In conclusion, one difference between AWS security groups and NACLs is that SGs operate at the instance level while NACLs operate at the subnet level. Therefore, any rule that allows traffic into an EC2 instance, will automatically allow responses to pass back out to the sender without an explicit rule in the Outbound rule set. Stateless security groups are the traditional kind, and they're easy to understand and manage. C. Use AWS Direct Connect for secure trusted connections between EC2 instances within private subnets.

This makes the design heavy and complex since data needs to be stored. I don't understand how this behavior is regarded as stateful? You can apply multiple security groups to a single EC2 instance or apply a single security group to multiple EC2 instances. A security group has to be explicitly assigned to an instance; it doesn't associate itself to a .
