Application of Comprehensive Fuzzy Evaluation in LAN Security

Local area network (LAN) security evaluation has not only become more important but also affected the LAN or internet advancement and development. Above all, the LAN security characteristics of are analyzed. On the basis, the quality evaluation system framework of LAN security indicator is established. Fuzzy evaluation index system is established to consider various influential factors. As to indexes system, comprehensive fuzzy evaluation (CFE) model and methods are setup and used to check for practical example. Using CFE model and case study, it is concluded that, based on LAN security evaluation indexes system, CFE method is used to evaluate and solve the unclear boundary of some LAN security indicators and inaccurate fuzziness, which is proved to be practicable.
