The industrial foundation of the inside and outside of a country has brought significant damages due to attacks from hackers. Especially, if the national primary core infrastructures(like electric power, dam, railroad, atomic energy, etc.) has been significantly damaged, it can be directly linked not only to economic problems but also to people's lives. These national primary core infrastructures usually constitute SCADA system using Modbus RS486 communication. Because of this characteristic, SCADA system has RTU master and slave linked to RJ11 cables to directly pass commands. RJ11 is possible in data spoofing using physical connection because the transmission range of RJ11 has a wide bandwidth(almost 1km). Hence, this paper designed an idle-time measurement system for SCADA system for emerging security improvement in the national primary core infrastructures.

In a hyper-connected society, electric power infrastructures and information and communication infrastructures are the core of critical national infrastructures. However, electric power infrastructure is very deadly to high-frequency nuclear electromagnetic pulse (HEMP) threats recently issued by North Korea, so the resilience through rapid recovery after attack is directly related to the survivability of our country. Therefore, electric power infrastructure should take precedence over any other key infrastructure, with preemptive protection measures and fast recovery plans. In this paper, the characteristics of the HEMP threats was examined, and the risks and effective major protection measures of the electric power infrastructures are discussed. In the future, it is expected that it will be able to help establish the direction of enactment and revision of legal schems related to the 'high power EMP infringement prevention' for Korea's electric power infrastructures.

미국의 방위 산업은 주 계약업체, 하청계약업체로 구성되는데, 주 계약업체는 주요체계 또는 완제품을 제조, 조립하며 하청계약 업체는 주요체계를 구성하는 종속체계와 구성품을 제조합니다. 주 계약업체가 부품을 해외로부터 확보하게 되면 미국내 하청계약 업체는 시장을 잃게 됩니다. 국방부나 미국 의회가 어떤 프로그램을 취소함으로써 생산시설의 폐쇄를 초래하는 주요한 사항은 산업기반에 대한 구조상의 영향을 먼저 고려해야 하며 국가안보이익을 위해 주 계약업체의 능력을 약화 또는 무력화 시켜서는 안될 것입니다

This study was to analyze data of climate change impacts on social infrastructure using text-mining methodology, and to visualize the spatial information by integrating those with regional data layers. First of all, the study identified that the following social infrastructure; power, oil and resource management, transport and urban, environment, and water supply infrastructures, were affected by five kinds of climate factors (heat wave, cold wave, heavy rain, heavy snow, strong wind). Climate change impacts on social infrastructure were then analyzed and visualized by regions. The analysis resulted that transport and urban infrastructures among all kinds of infrastructure were highly impacted by climate change, and the most severe factors of the climate impacts on social infrastructure were heavy rain and heavy snow. In addition, it found out that social infrastructure located in Seoul and Gangwon-do region were relatively largely affected by climate change. This study has significance that atypical data in media was used to analyze climate change impacts on social infrastructure and the results were translated into spatial information data to analyze and visualize the climate change impacts by regions.

Most national critical key infrastructure, such like electricity, nuclear power plant, and petroleum is run on SCADA (Supervisory Control And Data Acquisition) system as the closed network type. These systems have treated the open protocols like TCP/IP, and the commercial operating system, which due to gradually increasing dependence on IT(Information Technology) is a trend. Recently, concerns have been raised about the possibility of these facilities being attacked by cyber terrorists, hacking, or viruses. In this paper, the method to minimize threats and vulnerabilities is proposed, with the virtual honeynet system architecture and the attack detection algorithm, which can detect the unknown attack patterns of Zero-Day Attack are reviewed.

주요 국가기반시설에 도입되어 운영 중인 산업제어시스템은 4차 산업혁명에 따른 디지털 전환으로 지능화됨에 따라 IT환경의 보안위협이 OT환경으로 상속되면서 제어시스템 보안위협 및 공격 양상도 복잡해지고 있다. 실제로 에너지분야 기반시설을 대상으로 한 Stuxnet, Conficker, BlackEnergy3 등 제어시스템 사이버 위협 및 사고 사례가 지속적으로 보고되고 있으나, 제어시스템을 대상으로 하는 사이버공격 대응을 위한 보안가시성 확보는 제대로 이루어지지 않고 있으며, 이를 위해서는 기존 IT 환경과는 다른 제어시스템의 특성이 반영된 보안 모니터링이 요구된다. 본 논문에서는 제어시스템 보안위협 지식 데이터베이스인 MITRE ATT&CK 프레임워크를 기반으로 제어시스템에 적합한 보안 모니터링을 수행하기 위한 요소들을 식별하고 방안을 제시한다.

Contrary to past critical infrastructure network, current critical infrastructure network is adopting IoT devices and efficient management system using the external networks. Using this system, productivity and management efficiency could be enhanced compared to past critical infrastructure network. But cybersecurity issue could be occurred at external network connection, so cybersecurity guideline is necessary. However, critical infrastructure organizations tend to use the cybersecurity guideline issued by government because it is hard to develop cybersecurity guideline on their own. But the government's cybersecurity guideline isn't suitable for the critical infrastructure network because it doesn't include critical infrastructure's specific characteristics. Therefor, we suggested the development method of cybersecurity guideline for the critical infrastructure network based on analysing cybersecurity guideline standards and critical infrastructure networks.

The current Development Impact Fee (DIF) Zoning Law allows Korean localities to designate the DIF Zone for the areas where there have been up-zoning in land-uses due to any minute additions and/or amendments in the existing clauses or provisions in the National Territory Planning Law as well as all other laws related to urban and regional planning. In reality, however, it is almost impossible to trace the sporadic and infinitesimal changes that might occur in every corner of the statutory clauses of a great number of planning related laws. This study, in an effort to overcome such practical difficulties, tries to chase the time-series zoning alterations in especially the consecutive land-use information layers of the Korea Land Information System (KLIS) as comparable analogues of the outcomes of the amendments in various planning laws. A study locality is chosen among the entire localities in the Capital Region based on the selection criteria dictated by the DIF Zoning Law such as the population- and building permit increase rate. It has been verified that the methodology suggested herein is practically applicable and successfully capable of extracting a number of DIF zones with considerable areal sizes, which could not have otherwise been possible. The consequences of this study, in this context, are expected to contribute to prevent the uncontrolled developments as the DIF Zoning Law itself was originally intended to achieve.

국내 주요 인삼재배 산지 기반을 가진 전북 진안지역의 인삼 홍삼산업은, 재배농가 895호, 재배면적 402ha, 생산량 1,628톤, 홍삼가공업체 80개소, 판매업소 50개소로 지역경제의 25% 이상을 차지한다. 그러나 재배농가의 계열화 미흡(22%), 산지수집상(포전매매)에 의한 인근 유사 도매시장으로 재배물량과 부가가치 유출(78%), 가공시설의 노후화, 가공업체의 영세성(매출규모 연평균 2억11백만원)과 함께 중국, 캐나다, 미국 등의 국제 가격경쟁과 국내의 대기업 및 인삼산업 주요지역과의 경쟁이라는 상황에 직면하고 있다. 이러한 상황을 극복하고 지역특화명품산업으로 발전할 수 있는 방안으로, 인삼재배산지로서 원료공급지를 기반으로 하는 재배, 유통, 가공, 품질관리, 시설분야에 이르는 발전방안을 연구하였다. 산업원료 확보를 위해서는 인삼계열화 확대를 통해 원물 확보력을 강화하여야 한다. 재배분야의 경우에는 친환경재배 확대와 GAP 확대를 통해 원물의 품질경쟁력 뿐만 아니라 시장수요에 따른 브랜드마케팅 요인으로 특성화해야 한다. 유통분야는 계열화 확대를 통한 원물확보라는 산업경쟁력을 바탕으로 원료중심의 수취, 매취, 보관, 가공, 대형거래, 도소매 등 유통활성화와 유통규격포장 및 선별등급표준화를 통한 유통표준화를 추진하여야 한다. 가공의 경우, 원료홍삼 공급기능을 중심으로 가공산업을 선택 육성해야한다. 품질관리는 원물중심관리(성분, 잔류농약, 식품위생), 유통중심관리(연근, 등급), 경작중심관리(재배지, 재배자, 경작), 프로세스중심관리(재배 유통 가공 판매정보)로 구체화해야한다. 시설분야는 유통시설(대규모 집하시설, 보관시설 등 종합유통처리시설)과 가공시설(가공설비현대화, 가공공장 공인규격화;ISO, GMP, HACCP)의 지속적인 시설개선과 현대화를 추진하여야 한다.
