Abstract:The targets of net attacks could be summed up to data resources, computational resources and connection resources. To resist net attack, which focuses on data resource, an intrusion-deception-based dynamic network defensive system was present in this paper. and redirection technology in the Intrusion Deception System were also discussed, The problems of redirection technology were analyzed and a seamless redirection solution was described, including the technology of redirection base on Socket and Environment States synchronization. The initiative and security of the Intrusion Deception System were assured
