基于VC-DRSA的信息系统多属性群决策安全评估

Multi-attribute Group Decision-making Security Assessment Based on VC-DRSA

以某高校校园网络系统作为评估样本,在建立了信息系统安全属性模型的基础上,提出了基于变一致性优势关系粗糙集(VC-DRSA)的多属性群决策的安全评估方法。该方法将VC-DRSA与层次分析法(AHP)相结合,利用VC-DRSA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,对信息系统进行了综合安全评估。实例计算证明,该方法可以有效地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。

Taking the computer networks in a certain university as samples, this paper, with the information system security assessment model as its foundation, proposes multi-attribute group decision-making （MAGDM） security assessment method based on variable consistency dominance-based rough set approach （VC-DRSA）. This assessment method combines VC-DRSA with the analytic hierarchy process （ AHP）, uncovers the inherent information hidden in data via the quality of sorting （ QoS）, 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.
