VPC default security group
The VPC automatically uses the default security group. If you do not specify another security group when launching an instance, each EC2 instance launced in VPC is automatically associated with the security group named “launch-wizard-xx”. For example, the security group name of the first EC2 instance to launch is “launch-wizard-1”.
