AWS CloudFormation Misconfiguration: Missing CloudTrail Log Validation

JSON
YAML

Abstract

이 템플릿은 로그 파일 검증이 없는 추적을 정의합니다.

Explanation

기본적으로 CloudTrail 로그 파일검증이 비활성화되어 조사자가 CloudTrail 로그 파일에 대한 외부 변조가 없었음을 확신할 수 없습니다.

이에 따른 직접적인 결과는 필요한 권한을 가진 공격자가 CloudTrail 로그를 수정하여 유해한 구성 변경을 수행하고 자신의 흔적을 덮을 수 있다는 것입니다.

예제 1: 다음은 EnableLogFileValidation을 false로 설정하여 로그 파일 검증이 비활성화된 추적의 예제입니다. 또한 속성을 생략하면 기본값이 false로 설정됩니다.
