I am deploying a service on Elastic Beanstalk (EB). When you create an EB environment, it asks you to select a security group for hosts running the application. No matter what you select, EB will always use your selected security group in addition to a generated security group which allows all external HTTP and HTTPS traffic on ports 80 and 443. Is there any way to disable this? I would like the allowed traffic to be determined by my selected security group. I do not want to allow any external traffic.
