AWS Elastic Beanstalk adds controls for default security group management

AWS Elastic Beanstalk now gives customers the option to use default security groups or their own custom security groups when deploying applications. This new feature provides greater control over network access and security configurations. With this update, customers can use custom security groups instead of default security groups for both new and existing Elastic Beanstalk environments. This applies to the EC2 instances within the environment and, for load-balanced environments, to the load balancer as well. Previously, Elastic Beanstalk would automatically add a default security group. This enhancement enables customized security policies and simplifies security management. This feature is available in all of the AWS Commercial Regions and AWS GovCloud (US) Regions that Elastic Beanstalk supports. For a complete list of regions and service offerings, see [AWS Regions](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/). To learn more about using custom security groups with Elastic Beanstalk, see the [AWS Elastic Beanstalk Developer Guide](https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features.managing.ec2.instances.sg.html).
