Information security management as a bridge in cloud systems from private to public organizations

Cloud computing has made it possible for private companies to make rapid changes in their computing environments. However, in the public sector, security issues hinder institutions from adopting cloud computing. To solve these security challenges, in this paper, we propose a methodology for information security management, which quantitatively classifies the importance of information in cloud systems in the public sector. In this study, we adopt a Delphi approach to establish the classification criteria of the proposed methodology in an objective and systematic manner. Further, through a case study of a public corporation, we try to validate the usefulness of the proposed methodology. The results of this study will help public institutions to consider introducing cloud computing and to manage cloud systems effectively and securely.
