Development of IT technology as well as arrival of information-oriented society raise the curtain of 'the era of Ubiquitous Computing', implying accessing computers beyond boundary of time and space. In this era, it is expected that IT paradigms and life-styles would be transformed immensely above the experiences of 20th century. However, improvement of technology summons a new risk of cyber terrorism which have not been in the past. Thus, it is urgent to prepare for the threats in the national level. This paper point out five major threats relating to 'the security in the era of Ubiquitous Computing'. : First, spread of threats in connection with BcN establishment, second, vulnerable information-security for wireless communication, third, leakage of private information, fourth, cyber terror and deterioration of security, fifth, security problems of Korea including the drain of military information and solutions in the views of organization, personnel, technology and budget, comparing with other countries.

The recent cyber attacks paralyzed several major banking services, broadcasters, and affected the services of a telecommunications provider. Media outlets classified the attack as cyber terror and named it an Advanced Persistant Threat. Although the attack significantly disrupted these services for at least one day, various components used in the attack were not new. Previous major cyber attacks towards targets in South Korea employed more advanced techniques thus causing greater damage. This paper studies the anatomy of the recent 2013.3.20 attack, studies the technical sophistication of the malware and attack vectors used compared with previous attacks.

Terrorism which became today's common phenomena over the world is one of the most serious threats the world confront. Although International society make and operate outstanding anti-terrorism system, terror would never end without solving fundamental problems. The main body of terrorism converts from nation to organization and from organization to cell, which makes it difficult for us to recognize the main body. Since the target of today's new terrorism is many and unspecified persons, terrorists will never hesitate to use mass destruction weapons such as nuclear, biological, chemical weapons, and also use cyber-technique or cyber-terrorism. So, effective counter-terrorism measures should be performed as follows. First, it must be better for international society should make long-time plan of solving fundamental problems of terrorism other than to operate directly on terror organization and its means. Second, preventive method should be made. The most effective method of eradicating terrorism is prevention. For this, it is necessary to remove environmental elements of terrorism and terrorist bases, and to stop inflow of money and mass destruction weapons to terrorists. Third, integrated anti-terror organization should be organized and operated for continuous counter-terrorism operations. Also international alliance for anti-terrorism should be maintained to share informations and measures. Fourth, concerned department in the government should prepare counter-terrorism plans in their own parts as follows and make efforts to integrate the plans. - Ministry of Government Administration and Home Affairs : conventional terror - Ministry of Health and Welfare : bio-terror - Ministry of Science and Technology : nuclear-terror Especially, they should convert their policy and operation from post-terror actions to pre-terror actions, designate terror as national disaster and organize integrated emergency response organization including civil, government, and military elements. In conclusion, pre-terror activities and remedy of fundamental causes is the best way to prevent terror. Also, strengthening of intelligence activities, international cooperations, and preventive and comprehensive counter-measures must not ignored.

연구와 군사 목적으로 발전한 인터넷은 현재 많은 기업들과 일반인들이 사용하는 현대 사회의 중요한 기반 시설로 자리잡게 되었으며, 아울러 인터넷이 사회에 끼치는 영향이 커짐에 따라 여러 가지 목적으로 자신의 접속 위치를 우회하여 숨기고 인터넷 보안 모델의 취약점을 공격하는 침입자가 증가하고 있다. 따라서, 침입에 사용되는 기술과 그에 대한 대응 기법 또한 보다 복잡하고 정교해 지고 있으나 근본적으로 악의적 침입을 근절하는 능동적인 대응은 미약한 현실이다. 본 논문에서는 인터넷 환경에서 여러 가지 우회 경로를 통해 접근한 침입자의 실제 접속 위치를 효율적으로 추적하기 위해 기존 역추적 연구의 유형과 문제점을 살펴보고 차세대 인터넷 환경에서 활용 가능한 역추적 기법의 모델을 제시한다. 따라서, 기존 역추적 기법의 현실적으로 적용이 어려운 구성과 침입자의 보안 설정에 따른 추적 제한 등의 문제점을 살펴보고 그 해결 방안이 되는 새로운 역추적 시스템의 모델을 제시한다. 그리고, 본 연구에서 제시하는 모델은 기존의 연결 경로를 거슬러 추적하는 기법과 달리 프록시 등 우회 경로를 통해 접근한 침입자에 대해 직접 연결되는 프로토콜을 자동 실행 되도록 구성하여 접근한 침입자의 위치를 파악하는 모델이나. 이 모델을 적용할 경우 실제 적용 가능한 구성과 효율적인 추적 특성을 가지게 되며 구성 비용의 손실 또한 줄일 수 있게 되는 장점을 가지게 된다.

사용자가 안전한 WiBro 서비스를 받기 위해서 사용자 단말과 ACR(Access Control Router) 간에 인증이 선행되어야 한다. 그렇지 않을 경우, 많은 공격 위험으로부터 노출될 수 있다. 따라서 한국정보통신기술협회(TTA)에서는 휴대인터넷(와이브로$^{TM}$) 서비스를 위한 상호 인증 절차 표준을 제정하였다. 이 표준 프로토콜은 PISIM(Portable Internet Subscriber Identity Module)을 이용하여 PE(Portable Equipment)와 ACR 간에 상호 인증을 수행한다. 그러나 표준은 인증에 필요한 메시지의 수가 대체적으로 많은 편이며 PISIM의 분실과 에러가 발생했을 경우에는 사용자는 무선인터넷 서비스를 사용할 수 없게 된다. 따라서 본 논문에서는 ACR과 PSS 간에 키 동의 프로토콜을 수행하여 PSS를 인증한다. 이때 PSS의 계산량을 지원하기 위한 PSD(Power Support Device)가 키 동의 프로토콜에 참여하게 된다. 이렇게 생성된 키는 ACR과 안전한 통신 세션을 맺고 있는 KAS(Key Authentication Server)에 PSS의 식별자와 키 정보를 암호화에서 저장한다. 끝으로 제안된 프로토콜의 안전성과 효율성을 분석한다.

The numerous definition of terrorism is viewed as the use of force or violence by individual or group that is directed toward civilian populations and intended to instill fear as a means of coercing individuals or groups to change their political or social positions. Recently, the paradigm of terror has been developed as new terrorism motivated by 9. 11 terror in 2001. In these contexts, this study analyzed the case study of recent counter-terrorism of international events and suggested the policy implications. This study is split into four chapters. Chapter I is the introduction part. Chapter II introduces the reader to new terrorism theory, and Chapter III deals with the case study of the international counter-terrorism policy around the world, Chapter IV deals with the policy implications of the case study. The greater the political, economical and social advantages opening large international ceremonies, the larger the probability of being targets for terrorists and criminals. As terrorism is one of the important issue, the security problems at international ceremonies in Korea, rising country as political essence in Asian-Pacific region, become very important. With experienced know-hows against terror and preparations for security, local and central governments must promote the private security companies filling up vacancies of police and official security system and develop international ceremonies, rising high valuable industries in 21st century, with diplomatic efforts. International major events is the largest event related events with politics, economy, culture, and such large-scale events should be a comprehensive counterplan in the light of safety check for the location of a hazard and safety check of facilities in and out, attendance on athlete and visitor and escort of VIPs.

In the mordern society, the reliance on the cyber domain and the cyber connectivity has been increasingly strengthened. Due to this phenomenon, the cyberterror against critical infrastructures and state organs might lead to fatal consequences. Lately, North Korea's cyberattacks against South Korea's national organizations and financial computer networks are becoming more and more intelligent and sophisticated. The cyberattacks against such critical infrastructures have caused enormous economic loss and social disorder. This paper is designed to examine comparatively the cyberterror related laws and organizations of the advanced countries such as U.S. and U.K. and to draw implications. Although those countries are under different institutional and cultural backgrounds with varying security envrionments, they are identically pursuing measures by establishing government-wide counterterror system for coordination and cooperation. They are also commonly focusing upon creating new organizations equipped with new system and upon enhancing intelligence performance and devising punishment regulations. Korea is lack of framework laws regulating cyber security, having only scattered individual laws. Since such legal base is far from efficient counterterror activities, it is necessary that the legal and policy response of the advanced countries should be closely studied for selective introduction. That will eventually lead to legislation of cyber security law. With such legislation on hand, it is subsequently required to strengthen crisis management for prevention of cyberterror and to create joint response team, cooperating with private organizations.
