To solve the problem of intelligent capacity of disguise for Honeynet,this paper proposes an intelligent algorithm of dynamic deploying for Honeynet-evolution study.The algorithm based on positive defense can make system take the initiative in face of attack threats and improve its survivability.With the popularization of computer network and the rapid expansion,network security problems become more and more serious,Network security and Countermeasures of the traditional based on firewall and intrusion detection are the defensive nature of the strategy.Honeypot technology is the strategy and means of the initiative and Honeynet is the advanced form of Honeypot.
