Network security can be provided at gateway-level, in which a security component that augments a firewall employed in a computer network controls the incoming and outgoing network traffic based on applied rule set. The authors propose the concept of switch-port security to limit the traffic on Local Area Networks (LANs). The switch interfaces can be provided with protection using which the traffic on them can be restricted by identifying and limiting the access based on source Ethernet MAC addresses. On assigning MAC addresses to a switch port, it does not forward packets with source addresses outside the group of defined addresses.
