use-secure-tls-policy

Default Severity: high

Explanation

You should not use outdated/insecure TLS versions for encryption. You should be using TLS v1.2+.

Possible Impact

Outdated SSL policies increase exposure to known vulnerabilities

Suggested Resolution

Use the most modern TLS/SSL policies available

Insecure Example

The following example will fail the aws-cloudfront-use-secure-tls-policy check. 

 resource "aws_cloudfront_distribution" "bad_example" {
   viewer_certificate {
     cloudfront_default_certificate = true
     minimum_protocol_version = "TLSv1.0"
   }
 }

Secure Example

The following example will pass the aws-cloudfront-use-secure-tls-policy check. 

 resource "aws_cloudfront_distribution" "good_example" {
   viewer_certificate {
     cloudfront_default_certificate = true
     minimum_protocol_version = "TLSv1.2_2021"
   }
 }
