物联网环境下不协调目标信息脆弱性风险评估系统

摘要

The traditional risk assessment system has the problems of poor operability and low evaluation accura -cy.Therefore,in the context of internet of things,a risk assessment system of inconsistent target information vul-nerability is designed.According to the rule set,different types of inconsistent target information in the Internet of things are identified,and the problem of the evaluation of the inconsistent target information vulnerability is divided into three levels according to the target,the evaluation criteria and the scheme.The elements of the same level of analysis and comparison, the weight of each factor and various alternative strategies were gotten, considering the risk distribution and inconsistent information distribution,the vulnerability degree of importance to quantitative pro-cessing,fragile vulnerability list of each inconsistent information through evaluation.The risk of inconsistent target information and its losses are analyzed,the corresponding risk size is determined,and the risk grade of inconsistent target information vulnerability is determined.The experimental results show that the designed system is highly op-erational and highly accurate.%传统风险评估系统普遍存在可操作性差,评估准确性低的问题,为此,在物联网环境下,设计了一种不协调目标信息脆弱性风险评估系统.依据规则集识别物联网环境下不同类型的不协调目标信息,将不协调目标信息脆弱性评估问题按照目标、评价准则和方案划分成三个层次.对同一层次中的要素进行分析比较,得到各个要素和各个备选策略的权重,考虑风险分布规律和不协调目标信息分布规律,对脆弱性重要程度施行量化处理,通过评估脆弱性得到每条不协调目标信息的脆弱性列表.对存在风险的不协调目标信息及其造成的损失进行分析,得到相应的风险大小,确定不协调目标信息脆弱性风险等级.实验结果表明,所设计系统可操作性强,评估准确性高.
