The analysis of classified protection compliance detection based on Dempster-Shafer theory

Classified protection compliance detection is one of the important methods in information system safety control. In order to solve the uncertainty in compliance detection process, this paper proposes a method of the analysis of classified protection detection based on Dempster-Shafer theory of evidence for rank 4 information system. Firstly, the method establishes a scientific and reasonable index system of classified protection compliance detection for target system. Secondly, combine all the detection items' results of every level in index system with improved Dempster's rule of Combination so that we can obtain the final compliance detection result value with the combination level by level. Finally, verify the feasibility of the method with an example of information system. By using Dempster-Shafer theory of evidence can reduce the uncertainty in compliance detection and resolve the conflict between the various detection results.
