What is a Security Group?
Virtual private cloud Security Groups control inbound and outbound traffic at the instance level, much as Access Control Lists (ACLs) control traffic at the subnet level. Each instance may be assigned up to 5 security groups, and each instance in a subnet could be assigned to a different set of security groups.
Each security group follows one set of rules for inbound traffic and a separate set for outbound traffic. The default security group allows all outbound traffic and inbound traffic from instances assigned to the same security group only. In other words, if you want to restrict outbound traffic, or if you want to allow inbound traffic from network interfaces outside your security group, you will need to change the rules.
Security rules are a useful way to establish consistent traffic flow rules for similar instances across different subnets.
