Modeling and Simulation of DDos Attacks Using OPNET Modeler

分析讨论了网络仿真技术在仿真网络攻击方面存在的不足,给出了OPNET平台下可以实现仿真的网络攻击类型。针对所要建立的网络攻击模型对OPNET中所涉及到的关键进程模块进行了深入分析,在此基础上设计并实现了SYNflood网络攻击模型,最后在特定的仿真网络环境中运行了攻击模型,并通过对仿真结果进行分析得到了SYNflood攻击效果与TCP关键参数之间的定量关系,达到了预期的仿真目标。

With OPNET network simulation platform, the limitation of network simulation technique at simulating network attack behavior was analyzed, and a conclusion was drawn that what kinds of network attack could be simulated. The pivotal process module of OPNET and modeled SYN flood attack were analyzed. The attack model was executed against a special target network model, and the quantification relationships were got between SYN flood attack effectiveness and TCP parameters, and expected objective of simulation was achieved.
