摘要
网络安全威胁评估是对网络威胁响应和预警的前提和基础,提出采用变精度粗糙集理论进行威胁评估的方法。该方法利用安全要素和威胁等级建立决策表,通过对决策表约简,获取决策规则,计算整个网络的安全等级。仿真实验表明,采用该方法的评估结果更加准确、直观。
Network security threats assessment is the premise and foundation for Network threats Response and warning.A threats assessment method based on variable precision rough set Theory is presented.This algorithm construct.This method establish a decision table with security elements and threat grades,acquire the decision rule by relative reduction,and finally calculate the security grade.Experiment results demonstrate that it is more shows that evaluation results by our method are more accurate and intuitive than others.
