Risk Assessment Model of Information Security for Transportation Industry System Based on Risk Matrix

Risk assessment is a vital part of classification protection system for transportation industry system information security. In this paper, an information security risk assessment model based on risk matrix was put forward for heterogeneous-based transportation industry system. The risk matrix method was brought into assessment system. Then an accurate risk assessment model was constructed. In this model, there were three critical modules, such as expert 2-dimension matrix, Borda sequence and gray analytical hierarchy process. In this assessment system, qualitative analysis was firstly processed. Those three modules have quantitative feature, so the assessment results described by words before can be denoted by numbers. The final quantitative results were obtained by related equations. This model was put into practical application of transportation security decision support system for emergency response, and the application results indicate that this model can increase the objectivity of the assessment.
