Research on control strategy of worms spread in complex networks

With the explosive growth of network applications and complexity, the threat of Internet worms against network security becomes increasingly serious. In this paper, s the structure and characteristic of complex networks are first analyzed, then the exploration function component and execution mechanism of Internet worms are presented, the strategies for worm scans are analyzed and evaluated, some critical techniques of internet worm prevention are given, meanwhile the advantage and disadvantage of these methods are analyzed, finally find how to improve the capability of worm detection system.
