A risk assessment method of cloud computing based on multi-level fuzzy comprehensive evaluation

The application of cloud computing brings not only enormous economic benefits but also security risks. According to the safety risk problems faced by cloud computing environment, this paper on the basis of the experience of traditional risk analysis methods, qualitatively researches the main factors of cloud computing risk, and adopts multi-level fuzzy evaluation method to analyze multiple decision objectives, which is combined with Analytic Hierarchy Process (AHP) method and fuzzy evaluation theory; Then using this method to construct a model and give an example of calculation in cloud computing, the result of this example shows that the risk assessment method used in this paper is effective, and it has a certain practical application value.
