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.
