Cloud computing has become one of the important technologies for reducing cost and increasing productivity by efficiently using IT resources in companies. The cloud computing system has mainly been built for private enterprise, but public institutions, such as governments and national institutes also have plans to introduce the system in Korea. Various researches have pointed out security problems as a critical factor to impede the vitalization of cloud computing services, but they only focus on the expected security threats and their correspondents for solving problems. Cloud computing security area is classified into managerial, physical and technical area in the research. The research derives the influence of security priorities in each area on the importance of security issues according to the recognition of workers in private enterprise and public institutions by ordered probit model. The ordered probit model is used to analyze the influences and marginal effects of awareness for security importance in each area on the degree of security priority. The results show workers in public agencies regard the technical security as the highest priority, otherwise the physical and managerial security are considered as the critical security factors in private enterprise. This research compared the difference of recognitions for the security priority in three areas between workers in private enterprise which are using cloud computing services and them in public institutions that has never used the services. It contributes to the establishment of strategies in aspect of security by providing guidelines to companies or agencies which want to introduce the cloud computing systems.
