The purpose of this study is to understand the cybersecurity policies and critical infrastructure protection of the United States through analyzing Donald Trump's administration executive orders, the national cyber strategy, and the legislation. The analysis has three findings. First, the Department of Homeland Security (DHS) became a main agent in the cybersecurity while the role of the White House was reduced. Second, Trump's administration expanded its role and mission in the policy area by extending the meaning of critical infrastructure. Third, in the case of cyber threats, the government can be involved in the operation of critical infrastructures in the private sector. The opinions of the professional bureaucrats and DHS were more reflected in the direction of the cybersecurity policy than those of the White House. In contrast to Barack Obama's administration, the Trump administration's cybersecurity strategies were not much studied. This study provides insights for improving cybersecurity policies and critical infrastructure protection.

정보통신 기술 발전과 함께 VTS시스템도 비약적으로 발전하고 있다. 특히 해상교통관제의 수요자 증가와 서비스 질 향상을 위해 외부 네트워크의 연계를 통한 정보공유와 교환의 필요성이 지속 증가하고 있다. 따라서 VTS 시스템 간 및 외부 시스템과의 연계와 관련 정보보안의 취약점이 드러날 개연성이 높아졌다. 따라서 본 연구에서는 국가 주요 기반 시설로서의 VTS 시스템의 정보보안의 중요성과 현 취약점을 살펴보고 앞으로 개선해야 할 점을 고찰해 보았다.

우리나라의 무역 활동을 처리하는 항만은 국가 주요시설로 보안에 만전을 기하고 있다. 그러나 항만의 면적이 넓고 복잡하기 때문에 사각지대가 존재하고 사각지대에서의 불법행위 단속 건수는 매년 증가하고 있다. 이에 항만의 보안 강화를 위한 대책이 필요하다. 본 논문은 항만의 상황을 이동형 CCTV에 부착된 IoT 센서들로 인식하여 YOLOv5 딥러닝 모델로 분석한 후 웹 대시보드에 시각화하는 항만 보안 시스템을 제안한다. 이동형 CCTV는 특정 위치로 직접 이동할 수 있어 거리에 따라 해상도가 낮아지는 기존 CCTV의 단점을 보완할 수 있다. 또한 해당 시스템은 주변에서 쉽게 구할 수 있는 장비들과 오픈소스 라이브러리를 활용하기 때문에 다른 보안장비들에 비해 효율적인 비용으로 높은 보안 효과를 얻을 수 있다는 강점을 지닌다. 본 시스템은 항만시설뿐 아니라 군사시설, 물류시설 등 보안을 중요시하는 다른 분야에 확대 적용될 수 있다는 점에서 의의가 있다.

This study aimed to asses the relationship between shoppers' security need sufficiency and customer satisfaction on the quality of security services in Shopping Mall. This study gathered data from 485 citizen in five shopping centres at KyungKi areas. Collected data was analysed by factor analysis, reliability analysis, path analysis and multiple regression analysis with SPSS WIN 16.0. The results of the study yielded the following four perspectives. First, secure equipment and the service quality of security officers in the shopping malls have a decisive effect on customers psychological stability and crime prevention. Second, they are a strong influence upon customer satisfaction and operational security. Especially, the professionalism of the staff has a marked effect. Third, the service quality of security officers and secure equipment in the malls have an effect on operational security services and efficiency of secure services. Finally, this dissertation showed that the quality of secure equipment services and officers' mild In summary, the conclusion of this study is that secure equipment service, officers' mild manner and professionalism of the security officers affect the customer satisfaction measurement directly. They also affect customer satisfaction through psychological stability and the prevention of crime indirectly. In other words, the good quality of security in the shopping centres affects the using of facilities definitely.

As information processing technology develops with the trend of the times, the possibility of cyber threats to nuclear facilities is increasing. In the 2000s, there was a growing perception that cyberattacks on nuclear facilities were needed, and in fact, a cybersecurity regulatory system for nuclear power plants began to be established to prepare for cyberattacks. In Korea, in order to prepare for cyber threats, in 2013 and 2014, the Act on Protection and Radiation Disaster Prevention, Enforcement Decree, and Enforcement Rules of Nuclear Facilities, etc., and notices related to the Radioactive Disaster Prevention Act were revised. In 2015, domestic nuclear operators prepared information system security regulations for each facility in accordance with the revised laws and received approval from the Nuclear Safety Commission for implementation of information system security regulations divided into seven stages. In 2019, a special inspection for step-by-step implementation was completed, and since 2019, the cybersecurity system of operators has been continuously inspected through regular inspections. In this paper, we present some measures to build improved training to suit the steadily revised inspection of the nuclear facility cybersecurity system to counter cyber threats to the ever-evolving nuclear facilities.

"원자력시설 등의 방호 및 방사능 방재 대책법"(이하 '방사능방재법')에 의거하여 한국원자력통제기술원은 원자력안전위원회로부터 원자력시설의 사이버보안 규제 업무를 위임받아 수행하고 있으며, 그 중 위협평가 업무를 통해 최신 사이버 위협 사례를 분석하여 사이버보안체제의 기준이 되는 설계기준위협을 설정하고 원자력사업자의 이행 여부를 평가하고 있다. 위협평가의 첫 단계로 방사능방재법에 따라 3년 마다 최신 사이버 위협 사례를 조사 및 분석하여야 하며, 사이버 위협분석 자료는 원자력사업자가 방호해야하는 최대 위협 수준인 설계기준위협 설정에 사용된다. 본 논문에서는 최근 3년간 원자력시설과 같은 중요시설 대상으로 발생한 사이버 위협 사례를 분석하였으며, 향후 분석 자료를 바탕으로 위협평가에 활용하고자 한다.

Methods that industrial spies use to smuggle core technology out are becoming more intelligent, technological, and complex, thus resulting in more serious damages. In particular, defense industries in which involve national core technology as well as institutions including labor force are industries that are in a greater need of the convergence security. Defense Industry develops, experiments, and produces defense security supplies for national security protection. Defense industry involves a number of security elements such as military secret, industrial secret, core technology labor force, defense industry supply, critical national facility, and information communication system. Defense industry security is a complex of military security and industrial security which is convergence security that integrates all security elements of defense industry. Therefore, defense industry security is a typical ideal model for convergence security. Research on defense industry security is relatively insufficient compared to research of security in other industrial fields. In order to prevent core technology of denfese industry from leaking and to protect technical professionals and institutions, research and action on defense industry security from convergence security perspective are therefore essential at this point of time.

2023년 10월, 공통 취약점 평가체계의 신규 버전이 8년 만에 출시되었다. 공통 취약점 평가체계는 취약점의 심각도 점수 및 특성 정보를 제공하는 시스템으로, 취약점 관리활동의 바로미터로 활용되고 있다. 그러나 기존 공통 취약점 평가체계의 점수는 기반 시설에서의 실제 취약점 악용 가능성과의 불일치 및 운영 환경의 특성을 반영하지 못하는 한계점이 존재한다. 본 연구에서는 미국 등을 비롯한 국외 기반시설의 취약점 정량화 평가체계 선행 연구 및 적용 현황등을 분석하고, 이번에 신규 출시된 공통취약점 평가체계의 주요한 변경사항을 다룬다. 더불어 국내 원자력 시설의 운영 특성을 반영하여 개발되고 있는 취약점 정량화 평가시스템에 대해 소개한다.

Cyber attacks targeting critical infrastructure are on the rise. Critical infrastructure is defined as core infrastructures within a country with a high degree of interdependence between the different structures; therefore, it is difficult to sufficiently protect it using outdated cybersecurity techniques. In particular, the distinction between the physical and logical risks of critical infrastructure is becoming ambiguous; therefore, risk management from a comprehensive perspective must be implemented. Accordingly, as a means of further actively protecting critical infrastructure, major countries have begun to apply their security and cybersecurity systems by design, as a more expanded concept is now being considered. This proactive security approach (CSbD, Cybersecurity by Design) includes not only securing the stability of software (SW) safety design and management, but also physical politics and device (HW) safety, precautionary and blocking measures, and overall resilience. It involves a comprehensive security system. Therefore, this study compares and analyzes security by design measures towards critical infrastructure that are leading the way in the US, Europe, and Singapore. It reflects the results of an analysis of optimal cybersecurity solutions for critical infrastructure. I would like to present a plan for applying by Design.
