September 11 attacks in the U.S.A., floods of Nari typhoon and malfeasant cases of Financial Information Service Co., Ltd. in Taiwan all indicate that information security has being more important day by day as a result of fast development of information technology, increasing range of users and dependence of an organization on information system. How to evaluate information security of an organization and what valuation criteria should be considered still lack of empirical studies. On the basis of“Integrated System Theory” of information security management, the study applies factor analysis and nominal group technique and collects opinions from experts to construct “Hierarchical Structure of Information Security Valuation Criteria”, which totally includes 9 valuation dimensions and 37 valuation criteria. The result may not only be a reference for the organization to make information security policies but also the foundation to further develop “Information Security Multiple Criteria Valuation Model”. It is obviously a key milestone of empirical studies of information security management.資訊安全整合系統理論資訊安全評估評估準則層級結構Information securityIntegrated system theoryInformation security valuationValuation criteriaHierarchical structure
