초록
기술의 진화와 함께, 사이버 물리 시스템(Cyber Physical System)은 향상되고 있고 이에 따라 새로운 유형의 사이버 공격도 발견되고 있다. 사이버 공격에는 여러 가지 형태가 있으며 모든 사이버 공격은 대상 시스템을 조작하기 위해 이루어진다. 사이버 물리시스템 중 대표적인 시스템이 사이버 물리 전력 시스템, 즉 스마트 그리드이다. 스마트 그리드는 신뢰할 수 있고 안전하며 효율적인에너지 전송 및 분배를 제공하는 새로운 유형의 전력망이다. 본 논문에서는 스마트 그리드의 상태 추정과 에너지 분배를 타깃으로하는 허위 데이터 주입 공격(False Data Injection Attack)으로 잘 알려진 특정 유형의 사이버 공격 구성 방법과 이러한 공격의방어를 위한 보호 전략과 탐지를 위한 동적 모니터링 기법을 소개한다.
Abstract
With the evolution of technology, cyber physical systems (CPSs) are being upgraded, and new types of cyberattacks are being discovered accordingly. There are many forms of cyber attack, and all cyber attacks are made tomanipulate the target systems. A representative system among cyber physical systems is a cyber physical powersystem (CPPS), that is, a smart grid. Smart grid is a new type of power system that provides reliable, safe, andefficient energy transmission and distribution. In this paper, specific types of cyber attacks well known as falsedata injection attacks targeting state estimation and energy distribution of smart grid, and protection strategies fordefense of these attacks and dynamic monitoring for detection are described.
