Security groups in a VPC mention which traffic is allowed to or from an Amazon EC2 instance. Network ACLs operate at the subnet level and evaluate the traffic that is entering and exiting a subnet. Network ACLs can be used to set both Allow as well as Deny rules. Network ACLs do not filter traffic between the instances in the same subnet. Besides this, the network ACLs performs stateless filtering while security groups perform filtering.
