The current technology drain at small and medium-sized enterprises in Korea is very serious. According to the National Intelligence Service's survey data, 69 percent of technology leaks are made through employees of small and medium-sized enterprises. A document security system was introduced to compensate for the problem. However, small and medium-sized enterprises are not doing well due to their poor environment. Therefore, it proposes a document security system suitable for small businesses by developing a location information machine learning system that automatically creates a document security Green Zone through learning, and an ECM-based electronic document leakage prevention system that manages generated Green Zone information by reflecting it into the document authority system. And step by step, propose a universal solution through cloud services..

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.

The importance of information security is increasing, and various efforts are being made to improve users' information security behaviors. Among these various efforts, information security education is mainly aimed at providing users with information security knowledge and improving information security awareness. This study classified the types of information security education into offline and online to examine the effects of each education method on attitudes toward information security (perceived severity, vulnerability, self-efficacy and response-efficacy) and information security behaviors. A survey was conducted for users with information security education experiences. The results obtained by comparing the differences in the path coefficients of personal information security behaviors according to information security education experiences showed that security behaviors were more significant in the online experience group than the offline group. In addition, gender differences were analyzed, and it was found that females had a greater impact on information security attitudes than males. This study also found that among Internet users with online information security education experience, females tend to have more information security behavior than males, but there were contrasting results among users with offline information security education experiences. The results of this study finally address the necessity of reflecting users' personalities in the systematic design of information security education in the future. Furthermore, the results of this study support the need for an appropriate education system that sufficiently understands education types to maximize the effects of information security education.

Growing information threats have threatened organization to lose information security controls in these days. Many organizations have accepted the various information security management systems does mention necessity of a continuous evaluation process for the executions of information security management in a theoretical aspect. This study suggests a continuous evaluation process for information security management reflecting the real execution of managers and employees in organizations.

Coordination has been identified as a concern in the cross-cutting issues of food security and nutrition (FSN) in Cambodia. Food Security and Nutrition Information System (FSNIS) in Cambodia is the only "entry portal" to support policy formulation and decision-making with regard to FSN. While this knowledge and information management system has earned a respectful reputation, Council for Agricultural and Rural Development (CARD) faces many challenges in the implementation of the system. This paper will present how FSNIS has been developed and impacts on policy or strategy related to FSN. In addition, sustainability of the system is a key challenge for FSNIS; yet it is interesting to see how it works. Along with a success story, FSNIS is recognized by its stakeholders as the most successful knowledge and information management system in the field of FSN in Cambodia.

As various IT and OT systems such as Electronic Chart Display and Information System and Automatic Identification System are used for ships, security elements that take into account even the ship's construction and navigation environment are required. However, cyber security research on the ship and shipbuilding ICT equipment industries is still lacking, and there is a lack of systematic methodologies through threat modeling. In this paper, the Data Flow Diagram was established in consideration of stakeholders approaching the ship system. Based on the Attack Library, which collects the security vulnerabilities and cases of ship systems, STRIDE methodologies and threat modeling using the Attack Tree are designed to identify possible threats from ships and to present ship cyber security measures.

Smart grid is a next-generation intelligent power grid that applying ICT to power grid to maximize the energy efficiency ratio. Recently, technologies and standards for smart grid are being developed around the world. Information security which is an essential part of smart grid development has to be managed continuously. Information security management system certification for organizational risk management has been implemented in Korea. Although preparation for information security management system certification which is applicable to smart grid is considered, there are no specific methods. This paper is to propose core and added evaluation criteria for Korean smart grid based on K-ISMS through comparative analysis between ISMS operated in Korea and smart grid information security management system developed in the United States. Added evaluation criteria enable smart grid related business that certified existing ISMS to minimize redundant and unnecessary certification assessment work.

We consider an information system where its throughput deteriorates due to security threats and evaluate information security investment portfolios. We assume that organizations adopt information security countermeasures (or portfolios consisted of countermeasures) to lessen the damage resulted from the productivity (or throughput) deterioration. A probability model is used to derive the system throughput and the average number of repairs according to the occurrence rate of security threats. Considering the revenue from throughput, the repair cost, and the investment for the security system, the net present value for each portfolio is derived. Organizations can compare information security investment portfolios and select the optimal portfolio.
