최근 인터넷 환경이 널리 퍼지면서 인터넷 서버들의 보안위협은 갈수록 증가하고 있다. 이러한 인터넷 서버의 보안 사고를 예방하기 위하여 기관들은 정보보호 솔루션인 방화벽, 침입탐지 시스템, 바이러스 백신, 보안운영체제 등을 도입하였으나 개별적인 보안 솔루션을 적용함으로써 관리 효율성이 떨어지고 보안 사고 위험은 증가하고 있다. 그래서 현재는 개별 보안 솔루션을 통합관리하는 ESM 을 도입하고 있다. 차세대인터넷 서버도 인터넷에 연결되어 있어서 해킹으로부터 자유로울 수 없기 때문에 차세대 인터넷 서버에 적합한 ESM 이 필요하다. 우리는 공개 소프트웨어 보안 도구를 조합하여 응용 프로세스 레벨에서 가볍고 기본 보안 기능을 충실히 갖춘 ESM 을 설계하였다. 본 논문에서는 그 ESM 의 설계 내용을 중심으로 자세히 소개하고, 현재까지 구현된 결과도 간략히 소개한다.
