| 摘 要： | 在分析已有的安全态势评估和预测方法的基础上,提出了基于信息融合的网络安全态势感知模型.该模型采用D-S证据理论对多源网络安全数据进行融合,计算漏洞、服务、主机、网络的安全态势值.同时根据历史安全态势评估结果,利用支持向量回归理论对未来态势进行预测.相比已有的安全态势评估和预测方法,该模型的结构更加完整,结果更为准确有效.

| Abstract: | Based on analyzing the existing security evaluation and forecast methods,a network security situational awareness model based on information fusion is proposed.Using D-S evidence theory to fuse multi-source network security information,this model gets the security situational values of vulnerabilities,services,hosts and network.It uses support vector regression theory to forecast future security situation in view of historical security situational values.Compared with the existing security evaluation and fo... |
