A risk assessment model for the operating system of the DTV

The problem of secure operation system risk management is difficult to evaluate quantitatively, a quantitatively risk assessment model for the operating system is proposed in this paper. Through introducing the risk matrix, putting the information safety risk assessment as the risk evaluation model by experts matrix. Borda rule and AHP (Analytic Hierarchy Process) assess the risk assessment process, and achieve the quantitative evaluation of the secure operation system risk management, enhancing the objectivity of the operating system risk quantitative evaluation. In conclusion, the application evaluation model is validated by the examples, and the experimental results show that the model can effectively assess the operating system security risk levels.
