정보기술이 발전함에 따라 편리성이 향상되고 있지만, 사이버 공간에서의 보안 위협은 증가하고 있다. 최근에는 국가 기반시설과 같은 주요 인프라와 기관 및 기업을 목표로 하여 사이버 공격을 시도하고 있고, 해당 공격 방법도 지능적으로 발전하고 있다. 따라서 사이버 공간의 보안 위협에 대응하기 위해 국가적 차원에서 전략을 마련하고 있다. 특히 사이버 보안과 관련하여 미국은 사이버 공격에 대응하기 위해 각 기관의 연계성 및 협력을 위한 전략을 타 국가보다 앞서 준비하고 실행을 하고 있다. 따라서 본 고에서는, 국내 사이버 공격에 대한 보안 전략 수립을 위해 최근 사이버 공격이 이루어지는 유형과 사례를 분석하고, 이에 대처하는 미국 각 기관의 전략과 역할에 대해 분석한다.

The development of modern ICT technology constitutes cyber world by using infrastructure in country and society. There is no border in cyber world. Countries around the world are carrying out cyber attacks for their own benefit. A cyber killer strategy is needed to defend cyber attacks. In order to defend the cyber attack or to determine the responsibility of attack, it is important to grasp the attacker origin point. Strategic cyber kill chains are needed to strike against the attacker origin. In this paper, we study the analysis of attacker origin. And analyze the cyber kill chain for attacker origin point strike. Study the efficient and customized cyber kill chain strategy for attacking the origin point. The cyber kill chain strategy will be a practical strategy to replace the power of nuclear and missiles with asymmetric power.

In a study involving 52 large organizations in the savings institutions industry, the relationship between information systems technology(IT) structure and competitive strategy was investigated based on structural contingency theory. Two dimensions of IT structure and two types of competitive strategy were employed to test a contingency mood. It was found that enhanced congruence between IT structure and competitive strategy was associated with higher competitive advantage. The structural dimension significantly associated with the "defender" strategic stance was more centralized and more integrated application of IT, while the structural dimension significantly associated with "prospector〃 positioning was more decentralized and less integrated application of IT.lication of IT.

Recently various types of cyber attacks have occurred. The strategic goals & tactical means of these have evolved. Especially KHNP cyber attack was the type of hacktivism combined hack and psychological warfare. The cyber attackers have forecd the nation to participate in the cyber warfare and the government to make strategic decisions to the releases of confidential information and the threats of stopping KHNP. In this paper, we would like to study the effective strategic decision-making model utilizing the game theory and including an attack intelligence on open policy Decision framework.

사이버 공격으로부터 원자력 시설을 보호하기 위해 동원되는 갖가지 안전 대책을 다루고 있는 문건은 상당히 많다. 스파이 소설에 나오는 것 같은 사이버 보안상의 공격과 그 방어 전략에 대한 관련 기관들의 검토도 끊임없이 지속되고 있다. 그러나 이제는 원전사업체들도 발생이 가능한 모든 복합적인 위협은 물론 직접적인 사이버 공격을 고려해서 자체적인 대비책을 강구할 필요가 있다.

Cyber Threat Intelligence (CTI)는 성장하는 사이버 공격에 대응하는 새로운 보안체계 개념으로써 최근 많은 조직에서 보안성을 향상시키기 위해 도입하고 있다. 조직에서 CTI의 도입은 보안 조직간의 위협 정보와 그에 대응할 수 있는 방어 전략을 공유하여 다양한 선제공격을 방어하기 위해 필수적이다. 이에 따라 CTI 위협 정보를 공유하는 조직이 점차 늘어나고 있으며 정보의 양은 점차 많아지고 있다. 하지만 정보를 공유받는 대부분의 조직이 공격자가 악의적으로 잘못된 위협 정보를 수집한 경우 또 다른 사이버 공격으로 이어질 수 있다. 본 논문에서는 CTI 정보 공유에서 사이버 위협 대응 조치 전략을 조직에 적용하기 전에 가상의 네트워크 아키텍처에서 적용시킨 후 평가 및 검증을 통해 공격을 목적으로 한 악의적인 정보가 적용되지 않도록 사전에 방어한다.

This paper attempts to examine the changes in China's naval strategy and to analyze the goal, range, and method of each strategy during the Xi Jinping's era. Since the founding of New China, the People's Liberation of Army Navy(PLAN) has made four changes in the naval strategy. Under Xi Jinping's administration, China's naval strategy is far seas operation combined with near seas active defense. Now, China's naval strateg y is shifting from a defensive to an aggressive one, increasing the proportion of offensive weapon systems and the number of state-of-the-art warships, and the scope of the naval strategy has been specified in the second island chain including the Indian Ocean. With the changes of naval strategy, the PLAN will set a new strategic goal to secure maritime dominance and implement an assertive strategy to actively respond to the intervention and intrusion of external forces. Moreover, the PLAN will also improve its sea-based deterrence force and the maneuver force to block other countries in the long-distance maritime conflict zones. The operation method of China's future naval strateg y will gradually shift from 'interdiction' to 'rapid-response.'

There has been so many research activities about robot soccer system in the many research fields, for example, intelligent control, communication, computer technology, sensor technology, image processing, mechatronics. Especially researchers research strategy for attacking in the field of strategy, and develop intelligent strategy. Then, soccer robots cannot defense completely and efficiently by using simple defense strategy. Therefore, intention extraction of attacker is needed for efficient defense. In this thesis, intention extractor of soccer robots is designed and developed based on FMMNN(Fuzzy Min-Max Neural networks ). First, intention for soccer robot system is defined, and intention extraction for soccer robot system is explained.. Next, FMMNN based intention extractor for soccer robot system is determined. FMMNN is one of the pattern classification method and have several advantages: on-line adaptation, short training time, soft decision. Therefore, FMMNN is suitable for soccer robot system having dynamic environment. Observer extracts attack intention of opponents by using this intention exactor, and this intention extractor is also used for analyzing strategy of opponent team. The capability of developed intention extractor is verified by simulation of 3 vs. 3 robot succor simulator. It was confirmed that the rates of intention extraction each experiment increase.

Situational Crisis communication theory (SCCT), one of the major crisis communication theories, suggests that crisis managers have to choose the most effective crisis response strategy in accordance to the crisis type. Therefore, this study analyzed whether the crisis response strategies of Korea companies are different according to the types of crisis. According to the result of analysis on survey to PR managers, the crisis response strategies are different according to the types of crisis. And the role and function of PR team are different according to the types of crisis, too. This conclusion can contribute to devising SCCT theory and to develop a more Korea relevant theory.
