【Abstract】 A distributed IP spoof detection system in Intranet is proposed, which can efficiently detect IP spoof behaviors in Intranet. Current techniques of defending IP spoof are analyzed. Aimed at characteristics of Intranet, the design of the system is introduced in detail. The determination method of IP spoof and the design of the monitor, which is a key component of the system, are presented. The implementation of data capture model is also presented. From the experimentation result, it is concluded that the system has the characteristics of high accuracy and real-time performance, but little data traffic. It can be generalized in Intranet of different scales and in other network security systems.更多还原
