The "Risk management" and "Security monitoring" activities for cyber security are deeply correlated in that they prepare for future security threats and minimize security incidents. In addition, it is effective to apply a pattern model that visually demonstrates to an administrator the threat to that information asset in both the risk management and the security system areas. Validated pattern models have long-standing "control chart" models in the traditional quality control sector, but lack the use of information systems in cyber risk management and security systems. In this paper, a cyber Security Risk Monitoring (SRM) system that integrates risk management and a security system was designed. The SRM presents a strategy for applying 'security control' using the pattern of 'control charts'. The security measures were integrated with the existing set of standardized security measures, ISMS, NIST SP 800-53 and CC. Using this information, we analyzed the warning trends of the cyber crisis in Korea for four years from 2014 to 2018 and this enables us to establish more flexible security measures in the future.

Distributed ledger technology, which is attracting attention as an emerging technology related to the 4th Industrial Revolution, is implemented as an open source based distributed ledger technology system and widely used for development with various applications (or services), but the security functions provided by the distributed general ledger system are very insufficient. This paper proposes security enhancements for distributed ledger technology systems based on open source. To do so, potential security threats that may occur under running an open source based distributed ledger technology systems are identified and security functional requirements against the security threats identified are provided by analyzing legislation and security certification criteria (ISMS-P). In addition, it proposes a method to implement the security functions required for an open source based distributed ledger technology systems through analysis of security functional components of Common Criteria (CC), an international standard.

Currently, Many Cyber Security Centers(CSC) are established and being operated in our country. But, in the absence of indicators to evaluate activities of the Managed Security Service(MSS), We can't identify the CSC's level of overall job performance. Therefore, we can't derive strengths and weaknesses from the CSC. From these reasons, The purpose of this research is to develop an objective indicator to evaluate activities of the MSS. I studied both international and domestic Information Security Management System(ISMS) as related standards(ISO/IEC 27001, G-ISMS). Moreover, I analysed the NIST Computer Security Incident Handing Guide and the Incident Management Capability Metrics(IMCM) of Carnegie Mellon Software Engineering Institute(SEI). The implications for this analysis and domestic hands-on experience are reflected in the research. So I developed 10 evaluation domains and 62 detail evaluation items. This research will contribute to our understanding the level of the CSC's job performance.

The rapid spread of smart phone in recent years changes not only personal life but also work environment of organizations. Moreover, smart phone provoke service combination between industries and transit the digital paradigm in our society because of the character that anyone can develop or use the application of smart phone. Under these circumstances, the government hastens the construction of mobile-government in order to improve national services and communication with people. However, since security threats on smart phone become more critical recently, we should hurry the counter measures against mobile threats or we will face obstacles to the activation of mobile-government. On this article, we suggest the methods of information security and the Mobile-government Information Security Management System(M-ISMS) on the smart phone use environment for building up the secure and convenient mobile system in the national institution.

Recently, research on solving problems that have introduced the concept of smart city in countries and companies around the world is in progress due to various urban problems. A smart city converges the city's ICT, connects all the city's components with a network, collects and delivers data, and consists of a supply chain composed of various IoT products and services. The increase in various cyber security threats and supply chain threats in smart cities is inevitable, in addition to establishing a framework such as supply chain security policy, authentication of each data provider and service according to data linkage and appropriate access control are required in a Zero-Trust point of view. To this end, a smart city security model has been developed for smart city security threats in Korea, but security requirements related to supply chain security and zero trust are insufficient. This paper examines overseas smart city security trends, presents international standard security requirements related to ISMS-P and supply chain security, as well as security requirements for applying zero trust related technologies to domestic smart city security models.

ISO의 정보보호관리 표준은 ISO/IEC JTC1/SC27 WG1에서 표준화를 진행하고 있으며, 현재까지 제정된 정보보호관리 표준으로는 ISO 13335 MICTS와 ISO 17799 Code of practices for information security management 등이 있다. ISO 13335는 정보보호관리 모델 및 기술에 대한 가이드를 제공하는 표준이고, ISO 17799는 정보보호관리 통제에 대한 가이드를 제공하는 표준이다. 최근 동향으로는 ISMS(Information Security Management Systems)국제표준화 작업이 시작될 것으로 예상되며, WG1에서 작업 중인 정보보호관리 표준 간 유사성을 배제하고 통합된 체제를 만들기 위한 로드맵 작성 작업이 진행 중에 있다. 인터넷의 확산과 정보화의 역기능 증가에 따라 능동적인 정보보호관리체계의 수립을 위하여, 우리나라도 정보보호관리 표준의 제정 과정에 적극적으로 참여할 뿐 아니라 국내 많은 조직에서 정보보호관리 표준이 적용되어 국가적인 정보보호관리 수준이 향상될 수 있도록 할 필요가 있다.

The kallikrein-kinin system affects regulation of blood pressure, and genes encoding for the components of this system have been considered as good candidates for hypertension. To evaluate the relationship between genetic polymorphisms of candidate genes involved in this system and hypertension, we performed case-control studies using genetic markers in Korean normotensives and hypertensives, respectively. By association study, there was a marginal association with hypertension in AA genotype distribution of A1789G polymorphism in the hKLK1 gene (P=0.0754). Thus, this genetic polymorphism may weakly contribute to the susceptibility to hypertension in Koreans. We also observed that significant linkage disequilibrium exists among three polymorphic sites in the hKLK1 gene studied, suggesting that the three genetic polymorph isms can be useful as genetic markers in clinical association studies. Further studies using larger sample sizes and more genetic markers will be needed to clarify genetic influence of kallikrein-kinin system for hypertension.

Hypertext is a web form consisted of HTML(hypertext markup language) which is used in Internet. Hypertext in costume is the product of modem industrial society. Hypertext is not a mechanical technique that enlarges external capacity of human beings. It is rather a motif that extends the internal ability of human beings. It brings about the social innovation by extending the expression realm of costume and providing the various views of recognition. This study regards costume not as an artistic work but as a text which interacts in the open relationship of human body, society and culture and causes dynamic generation of meaning. This study distinguishes Plasticitic Characteristics of Hypertext in Costume with intertextuality, rhizome, interactivity in the structural characteristics of hypertext which is a typical trait of digital culture of openness and variousness. In conclusion, this study clarified plasticitic value of modem costume, which expresses vague isms and the pargidm of multi-typed culture most sensitively and condretley, and expressional forms in relation with the structural characteristics of hypertext.
