Implementation of the fuzzy logic for measuring instrument evaluation results in Information Security Index

Abstract

Information security in an organization is very important and should be a major concern. The government designed and made an application of security standards for the application of information security in Indonesia. This Information Security Index is an application that is used as a tool to analyze and evaluate the level of readiness, completeness and maturity of the application of information security in an organization in accordance with the criteria in SNI ISO / IEC 27001 and COBIT. Fill in the index instrument is expected to be easier and faster in using the application. In its development, there is a method that will be applied to this application, namely fuzzy logic. Fuzzy logic is implemented in the Information Security index application in this case serves to predict the final result. In this study, the prediction results using the Mamdani fuzzy method get the percentage of MAPE error 19.17%, so that the accuracy of the implementation of the Mamdani fuzzy method in the security index application is 80.83%.
