EC2 and security groups

In the previous post we setup an EC2 instance and tried to connect it using SSH:

ssh -i ~/Desktop/test-burner-pair.pem ec2-54-237-224-254.compute-1.amazonaws.com
ssh: connect to host ec2-54-237-224-254.compute-1.amazonaws.com port 22: 
Operation timed out

My host has a public address, the subnet has a gateway that allows connection to internet, so ideally it should have worked. However there is additional setting with EC2 - security groups
