Mankind has been living in the third millennium of a new era for 15 years. Today he realized that he was on a tiny planet with not much space. The 20th century laid bare its global consequences in all its horror.. According to the Stockholm International Peace Research Institute, more than 30 armed conflicts are recorded on the planet every year, leading to the death of more than 1,000 people during the year. Over the past 15 years, the total number of deaths as a result of military actions in such conflicts has also increased: more than 17 thousand people - in 2002 to more than 22.5 thousand - in 2011. 2022, in turn, became the beginning of a new round of military history, bringing changes in the social, environmental, agro-industrial, economic and other spheres not only in Ukraine, but also in all countries of the civilized world. As a result of the study, the most significant impact of the negative factors of the war, namely the economic, legal, regional and environmental aspects, was identified and analyzed.

With the recent increase in users' dependence on the Internet and the spread of various IT devices, the influence of information security on the users' has expanded compared to the past. Therefore, it is expected to have an increased influence on information security in personal life. In addition, as the intrusion factors that threaten security continue to become more advanced and diversified (eg., fake news, cyberbullying, identity theft), the need for nurturing information security experts is increasing. Furthermore, not only corporate information security workers, but also all individuals, cannot be free from the threat of information security. Therefore, it is necessary to prepare various information security education to improve information security awareness and induce proactive information security behaviors. In this study, characteristics of domestic and foreign information security education courses are analyzed and provide a standardized framework for information security education applicable to the domestic environment.

For the last 70 years, the U.S.-led bilateral security system, or "Hub-and-Spokes" system, has been applied to Northeast Asia, and the system has been successfully settled in terms of stability and economic achievements of the region. Given the increasing complexity of the security environment of East Asia, it is plausible to consider the possibility of a security system shift from bilateral alliances to collective security. In order to analyze the driver of collective security system, this study developed three factors of formation and development of collective security system - main threat, intensity of the threat, and confidence among countries in the system - by reviewing international political theories related to security cooperation. Comparing the formation, development, and achievements of NATO and SEATO, the study figures out that the existence of the main threat, the high intensity of the threat, and the strong confidence among countries in the security system are the primary drivers for a successful collective security system. Based on the result, the study also analyzed the possibility of a security system shift in East Asia. Considering contemporary international conflicts such as U.S.-China strategic competition, Russia-Ukraine War, and growing threats posed by North Korean nuclear and missiles, the study anticipates that the necessity of a collective security system that will replace the current security system of the region would arise. Still, although some issues between countries should be overcome, the growing intensity of the threats will promote cooperation among countries by improving their confidence.

With respect to the factors affecting information security awareness and behavior, the study of the relevance of the concept of optimistic bias is actively used in psychology. In other words, this study examines whether the optimistic bias of individuals affects information security in the field. In this sense, this study attempted to demonstrate the relevance of optimistic bias in information security behavior and awareness. A questionnaire survey was conducted targeting 111 people engaged in domestic private enterprises. The survey results showed that this personalized optimistic bias exists because of empirical factors related to personal security. Optimistic bias affects the security awareness information. The greater the optimistic bias, the lower the awareness and recognition of information security. In other words, optimistic bias affects information security awareness. Reducing the effects of optimistic bias is expected to reduce information security incidents, such as information leakages. However, the variety of information related ethical activities of a company did not have any effect on the information security awareness. Most previous studies have only examined the effect optimistic bias in the field of health. Therefore, this study fills an important gap in research in IT.

This study is composed of a convergence research design plan as the necessity of information security field dealing with human factors are raised. The purpose of this study is to analyze the effectiveness of the aspect of information security on the cognitive process related to security policy. The research method consisted of the cross-design of the availability dimension and the culture dimension, and the information security process was measured with information security awareness, response efficacy, compliance behavioral intention, and information security behavior. As a result of the study, the dimension of availability had a significant effect on response efficacy, and it was found that the influence of the case-based condition was greater than that of the statistics-based condition. The cultural dimension had a significant effect on information security awareness, response efficacy, compliance behavioral intention, and information security behavior, and the influence of the homogeneity condition was found to be greater than that of the diversity condition. The proposed research model was verified as a multiple mediation model reconstructed with measurement variables. In addition, the discussion describes the necessity of an information security strategy in consideration of individual factors and organizational characteristics.

Strategies have to be employed in information systems security in order to build and operate systems for information systems security in effective and structured manner. It is also essential for the entire organization to participate for successful implementation of the strategies and making them work. Current researches on information systems security strategy in organizations, however, have mainly been focused on deployment and operation of countermeasures based on strategic thinking and decision. In consequence, it is lack of research on overall frame for containing consideration factors required for moving and leading the whole enterprise for the holistic security purpose. Therefore, this paper proposes a framework for use in establishment of organization-wide information systems security strategies based on the concept of grand strategy from the traditional strategy research and on the four dimensional features of it.

The purpose of this study is to identify the effects of organizational conflict stages and job withdrawal intention of information security organizations. We applied Pondy's conflict theory and analyzed the case of information security workers in public enterprises. We found that the more information security workers emotionally accept the potential factors of organizational conflict, the higher the intention of job change of information security practitioner. On the other hand, the perception mechanism has a moderating effect of lowering the job change-out probability. The result of this study is expected that the manager of the organization will be able to utilize the conflict in the organizational direction.
