A Security Situation Assessment Model of Information System for Smart Mobile Devices

The accuracy of the existing security situation assessment model of information system for smart mobile devices is affected by expert evaluation preferences. This paper proposes an information system security situation assessment model for smart mobile devices, which is based on the modified interval matrix-entropy weight-based cloud (MIMEC). According to the security situation assessment index system, the interval judgment matrix reflecting the relative importance of different indexes is modified to improve the objectivity of the index 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 evaluation experiment on the departure control system for smart mobile devices not only verify the validity of this model but also demonstrate that this model has higher stability and reliability than other models.
