一种基于相关度矩阵的安全度量模型

定性或定量的安全评估技术是保障系统安全重要手段.量化的安全度量技术在挖掘数据潜在的安全关系和处理大数据量方面比定性方法有明显优势.如何系统地将安全因素进行量化表达,构造可信度高的量化评估模型是量化技术的难点.把安全因素划分成动态、静态两类因素集合,采用概率的方式量化因素对系统安全状态的影响,有效地解决了量化表达的问题,并据此给出了一个基于相关度矩阵的条件概率模型.经仿真结果验证,模型评估出的结果能够较好地反映系统安全状态的变化情况.

A Security Metric Model Based on Relation Matrix

How to qualify and quantify the measurement of security is a critical means to guarantee the smooth execution of the system.The quantification of the security shows obvious superiority over the qualitative ways,especially when it is used to process large datasets and mine the security relations.This paper divides the security factors into static and dynamic categories.The probability method has been used to measure the impact of the system security factors.This relation matrix based probability model succes...
