摘　　要：针对网络安全技术的发展现状,目前大部分网络安全评估方法从本质上来看,都是从安全漏洞的角度进行网络安全评估,然后给出相应的评估结果和解决方案。但主要不足是没有针对网络安全的实际情况对模型的粒度进行深入分析,其模型对网络安全的分析过于理想化。提出了基于粗糙集理论的主机安全评估模型的方法,该方法模型能够利用历史评估记录,把漏洞作为安全要素,在基于粗糙集理论的属性约简能力基础上,建立安全评估模型。Aiming at safe technical development present condition of network, the greatly parts of network safety valuation method comes up to see from the essence currently, carrying on the network safety valuation from of the safe vulnerability, then giving an analyzing result and the solution. Bat the main shortage is the grain degree that didn＇ t aim at the actual circt^tance of the network ea[ety to the model to carry on thorough analysis, its idealizes of model too. Host computer security evaluation model research based on rough set theory was put forward. This model considered the vulnerability as a security factor and the security evaluation model was built from historical evaluation records by using attribute reduction.
