| If the Desync Mitigation Mode of a load balancer is not 'defensive' or 'strictest', it means that the load balancer is misconfigured. You should see an output similar to this for each load balancer: | ||

| 4. The above script will print out the names of all load balancers that are not using the latest AWS security policy for SSL negotiations. If no such load balancers are found, the script will not output anything. This way, you can easily detect any misconfigurations in your AWS Elastic Load Balancers. | ||

| Remember to replace `'YOUR_ACCESS_KEY'`, `'YOUR_SECRET_KEY'`, and `'YOUR_REGION'` with your actual AWS access key, secret key, and region, respectively. | ||
