摘要:
 针对复杂环境下威胁源种类数量繁多、建模难度大以及可维护性差等问题,文中提出一种基于面向对象贝叶斯网络的多威胁源综合评估模型及分类融合方法,并针对该模型的特点提出了单威胁源的层次消元推理算法.各类威胁源采用统一的贝叶斯网络顶层评估类设计,为评估提供了统一的标准接口及框架.融合算法根据同类和不同类威胁源的特点,分别使用S型曲线和考虑可控程度的加权融合.同时,针对单威胁源评估模型中输入输出节点确定的特点,将单威胁源评估模型转换为层次结构,按自底向上的顺序进行消元推理.实验结果表明,该模型能在复杂环境下对多威胁源进行有效的综合评估.
Abstract:
 Aiming at problems of massive threat source type,hard modeling and poor maintainability,a threat source comprehensive evalu-ation model is put forward based on object-oriented Bayesian network,and a level elimination reasoning algorithm of single threat source is proposed according to the characteristics of the model. A unified standard interface and framework is presented by the designing of top class of evaluation. Based on the characteristics of the similar and different threat source,respectively,fuse algorithm uses the S type curve and considers controllable degree of weighted fusion. At the same time,in view of characteristics determined by input and output node in the assessment model of single source threat,which is converted into a hierarchical structure,according to the order of bottom-up for elimination reasoning. Experiment shows that this model can be effective comprehensive evaluation for the multi-threat source in the complex environment.
