<FONT face=Verdana>构建了一个基于贝叶斯网络的信息安全风险概率计算模型,并保证<FONT face=Verdana>其可扩展性、精确性和客观性.模型的网络结构以规划渗透图表现,模型网络参数由专家<FONT face=Verdana>知识确定并利用贝叶斯学习对其进行更新.实例分析表明构建的模型可以正确量化评估信<FONT face=Verdana>息安全风险概率.
<FONT face=Verdana>A planning exploitation graph-bayesian networks model that can be applied <FONT face=Verdana>in measurement of information security risk frequency is proposed
and the <FONT face=Verdana>model’s scalability
accuracy and objectivity are achieved.The model graph <FONT face=Verdana>structure is determined by Planning Exploitation Graph
the local <FONT face=Verdana>conditional probability distributions are computed by combination <FONT face=Verdana>ofexpertise knowledge and the maximum entropy prior probability <FONT face=Verdana>distribution method
and the model parameters are updated with training <FONT face=Verdana>data by Bayesian networks learning.The analysis of the example shows the <FONT face=Verdana>model could evaluate the information security risk frequency <FONT face=Verdana>successfully.
