정보화 시대의 도래와 함께 원자력발전소 등 사회 간접자본의 중요 시설에서 운영되는 각종 장치들 역시 디지털화되면서 기존에 존재하지 않았던 사이버 공격에 대한 위협이 현실화되고 있다. 이러한 중요 사회 간접자본 등의 운영에 위협을 가하는 행위는 사회적으로 경제적으로 매우 큰 재난을 발생시킬 수 있기 때문에 공격 발생 이전에 사전 방어 체계를 구축해야 하는데, 이때, 실질적으로 위협이 되는 취약점의 존재 여부를 사전 인지하는 것이 매우 중요하다. 이를 위하여 본 논문에서는 원자력발전소의 계측제어계통에서 운영되는 국산화된 디지털 장치에 대하여 관련 취약점을 확인하고 확인된 취약점의 실질적인 위험도를 장치의 운영환경 특징을 반영하여 도출하며, 주요 기기의 운영 규제지침의 준수 여부를 점검하는 도구의 개발 결과를 소개한다. 본 논문은 원자력발전소 상에서 운영되는 시스템을 주요 대상으로 작성되었다.
