API Gateway domain name uses outdated SSL/TLS protocols.

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You should not use outdated/insecure TLS versions for encryption.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Outdated SSL policies increase exposure to known vulnerabilities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-api-gateway-use-secure-tls-policy check.

resource "aws_api_gateway_domain_name" "bad_example" {
	security_policy = "TLS_1_0"
}

Secure Example

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

resource "aws_api_gateway_domain_name" "good_example" {
	security_policy = "TLS_1_2"
}
