With the accelerate development of information, enterprises are becoming increasingly dependent on information systems, therefore, ensuring information security becomes the core work of enterprises information management.

After analyzing the four aspects based on the fuzzy set theory, then constructs the membership matrix of

The weights of the risk factors are calculated with the entropy theory to reduce the subjectivity bias, integrating the comprehensive risk results to output the risk rating. An example application proves that the method is a feasible and effective method of assessment, the results will have a certain theoretical significance and practical value.
