If you don't specify a different security group when you launch the instance, we associate the default security group with your instance. You have to open the security group to the IPs and ports provided by the vendor service. You can use the default security group and still customize it according to your liking (although we don’t recommend this practice because groups should be named according to their purpose.) In allowing traffic to reach an instance, Amazon EC2 evaluates all of the rules from all of the security groups associated. Then you'll want to mark your calendar.
