It becomes common to use computers to control electronic devices and security facilities in newly constructed buildings and house. There are many home application devices in the market which can be controlled by computers. But they are expensive and managed by specialized companies. This paper is focused on personal computers which are available in most homes and can be used to control home electronic appliances and home security facilities. We implemented a home automation server based on Linux. The standard parallel port of personal computer is used to connect sensors and actuators. Therefore, the cost of the server is very low. Moreover, the server is connected to Internet and anywhere we can control and monitor the home security facilities and home automation systems.

Industrial control systems in nuclear facilities are facing increasing cyber threats due to the widespread use of information and communication equipment. To implement cyber security programs effectively through the RG 5.71, it is necessary to quantitatively assess cyber risks. However, this can be challenging due to limited historical data on threats and customized Critical Digital Assets (CDAs) in nuclear facilities. Previous works have focused on identifying data flows, the assets where the data is stored and processed, which means that the methods are heavily biased towards information security concerns. Additionally, in nuclear facilities, cyber threats need to be analyzed from a safety perspective. In this study, we use the system theoretic process analysis to identify system-level threat scenarios that could violate safety constraints. Instead of quantifying the likelihood of exploiting vulnerabilities, we quantify Security Control Measures (SCMs) against the identified threat scenarios. We classify the system and CDAs into four consequence-based classes, as presented in NEI 13-10, to analyze the adversary impact on CDAs. This allows for the ranking of identified threat scenarios according to the quantified SCMs. The proposed framework enables stakeholders to more effectively and accurately rank cyber risks, as well as establish security and response strategies.

산업제어시스템(ICS)은 분산된 다양한 자산을 측정, 감시, 제어하는 시스템으로 에너지, 화학, 교통, 수처리, 제조 공장 등의 산업 시설 및 국가기반시설에서 사용된다. 산업제어시스템의 특성상 보안위협에 노출되면 오동작, 중단 등으로 인해 막대한 인명, 자산 피해 등이 발생할 수 있어 산업제어시스템의 보안위협을 예방하고 최소화하기 위한 연구가 필요하다. 기존의 산업제어시스템의 경우 보안위협을 고려하여 무선통신기기의 사용을 제한하였으나 최근에는 유지보수의 용이성 및 비용의 장점으로 인해 산업용 무선통신기기 도입이 점차 증가하고 있다. 이에 본 논문에서는 WirelessHART와 ISA100.11a를 지원하는 산업용 무선통신기기의 보안위협을 분석하고, 분석 결과를 기반으로 산업용 무선통신기기의 도입 및 운영에 필요한 보안요구사항을 제시하였다. 본 연구에서 제시한 보안요구사항을 활용하여 국가기반시설을 포함한 다양한 산업분야의 산업용 무선통신환경 구축 시 보안위협을 완화할 수 있을 것으로 기대한다.

A questionary survey was conducted to investigate citizen's attitude to treatment facilities of municipal solid waste in Miryang during 8. June of 1998 and 22 June of 1988. Collection effiencies was 86.7%, as 260 individuals of the 300 individuals. The survey showed that 43.0% of answers recognized seriousness of problem of the waste treatment and 33.1% of respondents concerned about recycle of organic waste. 40.8% of total answers said that they most hated landfill site among waste treatment facilities, and most citizens wanted as much distant as possible from waste treatment facilities. It was investigated that the greater part of respondents wanted the greatest compensation. About 58% of respondents was opposed to complete waste treatment facilities. 36.2$ among answers wanted establishment of waste treatment facilities in an industrial complex or an industrial area. The majority of respondents was willing to increase recycle rate and recognized seriousness of landfill site security. The majority of citizens do not trust environmental administration of Miryang City and they think that democracy and open of administration need for overcome MINBY.

산업 현장에서 일반 컴퓨터와 윈도우 운영체계를 사용하여 생산 시스템을 제어 하게 되면서, 산업 시설에 대한 사이버 보안 위협이 심각한 문제로 대두 되고 있다. 네트워크와 연결된 산업 제어 시스템은 우리가 일상적으로 사용하는 PC나 기업의 정보 시스템에서 문제시 되던 악성코드의 공격에 노출되었다. 특히 컴퓨터 웜인 스턱스넷은 가스 수송관이나 발전소 같은 특정 산업 제어 시스템을 표적으로 하며, 이론상 물리적 타격도 가능하다. 본 논문에서는 산업 제어 시스템 구성 요소와 SCADA의 사이버 보안 위협을 살펴본 후, SCADA 보안 취약점을 조기에 파악하고 평가하여 가능한 사이버 공격을 사전에 대처할 수 있는 위험 분석 방법으로 공격 트리 분석을 고찰한다.

SCADA (Supervisory Control and Data Acquisition) system has been used fur remote measurement and control on the critical infrastructures as well as modem industrial facilities. As cyber attacks increase on communication networks. SCADA network has been also exposed to cyber security problems. Especially, SCADA systems of energy industry such as electric power, gas and oil are vulnerable to targeted cyber attack and terrorism. Recently, many research efforts to solve the problems have made progress on SCADA network security. In this paper, we introduce recent security issue of SCADA network and propose the application of encryption method to Korea SCADA network.

최근 국가 기반시설에 대한 사이버 공격이 지속해서 발생하고 있다. 이에 따라 ICS-CERT 취약점이 작년보다 두 배 이상이 증가하는 등 원자력 시설 등의 산업제어시스템에 대한 취약점이 날로 증가하고 있다. 대부분의 제어시스템 운영자는 미국의 ICS-CERT에서 제공하는 산업제어시스템 취약점 정보원을 바탕으로 취약점 대응 방안을 수립한다. 그러나 ICS-CERT는 연관된 모든 취약점 정보를 포함하지 않으며, 국내 제조사 제품에 대한 취약점을 제공하지 않아 이를 국내 제어시스템 보안에 적용하기 어렵다. 따라서 본 연구에서는 CVE, CWE, ICS-CERT, CPE 등의 공개된 취약점 관련 정보를 활용하여 제어시스템의 자산에 존재 가능한 취약점을 발견하고 향후 발생 가능한 취약점을 예측할 수 있는 방안을 제안하며, 이를 국내 주요 제어시스템 정보에 적용해보았다.

The airport processes are restricted by some limits of performance objects as size of airport, ability of human resources, capacity of facilities and operational rules. These limitations make passenger handling difficult when passenger numbers increase. In order to solve this problem, we modeled the airport process and analyzed departure passenger arrival, scheduled security manpower under specific customer service level maintenance with mixed integer programming and validate the efficiency with simulation with adapting smart airport framework. We concluded that the airport management with information techniques can reduce waiting time within security and immigration process.

As the interest in achieving an intelligent society grows with the fourth industrial revolution's development, information and communications technologies technologies like artificial intelligence (AI), Internet of Things, virtual reality, information security, and blockchain technology are being actively employed in different fields for achieving an intelligent society. With these modifications, the information security paradigm in industrial and public institutions, like personal sensitive data, is quickly changing, and it is exposed to different cyber threats and breaches. Furthermore, as the number of cyber threats and breaches grows, so does the need for rapid detection and response. This demand can be satisfied by establishing cyber training programs and fostering experts that can improve cyber security abilities. In this study, we explored the domestic and international technology trends in cyber security education and training facilities for developing experts in information security. Additionally, the AI technology application in the cyber training ground, which can be established to respond to and deter cyber threats that are becoming more intelligent, was examined.
