摘　　要：针对局域网终端用户普遍存在很少使用防火墙的现象,结合防火墙的工作原理和DOSnuke攻击的特点,在OPNET网络仿真环境中设计DOS nuke攻击的攻防模型并在仿真环境中模拟DOS nuke攻击,通过加入防火墙之后受害主机接收到的网络数据包流量剧烈减少的实验结果,验证防火墙在防御DOS nuke攻击方面具有很好的功能.该方法对于仿真环境下分析防火墙的各项安全功能具有重要的意义.With the phenomenon that users of LAN seldom use firewall in general, the model of DOS nuke attack and defense is designed in OPNET simulation environment by combinating with the principle of firewall and the character of the DOS nuke attack. The DOS nuke attack is also simulated in the environment. On the base of these, the security function of firewall on defensing DOS nuke attack is proved by the result that the network packet volume of victim host computer is dramatically reduced after adding a firewall. It has important reference value of proving defense ability of firewall in simulation environment.
