In this paper,the effectiveness assessment indexes system of controls taken in information system which combines with qualitative indexes and quantitative indexes was established properly according to the theory of Information Assurance Technical Framework.Aiming at the common key features of controls taken ininformation system,the evaluation model was built based on fuzzy theory.Finally,the model was used on the effectiveness assessment of controls taken in an information system.The feasibility and validity of the model was proved with the practical case.The method provided effective evidence for the improvement of controls taken in information system.
