In Amazon VPC, there's room for improvement. For example, when we create security groups, I think we should be able to restrict outgoing traffic to secured websites. I know there's a method to restrict that, but we should also be able to design outgoing traffic restrictions at the system level. We should use that to deny ports instead of relying solely on network access controls at the subnet level. Another thing is that I think there should be restrictions within the security group itself, not just for the whole subnet. For instance, when we allow traffic into a specific EC2 instance within a security group, that's only allowing incoming traffic. It doesn't control outgoing traffic. Specific ports should not be allowed to export traffic outside, preventing anyone from getting that traffic. For example, if the port is allowed, it shouldn't allow traffic on port 82 or whatever specific port it is. It needs to control outgoing traffic.
