It is expected that the technology of the fourth industrial revolution will increase the productivity and efficiency of the industrial world. Many countries are providing political and financial supports to make big advances in the technology. Especially, developed countries, such as USA, Germany and Japan, are trying to use the technology for manufacturing and finance industry, and to increase the opportunity of test-bed environment. However, many restrictions hinder adopting non-governmental technology in defense due to various limitations such as national security and protection of technology. In this study, we propose methods to adopt new and non-governmental technology in defense through by investigating internal and external policies related to technology and case studies. First, it is necessary to expand opportunities to let small and medium sized companies participate in defense R&D projects. Second, it is important to improve R&D systems for introducing new and non-governmental technology on the defense industry. Third, it is needed to increase test-bed environments for experimenting and evaluating new technologies in the defense industry. Thus, we expect that the proposed methods will help form strategies for small and medium sized companies, and analyze trends for introducing new technologies in the defense industry.

Around the middle of the ninth century the strict bone-rank system of Silla frustrated many people who had political ambition but lacked nobility. They had to seek other ways, including maritime trade. Such an undertaking reflected and also increased their economic and military power. Trade prospered with T'ang China and with Japan as well. The threat of piracy to Silla's thriving maritime trade caused to create a succession of garrisons at important coastal points. Chonghae Jin (Chonghae garrison) was regarded as the most important of these. It was established in 828 by Chang Pogo. Chonghae Jin was on Wando, an island just east of the southwestern tip of Korea and a key place at this time in the trade between China, Korea, and Japan. From this vantage point Chang Pogo became a merchant-prince with extensive holdings and commercial interests in China and with trade contacts with Japan. Although piracy was rampant in East Asia at that time, either the Chinese or Silla government was not able to control it due to inner political strife and lack of policing resources. Infuriated by the piracy and the government's inability to control it, Chang Pogo came back to Silla to fight against the pirates and to protect maritime trade. He persuaded the king of Silla and was permitted to control the private armed forces to sweep away the pirates. In 829 he was appointed Commissioner of Chonghae-Jin with the mission of curbing piracy in that region. Chang's forces were created to protect people from pirates, but also developed into traders among Silla Korea, T'ang China, and Japan in the 9th century. This was geographically possible because the Chonghae Garrison was situated at the midpoint of Korea, China, and Japan, and also because Chang's naval forces actually dominated the East Asia Sea while patrolling sea-lanes. Based on these advantages, Chang Pogo made a great fortune, which might be collected from a charge for protecting people from pirates and the trades with China and Japan. Chang's forces could be termed the first private security company in the Korean history, at least in terms of historical documents. Based on historical documents, the numbers of private soldiers might be estimated to exceed tens of thousands at least, since Chang's forces alone were recorded to be more than ten thousand. Because local powers and aristocratic elites were said to have thousands of armed forces respectively, the extent of private forces was assumed to be vast, although they were available only to the privileged class. In short, the domination of Chang's forces was attributable to the decline of central government and its losing control over local powers. In addition it was not possible without advanced technologies in shipbuilding and navigation.

군사 등의 특수 목적으로만 사용되었던 무인비행체 드론이 최근 상용 수준의 간결한 구조와 저가화가 가능해지면서 여러 제조업체를 통하여 민간분야의 다양한 응용에 활용 가능함을 증명하고 있다. 그러나 제조업체들 간의 시장 우위 선점을 위한 과열 경쟁으로 인하여 보안 안전성 검증 단계를 거치지 않은 드론과 이에 수반되는 애플리케이션이 시장에 바로 출시되면서 이들이 우리 사회를 향한 공격도구로 활용될 수 있다는 새로운 잠재적 위협이 우려되고 있다, 이와 관련하여 현재 드론과 애플리케이션과의 연결 및 데이터 통신 과정에서 완성도가 낮은 접근제어 기술이나 암호화되지 않은 통신방식을 비롯하여 드론 내부 소프트웨어의 코딩 상의 문제점 등에 의하여 다양한 취약점이 노출되고 있는 상태이다. 이러한 취약점들로 인하여 드론의 인증 해제 및 하이재킹을 통한 불법 영상촬영이나 개인정보의 유출 등을 비롯하여 특정 목표물을 향한 드론의 고의적 추락 등이 발생할 경우 재산 피해뿐만 아니라 인명 피해까지 발생할 수 있다. 특히, 현재의 드론 응용은 초기단계여서 향후 다양한 응용과 유관 기술들이 폭넓게 전개되어야 하는 시점에서 이러한 사고 가능성은 매우 심각하게 인식되어야 할 것이다. 더구나 제4차 산업혁명 시대의 드론은 비상시를 위한 다이나믹 모바일 게이트웨이 역할까지도 수행하여야 하는 환경에서 악의적인 행위는 전체 사회로 확산될 우려도 있으므로 미래 사회의 드론을 위한 안전문제는 매우 시급하고 중대하다고 할 수 있다. 이에 본 고에서는 현재까지 발표된 드론에 대한 다양한 보안위협을 조사하고 이러한 보안 위협을 요소별로 분류하여 정리하였다. 본 기고가 간단하게나마 정리한 내용을 통하여 다양한 보안위협에 대한 대응기술을 준비하기 위한 시발점이 되었으면 한다.

Blockchain technology has the potential to revolutionize trust models and business processes in a variety of industries. However, it is considered to be the initial stage of the system that pursues autonomy rather than efficiency, and it is necessary to monitor and inspect the distributed ledger technology from the price and introduction time as compared with the existing relational DB transaction technology. However, domestic and foreign private sectors have already been activated by applying block-chain technology in the national domain, and the block chain is devoid of doubt that it is an exaggerated technology, characterized by the invariance of the record, transparency, and autonomous execution of business rules. It has begun to be utilized in history, identity, certification and auditing in the financial industry as well as various industries. In this paper, we analyze the problems such as security weakness, insufficient regulatory environment, technical consensus and lack of common standard. In addition, the business sense and possibility of the block chain technology is expected to be the innovation of the industrial ecosystem by entering into the reality system from the concept through monitoring the actual introduction performance in the field of copyright, logistics, health care and environment.
