摘要
网络安全是近年来国内的重点研究领域,没有网络安全就没有国家安全.针对网络安全中数据源多样性、复杂性等特点,提出了一种基于支持向量机及自适应权重的网络安全态势评估模型.该模型由训练和预测模块组成,训练模块采用先验知识方法获取网络安全关注的重点数据,结合支持向量机和权重策略寻求评估模型.预测模块进行实时网络安全态势评估.通过实验过程和结果分析,表明该模型较好的支持小型网络安全态势的实时预测评估.
Network security has become a priority research field in China in recent years,for there would be no national security without network security.In consideration of the characteristics of data source in network security like diversity and complexity,this study proposes an evaluation model of network security situation based on Support Vector Machine（SVM）and self-adaptive weight.The model is composed of training module and prediction module.The training module is used to obtain the key data concerned by network security through prior knowledge method and build evaluation model with a combination of SVM and weight strategy.The prediction module is used for real-time network security situation evaluation.Analysis of experimental process and results indicates that the proposed model can favorably support the realtime prediction and evaluation of the security situation of small-size networks.
