Abstract: Facing more and more serious Internet security problems and the shortage of network security professionals, the problem of how to cultivate professionals rapidly must be urgently resolved. Cyberspace security confrontation simulation is a method that can cultivate security professionals efficiently and improve the ability of security technology. Currently, network security competitions mainly consist of four models, namely pointtopoint confrontation, oneway attack, public positional interattack and private positional interattack, whose notion and boundaries between each other, however, are ambiguous and confusing. This paper classified these models according to characteristics of the athletes and the target network. They can be classified as single role and dual role model, based on the athletes character; the single level and multilevel model, based on the target network. A dual role of multilevel network confrontation simulation model is proposed and constructed. A cyberspace security confrontation simulation system based on cloud computing and virtualization is designed. This system has been stably used in the Information Security and Countermeasures Contest in 2015, whose deployment efficiency and system stability has been tested with results showing that this system was highly reliable and suitable.
