*",
      "Action": "*",
      "Resource": "arn:aws:s3:::example-bucket/private/*",
      "Condition": {
        "Bool": {
          "aws:SecureTransport": "false"
        }
      }
    }
  ]
}
