Abstract
The accuracy of existing information system security situation assessment methods is affected by expert evaluation preferences. This paper proposes an Information System Security Situation Assessment Model (ISSSAM), which is based on the Modified Interval Matrix-Entropy Weight based Cloud (MIMEC). Based on the system security situation assessment index system, the interval number judgment matrix reflecting the relative importance of different indicators is modified to improve the objectivity of the indicator layer weight vector. Then, the entropy weight based cloud is used to quantify the criterion layer and the target layer security situation index, and the security level of the system is graded. The feasibility and effectiveness of this model are verified by the security situation assessment of the Departure Control System (DCS). Through the comparison and analysis of the evaluation results based on entropy weight coefficient method and traditional AHP method, it is shown that the model we proposed has good stability and reliability.
