Research on the evaluation of information security management under intuitionisitc fuzzy environment

Abstract

With the rapid development of computer technology and information technology, information has been a new asset of the enterprise and played more and more important role. How to protect information security is the problem that all companies need to solve together. In this paper, we propose a novel method to evaluate the enterprise's information security management under intuitionisitc fuzzy environment. The intuitionistic fuzzy set which considers not only membership and non-membership, but also hesitancy can express the decision maker's preferences more precise. The extended TOPSIS approach with correlation coefficient instead of distance measure is introduced in the procedure of decision making. Finally, the application and comparison analysis are demonstrated to verify validity and reliability of the method.
