해외 기술 유출 사고로 인하여 한국 경제에 약 수조원의 피해가 발생하였다. 기업의 기술 유출과 사고 책임 소재를 증명하기 위한 e-Discovery시스템과 기업CERT/CC에 연구가 필요하다. 본 논문에서는 e-Discovery의 개념과 관련법안 및 권고안, 포렌식 수사절차에 대해 연구하고, 국내 e-Discovery 사고 사례와 해외 e-Discovery 사고 사례를 연구한다. e-Discovery가 도입되면 기업 CERT/CC에서 필요한 e-Discovery 시스템을 설계한다. e-Discovery 시스템의 접근과 인증을 위한 사용자인증과 기기 인증에 대한 기술과 암호화 기술을 연구한다. 본 논문 연구를 통하여 e-Discovery 제도의 도입과 포렌식 기술 발전에 기초자료로 활용될 것이다.

Cyber attacks expose sensitive information and cause fatal damage in both the public and the private sectors. Therefore, MKE (Ministry of Knowledge Economy) Cyber Security Center was founded on July 25, 2008, to perform three major roles. First, it detects and analyzes cyber attacks for the both sectors. Second, its ISAC (Information Sharing & Analysis Center) service analyzes and evaluates the vulnerability of the communication and network infrastructure to security threats, including control systems. Third, it provides CERT/CC (Computer Emergency Response Team Coordination Center) service to prevent and to respond to computer security incidents. This study focuses on the MKE Cyber Security Center's service analysis, which is playing an increasingly larger role in the both sectors. Based on this analysis, after grasping the response services activity and pointing out the problems, this study suggests improvements to the MKE Cyber Security Center.

Broadband Convergence Network(BcN) is a critical infrastructure to provide wired-and-wireless high-quality multimedia services by converging communication and broadcasting systems, However, there exist possible danger to spread the damage of an intrusion incident within an individual network to the whole network due to the convergence and newly generated threats according to the advent of various services roaming vertically and horizontally. In order to cope with these new threats, we need to analyze the vulnerabilities of BcN in a system architecture aspect and classify them in a systematic way and to make the results to be utilized in preparing proper countermeasures, In this paper, we propose a new classification of vulnerabilities which has been extended from the ITU-T recommendation X.805, which defines the security related architectural elements. This new classification includes system elements to be protected for each service, possible attack strategies, resulting damage and its criticalness, and effective countermeasures. The new classification method is compared with the existing methods of CVE(Common Vulnerabilities and Exposures) and CERT/CC(Computer Emergency Response Team/Coordination Center), and the result of an application to one of typical services, VoIP(Voice over IP) and the development of vulnerability database and its management software tool are presented in the paper. The consequence of the research presented in the paper is expected to contribute to the integration of security knowledge and to the identification of newly required security techniques.
