The purpose of this study was to keep the Security Control Center, which operates under a shift system, uninterrupted during the COVID-19 virus epidemic. Security facilities responding to cybersecurity threats are essential security facilities that must be operated 24 hours a day, 365 days a day in real time, and are critical to security operations and management. If security facilities such as infectious disease epidemic, system failure, and physical impact are closed or affected, they cannot respond to real-time cyberattacks and can be fatal to security issues. Recently, there have been cases in which security system facilities cannot be operated, such as the closure of facilities due to the COVID-19 virus epidemic and the availability of security systems due to the rainy season, and other cases need to be prepared. In this paper, we propose a plan to configure a security system facility as a multiplexing facility and operate it as an alternative in the event of a closed situation.

물리적 단방향 자료전달 시스템은 산업제어시스템에 적용하여 보안등급이 높은 안전영역에서 보안등급이 낮은 비안전영역으로의 데이터 전송을 물리적으로 한방향으로만 전달하는 보안 시스템으로, 최근 사이버테러에 대한 사회적, 경제적 피해가 날로 증가함에 따라 다양한 산업제어시스템에서 단방향 자료전달 시스템에 대한 기술 개발 및 적용 요구가 증가하므로 본 연구에서는 단방향 통신 기술의 현 주소를 짚어보고 앞으로의 발전 방향과 저변 확대를 위한 방안을 제안한다.

In the midst of the rising need for Industrial Security experts, the development of National Competency Standards(NCS) with regards to industrial security is a very important and urgent task. The NCS standardizes university-level academic curriculum and qualification systems and connects them with the industry's needs. This study has extracted, classified and analyzed security-related jobs and tasks requiring security expertise that is required within NCS. Through this study, many tasks have been confirmed to require security competencies that are different from those in IT-security, physical security that already exist as a NCS tasks. It is expected that the industry's needs of industrial security expertise will be reflected in future NCS development, which will be used as basic data for systematizing industrial security jobs and competency.

기업 네트워크 환경 및 인터넷 상에서 발생할 수 있는 보안상의 취약점들은 악의를 가진 내외부의 공격자들에게 악용될 가능성이 있다. 이러한 상황은 기업으로 하여금 정보 자산의 유출 및 파괴 등의 물리적인 피해와 더불어 복구를 위한 인력 및 시간의 소요 등 금전적인 손해를 야기시킨다. 이에 정확한 네트워크 보안 위험을 분석하여 이러한 피해의 가능성을 사전에 파악하고, 예방할 수 있는 방안을 마련하여 최대한의 보안성을 확보하여야 한다. 본 고는 이를 해결하기 위한 네트워크의 보안 수준을 측정하고 분석할 수 있는 방법론을 살펴보고, 적절한 평가 절차 및 평가 수행 방법, 점검 항목을 해외이 대표사례와 국내 업체의 위험 분석 방법론 관하여 살펴본다.

충분한 보안 메카니즘과 보안 통신 능력이 없는 지능망에서는 우연이든 고의적이든 민감한 정보에 대한 적법하지 못한 노출이나 변경이 가능성이 더 높게 존재한다. 암호화 및 복호화 알고리즘과 같은 보안 메카니즘이 존재한다는 가정하에서 이 논문은 현재의 지능망에 보안 통신 능력을 추가하기 위한 포괄적인 프레임웍을 제안하다. 이를 위해, 서비스평면(SvP: Service plane), 총괄기능평면(GFP: Global Functional Plane), 분산기능평면(DFP: Distributed Functional Plane) 및 물리평면(Physical Plane)으로 구성되는 현재의 지능망개념모델을 기본으로 의 각 평면에서 추가되어야 할 보안 통신 능력을 제시한다.

Although three types of the information security measures (technical, physical and managerial ones) are all together critical to maintaining information security in the organizations and should be implemented at the same time, this study aims at providing theoretical basis of establishing and implementing effective managerial security measures. The rationale behind this research objective is that it is very important to effectively perform the managerial security measures to achieve the target performance level of the technical and the physical security measures because main agents of practicing the information security measures in the organizations are staff members even though the technical and the physical ones are well constructed and implemented. In particular, this study intends to develop and propose the theoretical model applicable to providing the way of improving organizational members' intention to use information security technologies since the very intention to use them is essential to effectively establishing and promoting managerial security measures. In order to achieve the objective of this study, the factors critical to influencing upon the intention to use information security technologies are derived through systematically reviewing related theories and previous studies, and then the research model and hypotheses are proposed by logically reasoning the casual relationship among the these factors. Also, the empirical analyses are performed by conducting the survey of the organization members of domestic large companies and analyzing the structural equation model by PLS (Partial Least Squares) method. The significant results of this study can contribute to expanding the research area of managerial information security and can be applied to suggesting the practical guidelines for effectively establishing and implementing the managerial security measures in various organizations.

JPMP SID Tag is the security senor tag to provides physical information protective function using sensor module, has impossible feature to copy and fake the data which is stored in the tag. So data which is stored in the JPMP SID Tag has authenticity, integrity, originality. Therefore JPMP SID Tag could be applied in the place where the security of data is demanded. This paper propose the system using the JPMP SID Tag to acquire and protect digital evidence where cause investigation of accident is necessary. Also, proposed systems is complement of software security with composition secondary control logic for JPMP SID tag access control.

Unlike a general IT environment, an industrial control system is an environment where stability and continuity are more important than security. In the event of a security accident in the industrial control system, physical motion can be controlled, so physical damage can occur and physical damage can even result in personal injury. Cyber attacks on industrial control systems are not simply cyber damage, but terrorism. However, the security of industrial control systems has not been strengthened yet, and many vulnerabilities are actually occurring. This paper shows that the PLC can be remotely controlled by analyzing the connection process and packets for the PLC protocol used in the industrial control system and bypassing the security mechanism existing in the protocol. Through this, we intend to raise the security awareness of the industrial control system.
