Abstract: To study and develop the confrontation capability of computer network is necessary to gain information superiority and network domination.Network confrontation training simulation system helps cultivate confrontation persons with ability and increase confrontation standards.This paper presents a network confrontation training simulation system,and discusses the related subsystems including interactive confrontation training simulation system,support software system,evaluation system,and information data base.The system can provide a favorable environment for confrontation theory research and confrontation training.It is of great significance and benefits in practice.
