The outbreak of worm is very frequent today. It has great impact on the society infrastructure and people's wealth security. A large number of experts have devoted themselves to the research of worm propagation modeling. Both deterministic model and stochastic model have been used in modeling worm spread. In this paper, we analyze the worm functional structure, and then propose a deterministic worm model based on two-factor worm mode, named FWM model, by considering the impact of firewall on the worm propagation. The worm propagation model we proposed is more flexible than two-factor model. It can reflect the change of worm propagation dynamically. In addition, based on the simple worm model, we analyze the firewall penetration technology on the worm propagation. The result of simulation shows that the use of firewall blocks the worm's spread speed.
