초록

최근, 에너지, 정보통신, 방위산업, 정부, 금융 등 국가기반시설(national critical infrastructures)들에 대한 사이버 보안 위협이 급격히 증가하고 있으며 이에 대응하기 위해 미국을 비롯한 주요 국가에서는 감시제어 및 데이터 취득 시스템(SCADA: Supervisory Control and Data Acquisition)에 대한 사이버 보안에 많은 노력을 기울이고 있다. 특히, 주요 국가 기반시설은 다양한 실시간 분산 제어시스템 및 네트워크를 통해 사이버 세계(cyber world)와 물리적 세계(physical world)를 연계한다. 하지만 이 같은 역동성(dynamic), 확장성(scalability), 다양성(diversity)으로 특징지어질수 있는 실시간 분산 제어시스템간의 상호연결과 연동을 통해 구성되는 해당시설은 기존의 보안기술 적용을 통해 보안성향상을 기대할 수 없다. 따라서 본고에서는 실시간 분산 제어시스템과 다양한 네트워크로 구성되는 기반시설들을 대상으로 하는 여러 가지 보안 위협 및 특징을 소개하고 이에 대응하기 위한 전략 및 연구기술 동향을 간략히 서술한다.
