An outdated SSL policy is in use by a load balancer.
Default Severity: critical
Explanation
You should not use outdated/insecure TLS versions for encryption. You should be using TLS v1.2+.
Possible Impact
The SSL policy is outdated and has known vulnerabilities
Suggested Resolution
Use a more recent TLS/SSL policy for the load balancer
Insecure Example
The following example will fail the aws-elb-use-secure-tls-policy check.
resource "aws_alb_listener" "bad_example" {
ssl_policy = "ELBSecurityPolicy-TLS-1-1-2017-01"
protocol = "HTTPS"
}
Secure Example
The following example will pass the aws-elb-use-secure-tls-policy check.
resource "aws_alb_listener" "good_example" {
ssl_policy = "ELBSecurityPolicy-TLS-1-2-2017-01"
protocol = "HTTPS"
}
