Fuzzy Modeling for Information Security Management Issues in Cloud Computing

The purpose of this study was to collect key success factors (KSFs) that determine information security management in cloud computing. Through contemporary literature reviews, we emphasized four major aspects: the external dimension, the internal dimension, the technology dimension, and the execution dimension. We used these dimensions to develop a questionnaire for collecting the responses from experts, and then used the fuzzy analytic hierarchy process (Fuzzy AHP) to categorize and analyze these responses. The investigations concluded the six major KFSs: authentication, disclosure prevention, encryption, service model, interface, and customer. Different from previous perceptions, information security management in cloud computing emphasizes factors that are more market-oriented. In addition, we explored several important KSFs, such as service model, interface, and customer criteria. These KSFs differed from the factors commonly regarded in the internet age.
