Worm is the major hurdle, which restricts the comfortable communication in any networks. Worm is a malicious software program that destroys the normal communication in the networking systems. Every system must not be vulnerable to avoid infection by worm in the computing networks. Defending against such worm still plays vital role to the network programmers. Various countermeasures have been taken so far, still they all fail to establish a fair communication in the networks, for worm has the automatic propagation nature to propagate from one host to the other host. Previous countermeasures provide worm detection at the host level only, which takes more time in worm detection. This paper suggests an alternative approach to detect the worm at the earlier stage, which means detecting the worm at the router level and forwarding wormless packets to the hosts that are connected in the networks. We have studied the comprehensive characteristics of worm and its propagating nature. We define a novel mechanism to detect the worm that propagates in an automatic fashion among the systems in the networks at the router itself and forward the clean and wormless packets. Our mechanism leads to several metrics, which proves our methodology works better than previous countermeasures. Our results show how our mechanism works and how all the metrics are obtained, when worm is being detected at the router itself. Thus, the proposed worm detection scheme obviously leads to the secure communication in the networks.
