EC2 Triage를 사용한 격리
격리 기능과 더불어 인시던트 중 AWS 보안 인시던트 대응 엔지니어가 실행 중인 인스턴스를 조사할 수 있는 기능이 모두 필요한 경우 이 템플릿을 사용합니다.
이 템플릿은 격리 전용 템플릿에 포함된 모든 항목을 생성하고 AWSSecurityIncidentResponseInvestigationPolicy을 AWSSecurityIncidentResponseContainment 역할에 추가합니다. 이 정책은 다음 권한을 부여합니다.
-
Amazon EC2 인스턴스 및 해당 상태 설명
-
인스턴스 프로파일 정보 검색
-
대상 인스턴스에서 Systems Manager Agent 연결 확인
-
인스턴스에서 조사 명령을 실행하기 위해
ssm:SendCommand실행
EC2 Triage를 사용하면 AWS 보안 인시던트 대응 엔지니어가 활성 보안 인시던트 중 실행 중인 Amazon EC2 인스턴스에서 휘발성 포렌식 데이터를 수집할 수 있습니다. 이 데이터에는 실행 중인 프로세스, 네트워크 연결, 로그인한 사용자 및 인스턴스가 종료되거나 중지될 경우 손실될 수 있는 기타 운영 체제 아티팩트가 포함될 수 있습니다.
