Pattern: An outdated SSL policy is in use by a load balancer
Issue: -
You should not use outdated/insecure TLS versions for encryption. You should be using TLS v1.2+.
Resolution: Use a more recent TLS/SSL policy for the load balancer.
Example of incorrect code:
resource "aws_alb_listener" "bad_example" {
ssl_policy = "ELBSecurityPolicy-TLS-1-1-2017-01"
protocol = "HTTPS"
}Example of correct code:
resource "aws_alb_listener" "good_example" {
ssl_policy = "ELBSecurityPolicy-TLS-1-2-2017-01"
protocol = "HTTPS"
}
