On the one hand, the 4th Industrial Revolution provides a positive opportunity to build a new civilization paradigm for mankind. However, on the other hand, due to the 4th Industrial Revolution, artificial intelligence such as 'Goggle Alpha Go' revolutionized and even the human ability was replaced with a 'Silicon Chip' as the opportunity to communicate decreases, the existence of human beings is weakened. And there is a growing concern that the number of violent crimes, such as psychopath, which hunts humans as games, will increase. Moreover, recent international terrorism is being developed in a form similar to 'Psychopathic Violent-Crime' that indiscriminately attacks innocent people. So, the probability that terrorist organizations abuse the positive effects provided by the Fourth Industrial Revolution as means of terrorism is increasing. Therefore, the paradigm of aviation terrorism is expected to change in a way that attacks airport facilities and users rather than aircraft. Because airport facilities are crowded, and psychopathic terrorists are easily accessible. From this point of view, our counter terrorism system of aviation has many weak points in various aspects such as: (1) limitations of counter-terrorism center (2) inefficient on-site command and control system (3) separated organization for aviation security consultation (4) dispersed information collection function in government (5) vulnerable to cyber attack (6) lack of international cooperation network for aviation terrorism. Consequently, it is necessary to improve the domestic counter terrorism system of aviation so as to preemptively respond to the international terrorism. This study propose the following measures to improve the aviation security system by (1) create 'Aviation Special Judicial Police' (2) revise the anti-terrorism law and aviation security law (3) Strengthening the ability respond to terrorism in cyberspace (4) building an international cooperation network for aviation terrorism.

Since the September 11, 2001, the United States has shift their national security policy for homeland from preventing or/and reducing foreign threats to ensuring domestic security. We learned from recent incident, 1.25 Internet Disaster, that it is urgent to establish cyber security policy for our nation. In this paper; therefore, I analyze the US homeland security policy, the Homeland Security Act of 2002 establishment, and cyber security-related part in this act.

사이버테러는 전세계적으로 시공간을 초월하여 동시다발적 공격이 가능하고 발생시각, 발원지, 침입자 추적 등이 어려우며, 한 곳의 피해가 다른 곳으로 대규모 확산이 우려되고 효율적인 차단 및 복구에도 어려움이 가중되고 있다. 이에 본 논문에서는 행정정보인프라의 불법침입에 대한 즉각적인 대응체계와 사이버테러의 사전 예방을 위한 정부고속망의 연결기관에 대한 보안정보제공 및 침해사고 공동대응 체제를 갖춘 정부차원의 정부정보공유분석센터의 효율적인 구축 방안을 제안한다.

Todays, the more information technologies(IT) like internet is developed, the more main facilities of individuals and social organizations get deeply involved in IT. Also, the trend of cyber threats such as internet worms and viruses is moving from local pc attacks to IT infrastructure attacks by exploiting inherent vulnerabilities of IT. Social organizations has a limit to response these attacks individually, and so the systematic coordinate center for social organizations is necessary. To analyze and share cyber threat information is performed prior to the construction of the coordinate center. In this paper, we survey domestic alert systems for cyber threats of related organizations and companies, and then classify them into two categories by the range of threat assessment: global alert systems for global If infrastructure and individual alert systems for each threat. Next, we identify problems of domestic alert systems and suggest approaches to resolve them.

전력시스템에 IT를 결합한 스마트그리드에 대한 연구가 최근 활발히 진행되고 있다. 스마트그리드 중 전력시스템의 핵심이라 할 수 있는 전력시스템 제어센터 간 통신을 담당하는 것이 ICCP 프로토콜이며, 주로 중앙급전소와 지역급전소간의 전력망 정보들을 교환하는데 사용되고 있다. 이 프로토콜은 단지 전력망의 정보교환 뿐 아니라 전력기기제어 기능도 가지고 있다. ICCP 프로토콜은 TCP/IP 프로토콜을 기반으로 동작하기 때문에 잠재적으로 다양한 형태의 사이버 공격이 가능하다. 또한 이 프로토콜을 사용하는 중앙급전소의 경우 주요 국가기반시설로써 사이버테러에 더욱더 공고한 대응체계를 갖추어야 할 필요가 있다. 현재 ICCP 프로토콜을 사용하는 통신 구간은 일반적으로 외부 네트워크와 분리되어 그 안전성을 담보하고 있지만, 네트워크 분리를 통한 보안성 향상 기법이 체계적인 관리와 함께 수반되지 않으면 인적 취약성이나 새로운 형태의 모바일 기기를 통한 물리적 취약성에 지속적으로 노출 될 수 있는 잠재적 위험을 내포하고 있다. 따라서 이러한 보안 사고의 잠재적 발생 가능성으로 인해 외부네트워크와 분리된 제어센터들도 향후 더욱더 높은 수준의 보안 기술을 적용할 필요성이 강조되고 있다. 본 논문에서는 전력 제어센터 사이에서 사용되고 있는 ICCP 프로토콜의 사이버 보안 현황에 대해 살펴보고 해당 프로토콜의 보안 위험성과 이에 대한 대응방안을 고찰한다.

The NH-NongHyup network and servers were paralyzed in 2011, in the 2013 3.20 cyber attack happened and classified documents of Korea Hydro & Nuclear Power Co. Ltd were leaked on december in 2015. All of them were conducted by a foreign country. These attacks were planned for a long time compared to the script kids attacks and the techniques used were very complex and sophisticated. However, no successful solution has been implemented to defend an APT attacks(Advanced Persistent Threat Attacks) thus far. We will use big data analytics to analyze whether or not APT attacks has occurred. This research is based on the data collected through ISAC monitoring among 3 hierarchical Korean Defense System. First, we will introduce related research about big data analytics and machine learning. Then, we design two big data analytics models to detect an APT attacks. Lastly, we will present an effective response method to address a detected APT attacks.

This research is based on the data collected through ISAC monitoring among 3 hierarchical Korean defense system. First, we will introduce related research about big data analytics and machine learning. Then, we design two big data analytics models to detect an APT attack and evaluate the models' accuracy and other results. Lastly, we will present an effective response method to address a detected APT attack.

Cyber attacks are threats to national security. Today, cybersecurity threats have various types, the theft or spread of privacy and national secret, the realization of direct attacks to infrastructure and the hacktivism with political or social objectives. Furthermore, There are special situations in South Korea because of North Korea's threats. Thus, It is necessary to handle cybersecurity as a kind of national security problem. It is a time to identify problems of governance system in cybersecurity and to improve related Acts and subordinate statutes. There are several tasks for legal improvement for governance system in cybersecurity. They are improving legal bases for the roles of the relevant authorities in cybersecurity, consolidating national joint response to cyber accidents, establishing and vitalizing information sharing system, constructing foundation of cybersecurity through industry promotion and manpower development, and acquiring defensive tools by enhancement research an development. In order to address these challenges, it is necessary to pay much attention to enactment and to revision laws and to practice legislative procedure.

Since the 2003.1.25 Internet Crisis, the government has been looking at a number of options to strengthen national cyber-security/crisis management capability to guard against ever increasing threat of cyber-war and terror. Thus, the focus of this study was to explorer new ways of developing a comprehensive cyber-security/crisis management system, in particular by combining modern social-science analytic theories. As a result, although there has to be more in-depth researches into incorporating advanced techniques to generate more detailed and object-specific indexes and protocols, the use of 'event data system,' which has been widely utilized in many recent social science researches to assess a wide-range of socio-political risks and crises, could be adopted as a basis for a comprehensive nationwide cyber-risk management system.

본 연구는 인터넷 사용자의 증가와 사용 환경이 급성장하는 가운데 유해성(각종 사이버테러 등) 역시 증가하고 있다는 문제점과 대응을 분석하였다. 이러한 상황에서 각종 정보보호시스템이 개발되어 운용되고는 있으나 현재까지 역추적 기술에 대한 완벽한 대안을 제시하고 있지는 못하고 있다. 해킹이 시도된 후 이를 막기 위한 제품/서비스로 해킹 시도 자체를 방지하는 데는 한계를 가지고 있다. 따라서 적절한 실시간 역추적 기술의 도입을 통해 기존 네트워크 체계의 문제점을 해결하고 보안성을 극대화 할 수 있을 것이다. 본 연구에서는 실시간 역추적 기술의 동향과 적용 사례 분석을 통한 이해와 개념을 제시한다.
