Abstract: The simulation of network terminals of existing network attack and defense system is realized mostly through accessing real devices, utilizing virtual machines and simple protocol realizing. These methods are either costing too much and inflexible or too low in simulation level and incapable to respond to application layer requests. Aiming at these problems, this paper puts forward the method of combing network attack and defense simulation system with virtual honeypot which acts as the virtual network terminal. The paper also presents a practical technical solution for using virtual honeypot to realize network attack and defense system terminal subsystem.

Key words: network security, honeypot, network simulation, network attack and defense
