基于AHP的水下油气生产控制系统信息安全评估

Information security evaluation of subsea oil and gas production control system based on AHP

为解决水下油气生产控制系统的信息安全风险评估问题,提出基于层次分析法的水下控制系统信息安全评估方法。首先依据相关评估准则和规范标准,构建了水下控制系统信息安全风险评估层次模型,并通过层次分析法得到各层级评价指标的权重系数;行业专家对各项指标评分后,再使用加权平均法得到综合评价分值及其对应的风险等级。实例分析结果表明,层次分析方法可合理有效地量化控制系统信息安全风险,解决了风险评估过度依赖专家经验和不确定性问题,提高了评估结果的准确性和科学性。

In order to solve the problem of information security risk assessment of underwater control system,this paper proposes an information security assessment method of underwater control system based on analytic hierarchy process.Firstly,according to the relevant evaluation criteria and standards,the hierarchical model of information security risk evaluation of underwater control system is constructed,and the weight coefficients of evaluation indexes at each level are obtained by analytic hierarchy process;After the industry experts score each index,the weighted average method is used to1 obtain the comprehensive evaluation score and its corresponding risk grade.The results of the case analysis show that the analytic hierarchy process can reasonably and effectively quantify the information security risk of the control system,solve the problem of over reliance on expert experience and uncertainty in risk assessment,and improve the accuracy and scientificity of the assessment results.
