DDoS主动防御系统防御能力量化仿真研究

Study on Quantitative Simulation of DDoS Active Defense System's Defense Capability

针对防御能力量化模型不符合DDoS主动防御系统特点的问题,分析了影响DDoS主动防御系统防御能力的防御设备指标,从防御收益和防御成本两方面建立DDoS主动防御系统防御能力量化模型。在OMNeT++中,设置不同的防御设备指标进行仿真实验,探索总结了DDoS主动防御系统设备指标与系统主动防御能力的关系,为提高DDoS主动防御能力提供了参考。

To solve the problem that defense capabilities quantification model does not fit the characteristics of DDoS active defense system,the paper analyzes index of defense equipments. And the paper establishes DDoS active defense model from two aspects： defense profit and defense cost.Then the paper does many simulation experiments with different indexes in OMNeT ＋ ＋. The experiments explore the relationship between equipment index and system＇s defense capability,providing reference for improving the DDoS active defense system.
