摘要
为了获取信息系统安全状况并制定相应的安全解决方案,提出了基于变精度粗糙集(VPRS)的多属性群决策安全评估方法.以某高校校园网络系统作为评估样本,在信息系统安全评估模型的基础上,将VPRS与层次分析法(AHP)相结合,利用VPRS分类质量的概念,挖掘出隐含在数据背后的内在规律.在确定安全属性权重的基础上,对信息系统进行综合安全评估.实例证明,该方法可以有效解决多属性群决策的瓶颈问题,在信息系统安全评估中具有实际意义.
In order to understand the security conditions of ing solution of security problems, this paper proposed mu security assessment method based on variable precision rou ormation system and acquire the correspond- attribute group decision-making （MAGDM） set （VPRS）. Taking the computer networks in a certain university as samples, this assessment method, with the information system security assessment model as its foundation, combines VPRS with the analytic hierarchy process （AHP）, uncovers the inherent information hidden in data via the quality of classification, and makes a synthetic security assessment of the information system after determining the security attribute weight. The sample findings show that this method can effectively remove the bottleneck of MAGDM, thus assuming practical significance in information system security assessment.
