- W1970787687 abstract "공격자는 시스템에 침입하기 위해 시스템 취약점을 수집한 후, 여러 공격 방법을 통해 루트권한을 획득하여 시스템 정보를 유출 및 변조하며 더 나아가선느 시스템을 파괴한다. 이러한 공격에 대응하기 위해 침입 탐지 및 차단을 위한 보안 시스템들이 많이 개발디어 왔지만, 최근 공격자들은 보안 시스템들을 우회하여 시스템에 침입하기 때문에 많은 문제가 되고 있다. 본 논문에서는 루트권한을 획득한 공격자의 불법행위를 막기 위한 보안커널모듈을 제안한다. 보안커널모듈은 추가적인 패스워드를 통해 시스템의 관리자 인증을 강화하여, 공격자가 중요 파일을 변조하고 루트킷을 설치하는 행위를 막는다. 또한 공격자의 불법 행위에 대한 경고메일을 관리자에게 실시간으로 보내서, 관리자가 메일에 포함된 정보를 통해 새로운 보안 정책을 수립하도록 한다. Attackers collect vulnerabilities of a target computer system to intrude into it. And using several attack methods, they acquire root privilege. They steal and alter information in the computer system, or destroy the computer sysem. So far many intrusion detection systems and firewallshave been developed, but recently attackers go round these systems and intrude into a computer system . In this paper, we propose security kernel module to prevent attackers having acquired root privilege from doing illegal behaviors. It enhances administrator authentication with additional password, so prevents attackers from doing illegal behaviors such as modification of important files and installation of rootkits. It sends warning mail about sttacker's illegal behaviors to administrators by real time. So using information in the mail, they can estabilish new security policies." @default.
