基于面向对象贝叶斯网络的威胁评估模型
Threat Source Comprehensive Evaluation Model Based on Object-oriented Bayesian Networks
摘要
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.关键词
