Cyberspace is becoming increasingly important. Incidentally, there exist possibilities of the industrial secrets leaked, cyber attacks, privacy protection problems. In addition, there are growing concern of cyber war between nations. Thus potential hazards in cyberspace and the extent of damage are getting bigger. Therefore, a systematic understanding of cyber damage and damage scale is very important and damage estimation method should be developed to establish solid cyber protection system. In this study, current and potential damage types are understood and damage scales are surveyed based on the analysis of existing studies and try to develop a reasonable methods to estimate economic effects of cyber protection.

As ICT convergence is progressing in all industrial fields and creating the global ecosystem of the supply chain is accelerating, supply chain risk related with cyber area are also increasing. In particular. the supply chain of ICT products is very complex in terms of technical and environmental factors to be managed, so it is vert difficult to transparently manage the entire life cycle. Accordingly, the US, UK, and EU, etc. are conducting and establishing cyber supply chainsecurity-related research and policies for ICT product supply chains. Korea also has the plan to establish management system to secure the supply chain of major ICT equipment as a task in the basic plan of the national cybersecurity strategy announced in 2019, but there is no concrete policy yet. So, In this paper, we review the cyber supply chain security management system in the United States and present a supplementary way to the National Information Security Manual in Korea from the perspective of cyber supply chain security. It is expected that this will serve as a reference material for cyber supply chain measures that can be introduced in domestic information security field.

As the post-cold war era and globalization go on, national security problems which were not traditional national security problems such as terrorism, crime, environmental disasters, economic crises, cyber-terrorism, diseases, and energy problems threat humanity and nations and demands changes. Also, with the change, the concept of "big government" has emerged as the role of nation expanded. The modern society sees every country change from small government to big government in order to realize the establishment of welfare state. A comprehensive interpretation of security is needed in order to comprehensive protection of citizens beyond outside invasion such as crime, new disaster, terrorism. In Korea, incidents such as Cheonan-Ham, Yeonpeyong-Do, foot-and-mouth disease, Ddos terrorism, pirates hostages, mad cow disease, AI are happening and the humanitarian support for North Korea and the summit of South and North Korea are at a standstill. Also, National emergency management system, comprehensive emergency management center, countrol tower, national security system, cooperation with citizens, establishment of legal and institutional system are needed. The importance of this research is on the reestablishment of new national security and emergency management system according to the comparison between the national security and counter-terrorism system of Korea and that of the United States which is a leading country in this field. Also, the establishment of national emergency management act is needed as a statute for effective function as currently various laws and administrative organizations are dispersed.

국가 4차 산업혁명의 성장 동력으로 데이터 경제가 주목받고 있으며, 현(現)산업계는 초연결, 초지능, 초융합 사회로 진보하고 있다. 이와 같은 환경에서는 산업군 간의 경계가 사라지고 전방위적인 상호 유기적인 복합 생태계를 구성하게 된다. 따라서 사이버 보안사고 발생 시 단순 데이터 탈취 정도에 국한되지 않고 안보, 생명, 국가 경제 등에 돌이킬 수 없는 손실을 끼칠 것으로 예상된다. 그러나 현재 사이버 보안의 각종 제도 및 법령 등은 중복·혼재되어 있거나 특정 산업군에 적용하기에는 일부 미흡한 요소도 존재한다. 본 논문에서는 이와 같은 문제점을 개선하고 전방위적인 보안거버넌스를 달성하기 위한 통합 사이버 보안 프레임워크 구축 방안을 제언한다.

Recent DDoS attacks and private informations leaked show that everyday life is interwoven with cyberspace and we are becoming more vulnerable to cyber attacks. Therefore, a systematic understanding of cyber damage structure is very important and damage loss estimation method should be developed to establish solid cyber security protection system. In this study, economic loss caused by cyber attacks are surveyed based on the analysis of existing studies and try to develop a reasonable methods to estimate economic effects of cyber security protection in Korea. Potential economic loss of Korea by cyber attacks may be situated between 10 billion and 40 billion dollars. But more sophisticated system should be established to estimate economic effects of cyber protection for proper policy decision making.

본 연구에서는 미국의 국가핵심기반보호제도의 변화에 대해 고찰하고 시사점을 도출한다. 이를 위해 9/11 테러 공격 이후 국가핵심기반보호계획(National Infrastructure Protection Plan)을 중심으로 관련 법률 및 제도와 조직변화를 추적하고 고찰하였고, 이들의 관계를 도식화하여 타임라인(timeline)분석을 실시하였다. 본 연구를 통해 국토안보대통령령-8호(HSPD-8), 대통령령-21호(PDD-21), 사이버보안과 핵심기반법(Cybersecurity & Infrastructure Act)등의 관련 법제 변화를 통해 총 3가지 버전의 NIPP이 있음을 확인할 수 있었으며, 2018년에 사이버보안과 주요인프라청(CISA)이 창설되어 국가핵심기반보호제도업무를 이곳으로 이관하여 운영되고 있음을 알 수 있었다. 또한 국가핵심기반을 보는 관점이 9/11 테러 공격 이후 주요 핵심기반 보호(Protection)에서 주요핵심기반의 복원력(Resilience)제고로 변화하고 있음을 도출하였다.

Recently, cyber attacks against public communications networks are getting more complicated and varied. Moreover, in some cases, one country could make systematic attacks at a national level against another country to steal its confidential information and intellectual property. Therefore, the issue of cyber attacks is now regarded as a new major threat to national security. The conventional way of operating individual information security systems such as IDS and IPS may not be sufficient to cope with those attacks committed by highly-motivated attackers with significant resources. As a result, the monitoring and control of cyber security, which enables attack detection, analysis and response on a real-time basis has become of paramount importance. This paper discusses how to improve efficiency and effectiveness of national cyber security monitoring and control services. It first reviews major threats to the public communications network and how the responses to these threats are made and then it proposes a new approach to improve the national cyber security monitoring and control services.

In the era of the Fourth Industrial Revolution, digital transformation to increase the effectiveness of industry is becoming more important to achieving the goal of industrial innovation. The digital new deal and smart defense are required for digital transformation and utilize artificial intelligence, big data analysis technology, and the Internet of Things. These changes can innovate the industrial fields of national defense, society, and health with new intelligent services by continuously expanding cyberspace. As a result, work productivity, efficiency, convenience, and industrial safety will be strengthened. However, the threat of cyber-attack will also continue to increase due to expansion of the new domain of digital transformation. This paper presents the risk scenarios of cyber-attack threats in the Fourth Industrial Revolution. Further, we propose a preemptive intrusion response model to bolster the complex security environment of the future, which is one of the fundamental alternatives to solving problems relating to cyber-attack. The proposed model can be used as prior research on cyber security strategy and technology development for preemptive response to cyber threats in the future society.
