Research on information engineering surveillance risk evaluation based on fault tree analysis

Information security risk analysis method is now a hot issue of information security management field. Fault tree analysis method has proposed since the 1960s, obtain the widespread application in many large-scale complicated system´s security fall-safe analyses. It´s recognized as an effective method for the complex system reliability, security analysis. The basic principle, qualitative analysis and quantitative analysis of fault tree analysis method are introduced. And this article introduced briefly the information security risk analysis method, and to has carried on the exhaustive elaboration based on fault tree´s risk analysis´s modeling way and the analysis principle. Finally, an example is introduced to tome to the conclusion whether the project is feasible.
