Comparative performance analysis of information system security using crisp and fuzzy AHP methods

Today's modern society is very dependent on computer based information systems. This dependence on information systems has lead to a need for securing these systems and this in turn has created a need for knowing how secure they are. In this paper a comparative performance analysis of information system security using crisp and fuzzy Analytic Hierarchy Process (AHP) methods are presented, in which the weight index and the security values are calculated under different security domains in crisp AHP then all the results are compared with the results of fuzzy AHP method. The criteria of information security assessment adopt the international norm ISO/IEC27001, which includes eleven security domains.
