Active worms spread in an antomated fashion and can flood the Internet in a very short time. Modeling the spread of active worms can help us understand how to monitor and defend against the propagation of active worms effectively. In this paper, we present an active worm propagation model with discrete time, referred to as Discrete Time Worm Propagation (DTWP), which considers the propagation of anti-worms. The figure of simulation by matlab indicates that compared with the AAWP model, our DTWP model can characterize the latter propagation of active worms more effectively.

With the wide application of the Internet, worm's threat to security of computer system and security of network increases day by day. Especially under the environment of Internet, the diversified spread ways and the complicated applied environment make the emergence frequency of the network worm increase, the propagation becomes faster, and the coverage rate is wider. In this paper, the definition and research situation of Internet worms, exploration function component and execution mechanism are first presented, then the scanning strategies and propagation model are focus discussed, and finally discuss the development trend of propagation and the future research directions of Internet worm.
