摘　　要：随着网络和信息技术的高速发展,赛博空间成为各国战略争夺的新战场。为了更好地了解和研究赛博空间作战这种新的战争形式,可以利用仿真技术作为研究和试验赛博空间的手段。随着仿真技术的发展进步,仿真已经开始运用在网络安全的研究上,使得能够较为容易地模拟各种条件下的网络环境,以探索战术和技术的必要条件。赛博空间网络防御仿真利用OPNET作为仿真建模工具,采用模块化、可重用的建模方式模拟赛博网络防御等行为,搭建典型的DDos网络攻防场景,通过仿真结果一方面评估DDos攻击对系统的危害,另一方面测试拟采取的网络防御手段可以达到的效果。Along with the rapid development of network and information technology,cyberspace becomes a new field of strategic contention for various countries.In order to better understand and study the new forms of war in cyberspace operations,simulation techniques may be used as a means to study and test cyberspace.With the development of technology,simulation has begun to be applied to the research of network security,thus making it easier to model the network environment under various conditions and explore the necessary conditions for tactics and technology.Cyberspace-network defense simulation,with OPNET as the simulation modeling tool and modularized and reusable modeling method,simulates the cyberspace defense and other behaviors,and builds up the typical DDos network attack and defense scene.Based on the simulation results,the harm of DDos attack to the system is evaluated and the effect of to-be-taken network defense means tested.
