@AlbertD1 To find the Security Group name associated with a Pega application deployed in AWS Cloud, you can log in to the AWS Management Console, go to the EC2 Dashboard, and then click on Instances. Find the EC2 instance running your Pega application and select it. In the Description tab at the bottom, you will see the Security Groups field, which lists the name(s) of the security groups attached to that instance. Alternatively, if your Pega environment is deployed using an auto-scaling group or behind a load balancer, you can also check the Launch Configuration or Load Balancer settings for associated security groups. These groups control what network traffic is allowed to reach your Pega application.  Please let me know if you need any more info. Thanks
