In this study, I analyzed the increased threat of cyber warfare and the threat of reality about what is happening around the currently. And to prepare for it, I proposed the fact how main developed countries deal with cyber warfare. Also, I presented North Korea's cyber warfare threat which is equipped with world's top 3 cyber warfare performance and the way how their strategy influence to South Korea's national security. Moreever, I studied the existing North Korea's cyber warfare threat and the way how, how South Korea deal with it and prepare to against expected threat of cyber warfare in future.

There have been many efforts to reduce prejudice and discrimination against people with mental illness in our community. Studies have shown that the threat to people with mental illness is a important factor. In this study, we focused on contact experience and sense of community that are believed to influence both realistic and symbolic threat We looked the differences in threat depending on the type of contact(family, friends/coworker, public places, no contact) with people with mental illness. Next, if there is contact experience, we questioned that the quality of the experience could influence the threats in all types of contact. Finally, could contact experience and sense of community affect the threats? The total of 465 respondents were surveyed in this study. The result showed that the realistic threat were not different depending on the types of contact, but that the symbolic threat were more higher people with no-contact experience than people with contact experience. The quality of experience had a significant effect on both threats, except in the case of the family contact on realistic threat. Lastly, sense of community was analyzed as a significant variable for both realistic and symbolic threats. Based on these results, we discussed the impact of contact and sense of community and implications of this study.

최근 기존 폐쇄적 제어시스템 환경에서 네트워크를 통해 연결되는 개방형 제어시스템으로 변화하는 등 전자적 제어시스템의 정보통신기술에 대한 의존도가 더욱 심화되고 있다. 전자적 제어시스템은 효율성을 높이고 사회 전반의 편의성을 증진시켰으나, 정보통신기술의 취약성이 전이됨에 따라 안전하게 보호되어야할 제어시스템은 위협에 노출되고 있는 것이 현재 상황이다. 전자적 제어시스템 침해사고 발생 시 제어시스템의 특성 상 많은 피해 및 사회적 혼란을 초래할 수 있기 때문에, 국가 차원에서 법률적인 보호조치가 필요하다. 국내에서는 2001년 "정보통신기반 보호법"이 시행되어 국가정보통신기반시설에 대한 보호 및 사고 대응을 규정하고 있다. 본 논문에서는 실제 발생한 제어시스템 침해사고를 분석을 통해 전자적 제어시스템의 위협요인 및 이에 따른 대응방안을 모색한다. 또한 제어시스템 위협에 가장 선도적으로 대응하고 있는 미국의 법제 분석을 통해 전자적 제어시스템 침해 위협에 따른 법적 대응방안에 대하여 연구하고자 한다.

Based on the network infrastructure advanced in the information knowledge society, the structure of computer net work is operated by establishing the composition of network in various forms that have secured the security. In case of computer network of national/public organizations, it is necessary to establish the technical and managerial securit y environment even considering the characteristics of each organization and connected organizations. For this, the im portance of basic researches for cyber training by analyzing the technical/managerial vulnerability and cyber threats based on the classification and map of cyber threats according to the characteristics of each organization is rising. T hus, this study aims to analyze each type of external/internal cyber threats to computer network of national/public o rganizations established based on the dualistic infrastructure network of internet and national information network, a nd also to present the cyber threat framework for drawing the elements of cyber security training, by drawing and analyzing the actual elements of cyber threats through the case-based scenario.

Lately smartphone uasage is increasing and many Internet of Things (IoT) devices support wireless communications. Accordingly, small base stations which called femtocells are supplied to prevent saturation of existing base stations. However, unlike the original purpose of the femtocell with the advanced hacking technologies, Vulnerability such as gaining the administrator authority was discovered and this can cause serious problems such as the leakage of personal information of femtocell user. Therefore, identify security threats that may occur in the femtocell and it is necessary to ways for systematic vulnerability analysis. In this paper, We analyzed the security threats that can be generated in the femtocell and constructed a checklist for vulnerability analysis using the Threat Modeling method. Then, using the constructed checklist provides a scheme that can improve the safety of the femto cell through the actual analysis and taken the results of the femtocell vulnerabilities analysis.

Recently, the introduction of Cloud Managing Security Services System to respond to security threats in cloud computing environments is increasing. Accordingly, it is necessary to analyze the security requirements for the Cloud Managing Security Services System. However, the existing research has a problem that does not reflect the virtual environment of the cloud and the data flow of the Cloud Managing Security Services System in the process of deriving the requirements. To solve this problem, it is necessary to identify the information assets of the Cloud Managing Security Services System in the process of threat modeling analysis, visualize and display detailed components of the cloud virtual environment, and analyze the security threat by reflecting the data flow. Therefore, this paper intends to derive the security requirements of the Cloud Managing Security Services System through threat modeling analysis that is an improved existing research.

In this paper, we analyzed the characteristics of cyber attacks and major threat scenarios that could occur around intelligent building management Systems(IBS) by cyber attack security threats against cyber physics systems. Generally determined that lowering the likelihood of aggression against predictable threats would be a more realistic approach to attack response. The countermeasures against this need to be applied to multi-layered defense systems, and three alternatives were proposed: preliminary cyber safety diagnosis for protection targets and the establishment of mobile security control systems.

Related to the situation on the Korean Peninsula, by North Korea's threat of war the tension escalates and serious crisis continues. The purpose of this study is to evaluate the subjective perception which the residents of South Korea feel about North Korea's threat of war through a Q methodological analysis framework. In the result of the study, for the North Korea's threat of war the South Korean's recognition type is analyzed into four type such as 'non-reactive', 'fearreactive', 'psychological anxiety' and 'cynical ignorance type'. First, the No. 1 type 'non-reactive' does not empathize with North Korea's threat of war itself, and second type 'fear-reactive' have uneasy feeling like that 'What would happen as things go' and feel a sense of crisis about the North Korea's threat of war. The third type 'psychological anxiety' is type which feels that due to North Korea's threat of war inter-Korean relations is in the crisis. Finally the fourth type 'cynical ignorance' think that North Korea's threat of war is bluffing and also North Korea is like a shepherd boy. The reason to apply Q-methodology in this study is to make it possible to a more in-depth approach to subjective perception and threat of psychological meaning for the threatening message of study participants.
