Explanation:
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-network-security.html#default-security-group A
default security group is named default, and it has an ID assigned by AWS. The following are the initial settings
for each default security group:
Allow inbound traffic only from other instances associated with the default security group Allow all outbound
traffic from the instance

instances associated with the default security group to communicate with other instances associated with the
default security group.
