정보보안 예산 수립에서 퍼지 AHP의 적용을 통한 위험 비용 분석
Cost Risk Analysis for Preparing Budgets of Information Security using Fuzzy AHP
Abstract
First, we introduce brief fuzzy set theory and fuzzy AHP (Analytic Hierarchy Process) methodology. Then,the cost elements that comprise yearly budget are presented and the priorities among the cost elements arecalculated by fuzzy AHP. The cost elements that are exposed to risk are evaluated from the both perspectivesof the risk impact and risk occurrence possibility which are expressed as linguistic terms. To get informationon the risk profiles—pessimistic, most likely, and optimistic—for each cost element, the evaluation isaccomplished and the result is presented. At last, the budget ranges—minimum, mode, maximum—for eachcost element are estimated with the consideration of the risk profiles.
