Recently, as evaluation of information security (IS) management become more diverse and complicated, the contents and procedure of the evidence to prepare for actual assessment are rapidly increasing. As a result, the actual assessment is a burden for both evaluation agencies and institutions receiving assessments. However, most of them reflect the evaluation system used by foreign government agencies, standard organizations, and commercial companies. It is necessary to consider the evaluation system suitable for the domestic environment instead of reflecting the overseas evaluation system as it is. The purpose of this study is as follows. First, we will present the problems of the existing information security assessment system and the improvement direction of the information security assessment system through analysis of existing information security assessment system. Second, it analyzes the technical guidance for information security testing and assessment and the evaluation of information security management in the Special Publication 800-115 'Technical Guide to Information Security Testing and Assessment' of the National Institute of Standards and Technology (NIST). Third, we will build a framework to implement the evidence collection system and present a system implementation method for the '6. Information System Security' of 'information security management actual condition evaluation index'. The implications of the framework development through this study are as follows. It can be expected that the security status of the enterprises will be improved by constructing the evidence collection system that can collect the collected evidence from the existing situation assessment. In addition, it is possible to systematically assess the actual status of information security through the establishment of the evidence collection system and to improve the efficiency of the evaluation. Therefore, the management system for evaluating the actual situation can reduce the work burden and improve the efficiency of evaluation.

As new Information technology such as IoT develops rapidly, a lot of changes are occurred in our lives. The Internet of Things is the network of physical objects or things embedded with electronics, software, sensors and connectivity to enable it to achieve greater value and service by exchanging data with the manufacturer, operator and/or other connected devices. This change is also applied to tourism industry. These days many people make a tour reservation using the internet. But it is required to consider the efficiency and security of tour reservation system. In this paper, we suggest a tour reservation system. First, we describe the computer reservation system, hotel reservation system and reservation system. Second, we perform the modeling of general reservation system and suggested reservation system. Third, performance evaluation is carried out with respect to efficiency and security. The results show that the suggested reservation system has a better performance than a general reservation system. At last we described the results and future works.

Cloud computing provided as a service type by sharing IT resources cannot be activated unless the issue of information security is solved. The enterprise attempts to maximize the efficiency of information and communication resources by introducing cloud computing services. In comparison to the United States and Japan, however, cloud computing service in korea has not been activated because of a lack of confidence in the security. This paper suggests core evaluation criteria and added evaluation criteria which is removed the redundancy of the security controls from existing ISMS for Korean cloud computing through a comparative analysis between domestic and foreign security controls of cloud certification scheme and guidelines and information security management system. A cloud service provider certified ISMS can minimize redundant and unnecessary certification assessment work by considering added evaluation criteria.

As Korea's industrial competitiveness and technological prowess increase, collaboration and technical exchanges with contracting companies are increasing. In an environment where cooperation with the contracting company is unavoidable ordering companies are also striving to prevent leakage of technologies through various security systems, policy-making and security checks. However, although the contracting companies were assessed to have a high level of security management the leakage of technical datas are steadily increasing. Issues are being raised about the effectiveness of the security management assessment and the actual security management levels. Therefore, this study suggested a security management system model to improve security management efficiency in the general contract structure. To prove this, analyze the efficiency of 36 contractor companies for the technical datas security management system using the DEA model. The results of the analysis are reflected in the assessment results. Lastly, suggestions for improving the effectiveness of the technical datas security system are proposed.
