Network Worm Propagation Model and Early Warning Studies

With the network system application and the increased complexity.The network worm spreads rapidly and become an important network security threat. In the network environment,. the diversification route of transmission and complex application environment made the frequency of network worms increased latent strongly, broader coverage, the network worms malicious code research became, the primary topic. Papers about network worm first comprehensive overview of the research and then analyze the basic definition of network worms, functional structure and working principle, and then study the campus network environment worm propagation model, the network worm spreads through the principle and mode of behavior analysis, a Based on client of the network worm early warning methods. The network worm with existing early warning methods, the new methods are more effective, but also warning unknown worms. And, because this method combines client and server-side function, the burden on the server side reduced so greatly.
