지식정보사회에서 발전된 네트워크 인프라를 바탕으로 전산망의 구조는 보안성을 확보한 다양한 형태의 망 구성을 구축하여 운영하고 있다. 국가·공공기관 전산망의 경우 각 기관별 특성과 연계 기관까지 고려한 기술적, 관리적 보안환경 구축이 필요하며, 이를 위해 기관별 특성에 따른 사이버 위협을 분류 및 위협 지도를 바탕으로 기술적·관리적 취약점 및 사이버 위협을 분석 등을 통한 사이버 훈련을 위한 기본 연구의 중요성이 대두되고 있다. 따라서 본 연구에서는 인터넷망과 국가정보통신망의 이원적 인프라 망을 기반으로 구축되어진 국가·공공기관 전산망의 내·외부 사이버 위협에 따른 유형별 분석을 사례 기반의 시나리오를 통해, 실질적인 사이버 위협 요소를 도출 및 분석하여 사이버보안 훈련 요소 도출용 사이버 위협 MAP을 제시하고자 한다.

An overall responding security-centered framework is necessary required for infringement accidents, failures, and cyber threats. On the other hand, the correspondence structures of existing administrative, technical, physical security have weakness in a system responding to complex attacks because each step is performed independently. This study will recognize all internal and external users as a potentially threatening element. To perform connectivity analysis regarding an action, an intelligent convergence security framework and road map is suggested. A suggested convergence security framework was constructed to be independent of an automatic framework, such as the conventional single solution for the priority defense system of APT of the latest attack type, which makes continuous reputational attacks to achieve its goals. This study suggested the next generation convergence security framework to have preemptive responses, possibly against an APT attack, consisting of the following five hierarchical layers: domain security, domain connection, action visibility, action control, and convergence correspondence. In the domain, the connection layer suggests a security instruction and direction in the domains of administrative, physical and technical security. The domain security layer has consistency of status information among the security domain. A visibility layer of an intelligent attack action consists of data gathering, comparison and decision cycle. The action control layer is a layer that controls the visibility action. Finally, the convergence corresponding layer suggests a corresponding system of before and after an APT attack. The administrative security domain had a security design based on organization, rule, process, and paper information. The physical security domain is designed to separate into a control layer and facility according to the threats of the control impossible and control possible. Each domain action executes visible and control steps, and is designed to have flexibility regarding security environmental changes. In this study, the framework to address an APT attack and load map will be used as an infrastructure corresponding to the next generation security.

This study analyzed President Park's speeches and the government's industry policy in the field of information security using cognitive map. The relationship analysis between policy tool variables and policy goal variables was employed to derive revitalization strategy of information security. This paper found that entrepreneurship revitalization has very strong causality with expansion of domestic market and global market. But, on the other hand, HR development has very weak causality with job creation and future growth driver because the labor market in the information security industry is poor and its transfer rate to other industry is very high. This study showed that this cognitive map could be characterized by a scarcity of feedback loops and a strong emphasis on the positive loops in the structure of virtuous circle. In this paper, we also constructed a comprehensive cognitive map on the policy vision of information security, showing that there are a risk of cyber threat, an opportunity of new fusion security market, information security reinforcing circle, global economic circle, and domestic market circle.

사이버전 훈련은 사이버전 역량 제고를 위한 핵심 수단이다. 일반적으로 사이버전 훈련은 시나리오에 의해 진행되며, 훈련의 질을 높여줄 수 있는 다양한 요소를 시나리오에 포함시킴으로써 훈련의 효과를 배가시킬 수 있다. 본 논문에서는 훈련 시나리오에 포함시킬 요소로 식별된 훈련 정보, 네트워크 맵, 트래픽 발생 정책, 위협/방어 행위를 소개하고, 이를 계층화하여 조합하는 방식으로 다양한 훈련 시나리오를 저작하는 방법을 제시한다. 그리고 각 시나리오 계층을 통합적으로 관리하기 위한 데이터베이스 설계를 제안한다. 계층적 훈련 시나리오 저작 방법은 기 저작된 계층들의 재사용을 통한 저작 편의성의 증대와, 계층 간의 다양한 조합을 바탕으로 훈련 시나리오를 확장시킬 수 있다는 장점을 가진다.
