Find security group (SG) IDs

Amazon EC2 create and OpenSearch create domain CTs require a security group ID. This will be in the form `sg-02ce123456e7893c7`. Your account has at least two default security groups; see [Security groups](about-security-groups.md). Additionally, you may have security groups that you created for specific purposes. To discover your security groups:
+ AWS Console: Use the EC2 or VPC console to view all security groups for the selected VPC.
+ API/CLI (when logged into your AMS account):

  List your security groups:

  ```
  aws ec2 describe-security-groups
  ```
