This tutorial will guide you on how you can create your own security group in AWS console. Amazon EC2 Security Groups acts as a virtual firewall that controls the traffic for one or more instances. When you launch an instance, you associate one or more security groups with the instance. You add rules to each security group that allow traffic to or from its associated instances.

For example, if you are going to launch a web server instance, you would probably setup a security group which allow of HTTP or HTTPS protocol.
