Based on the Construal Level Theory, this study aims to investigate how information security vaccine users' selection intentions differ from each other according to the selection time of information security vaccine, advertisement message types, and information security knowledge levels. For the foregoing, this study conducted an experiment by applying an experimental design of 2(knowledge level: high/low) ${\times}2$(temporal distances: short distance/long distance) ${\times}2$(advertisement message types: how(concrete)/why(abstract)) on computer security vaccine softwares. As a result, this study confirmed that the selection intentions about information security vaccines differed from each other according to the temporal distance and advertisement message type, and also varied according to the information security knowledge level. In conclusion, this study provides an implication that the consideration of well-timed persuasive message is especially important for the users at the high level of knowledge. Also, this research implies the necessity of development of abstract thinking ability based on temporal distance for the users at the low level of knowledge.

Recently, organizations are demanding strict information security behavior from their employees. Strict information security policies and techniques can cause information security related stress. The purpose of this study is to present the negative effects of information security related techno stress and role stress that reduce knowledge sharing behavior and person-organization fit. The survey was conducted to people working in organizations with information security policies and system, and the research hypothesis was verified by structural equation modeling using 309 samples. As a result of the study, person-organization fit had a positive effect on knowledge sharing behavior, but role stress had a negative effect. And, techno-stress negatively affected the person-organization fit. Additionally, role ambiguity had a moderating effect between person-organization fit and knowledge sharing behavior. The implications of the study were to confirm the negative effects of information security related techno stress and role stress, and to suggest directions for minimizing negative behavior of insiders.

Organizations depend on smart working environments, such as mobile networks. This development motivates companies to focus on information security. Information leakage negatively affects companies. To address this issue, management and information security researchers focus on compliance of employees with information security policies. Countermeasures in information security are known antecedents of intention to comply information security policies. Despite the importance of this topic, research on the antecedents of information security countermeasures is scarce. The present study proposes information security intelligence as an antecedent of information security countermeasures. Information security intelligence adapted the concept of safety intelligence provided by Kirwan (2008). Information security intelligence consists of problem solving skills, social skills, and information security knowledge related to information security. Results show that problem solving skills and information security knowledge have positive effects on the awareness of employees of information security countermeasures.

Knowledge management system building knowledge acquisition, knowledge share, and knowledge maintenance for the member of corporation is expanded throughout whole industry to cope with rapid business environment. Electronic document basing knowledge management system can copy, print, and transfer knowledge to another party, so it is being regarded as a essential infrastructure to share knowledge. However, considering most of information leakage is sprung up by insider of organization, it is considered to provide countermeasure to protect illegal use from information leakage. The purpose of this paper is to establish digital information security system through design of document and manage digital information assets safely through electronic document security system protecting illegal leakage of digital information assets.

This research proposed the necessary capability of cyber security professional personnel for cyber security education and training. Cyber security professional personnel were required specialized capability because the curriculum of cyber security education and training is structured around practice and training. Based on the knowledge, skills, and attitudes of professors, we derive candidate capabilities and index through the results of precedent research. As a result, we derived capability such the candidate capability group as teaching qualification, expert knowledge, practical ability, lecture ability, and research ability, and detailed capability index was derived accordingly. Finally, based on the questionnaire results of the professors related to the information security, it was determined that the capability required for the cyber security education and training professional personnel were expert knowledge, practical ability, and lecture ability. Among the capabilities, executive ability means that they have to fulfil abundant executive experience due to the high proportion of practical training due to the characteristics of cyber security education and training.

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.

This explorative study examines the difference in firm performance according to the adoption of the core technology of the Fourth industrial revolution, including artificial intelligence(AI), internet of things (IoT), cloud computing, and big data technology. Additionally, we investigate the importance of internal organizational structure exclusively responsible for information security. We analyze unique microdata offered by the Korea Information Society Development Institute to examine the impact of the adoption of the new technologies and the existence of organizational structure for information protection on firm performance, i.e., firm sales. By considering the core information technology as powerful knowledge assets, we argue that the adoption of such technology leads firms to have comparative advantage comparing to the competitors. Also, we emphasize the need to consider the organizational structure suitable for information security, which can become a structural asset of a firm.

스마트폰 보급의 확산으로 모바일 금융 서비스 이용자 수는 증가하고 모바일 금융 보안에 대한 중요성이 증가되고 있는 실정이지만 해마다 다양해지는 금융 공격에 대비하기는 결코 쉽지 않다. 최근 주로 사용되고 있는 금융 보안 인증 방식인 OTP(One-Time Password)는 세션 공격에 대한 보안 대비가 가능하지만 차별화된 OTP 생성 메커니즘을 적용하는 것이 힘든 단점이 있다. 본 연구에서는 이러한 기존 방식의 문제점을 해결하기 위해 확장된 OTP 메커니즘을 이용한 새로운 금융 보안 방식을 제안하고자 한다. 제안 방식은 센서 네트워크를 금융 보안 알고리즘에 적용시킨 위치 기반 동기화 방식의 OTP 생성 메커니즘으로서 다양한 금융 해킹과 공격 기법에 대비가 가능하다.
