resource "aws_load_balancer_backend_server_policy" "negative6" {
load_balancer_name = aws_elb.wu-tang.name
instance_port = 443
policy_names = [
aws_load_balancer_policy.wu-tang-root-ca-backend-auth-policy.policy_name,
resource "aws_load_balancer_backend_server_policy" "negative6" {

Explanation in Terraform Registry
Attaches a load balancer policy to an ELB backend server.
Tips: Best Practices for The Other AWS Elastic Load Balancing Resources
In addition to the aws_elb, AWS Elastic Load Balancing has the other resources that should be configured for security reasons. Please check some examples of those resources and precautions.
aws_elb
Ensure your ALB blocks unwanted access
It is better to limit accessibility to the minimum that is required for the application to work.
