Do you get charged for a security group in AWS EC2

Question

I recently had an EC2 instance that I terminated, I've deleted everything except for the Default Security Group which I am not allowed to delete. Note: I've deleted all the Inbound Rules and Outbound Rules. My bill still reflects EC2 charges which are by the hour. Do I need to worry about deleting this security group?

Answer 1

There is no charge applicable to Security Groups in Amazon EC2 / Amazon VPC.

You can drill-down into your billing charges via the Billing Dashboard. Just click Bill Details, expand the Elastic Compute Cloud section and a breakdown of charges will be displayed. You can get a better understanding of the EC2/VPC concepts from the AWS Certification.
