摘要：Active Worms wreak havoc by exploiting security loopholes and flaws in software design to propagate from one machine to another. Active Worms are different than a traditional virus in that they don�t spread by modifying programs on a single system, but rather by searching for and implanting destructive code onto other systems automatically. In this paper, we propose a novel approach for detecting an intricate type of smart worms called C-Worms. Camouflaging worms (C-Worms) falls under the new category of active worms which conceals its presence by blending with the environment in such a way that it looks analogous to the normal data packet of the network. Thus the propagation of C-Worms and its traffic pattern cannot be determined by the existing worm detection schemes. To countermeasure the C- Worm, we design a new worm detection scheme called Controlled Packet Transmission (CPT) technique where the background traffic is monitored as a function of time. Furthermore, we employ Centralized Worm Detector (CWD) algorithm based on digital signature technique to authenticate each node and monitor the network. Using the CWD algorithm, malicious C-Worm nodes are discarded and the recovered network is monitored. The performance graph obtained experimentally clearly proves that our detection scheme can effectively detect the C-Worm propagation.
