title: AWS API Gateway should prevent use of TLS v1
body: <p>Refering to <a href="http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/secure-connections-supported-viewer-protocols-ciphers.html" rel="noreferrer">AWS Cloudfront Documentation</a>, AWS API Gateway supports TLS v1.0, v1.1, v1.2.</p>
  
  <p>But I want to limit the encryption protocols to TLS v1.1 and v1.2 for my Gateway API. Where do I configure this?
  I do not see any cloudfront distribution for my API. Gateway resource page does not have an option to specify the security protocol.</p>
  
  <p>My API is running in production for last 2 years using a custom domain.
  Any idea how do I limit my API to TLS V1.1 and V1.2 protocols only in API Gateway?</p>
