基于模糊数算术运算的信息系统安全性定量评估技术研究

Research on the Technology of Quantitative Security Evaluation Based on Fuzzy Number Arithmetic Operations

对信息系统的安全性进行评估面临大量的不确定性因素 ,主要表现为信息安全的随机性和模糊性。为了处理安全性评估中的主观性和模糊性 ,基于三角形模糊数运算 ,本文提出了一个安全性定量评估的模糊模型 。

There are many uncertain factors in the security evaluation. To deal with this kind of (subjectivity) and fuzziness, a fuzzy model of information system security evaluation is necessary. In (this) paper, a security evaluation approach based on triangular fuzzy number arithmetic operations is (brought) forward, and its rationality and validity is demonstrated by an application example.
