摘要
目的:以安全态势评估概念和预测方法为基础,提出以信息融合为核心的网络安全态势感知模型。方法:首先对网络安全态势感知研究现状展开研究,然后给出相应的感知模型。在此模型中,对多源网络安全信息进行综合考量,并借助于D-S证据理念,得到相应的评估结果,而所涉评估对象包括主机、网络、漏洞和服务等。借助于支持向量回归理论,得到网络安全态势值。结果:本次研究所提出的感知模型,其诸多功能基本实现。结论:与已有的预测和评估法进行对比,以信息融合为核心构建的网络安全态势评估预测模型的结构完整度和预测准确性都具有显著优势。
Purpose: Based on the concept and prediction method of security situation assessment, a network security situation perception model based on information fusion was proposed. Method: Firstly, the current situation of the re. search on network security situation perception was analyzed, and then the corresponding perception model was sug. gested. In this model, the multi-source network security information was considered comprehensively, and the corre. sponding evaluation results were obtained with the help of D-S evidence concept. The target of evaluation includes host, network, vulnerability and service. With the support vector regression theory, the network security situation val. ue is obtained. Results: Many functions of the perception model proposed by this research are basically realized. Con. clusion: Compared with the existing prediction and evaluation methods, the structural integrity and prediction accura. cy of the network security situation assessment prediction model based on information fusion have significant advan. tages.
