Abstract

사이버 물리 시스템(CPS, Cyber-Physical Systems)은 높은 신뢰성, 실시간성, 자동제어 특성이 요구되는 기반시설 제조 및 생산, 교통 등 산업분야에서 널리 쓰이고 있다. 센서와 액츄에이터 등의 현장장치를 네트워크 기반으로 일정한 상태를 유지하도록 제어를 담당하는 산업제어시스템이 그 예이다. 하지만, CPS는 네트워크 기반 상호 연결이 중가함에 따라 각종 사이버 공격이 급증하고 있는 추세이다. 이에 따라, CPS 보안 기술 연구의 필요성이 대두되었고, CPS 보안 기술 연구개발에 반드시 필요한 기반 환경으로써, 사이버영영과 물리영역을 포함하는 CPS 테스트베드 기술 연구가 활발히 진행 중에 있다. 본 논문에서는 CPS 관련 테스트베드 기술 동향 분석에 앞서 표준 및 지침에 명시된 CPS 구조에 대해 분석하고, 기존에 연구된 CPS 테스트베드 기술을 CPS의 계층적 구조를 기반으로 구성요소 및 구성방법을 비교 분석한다. 또한, CPS 테스트베드와 연계한 제어프로토콜 지원 현황과 사이버공격 시나리오 특징을 분석한다.
