이 섹션에는 소스 코드 외부에 있지만 제작 중인 제품의 보안에는 여전히 중요한 내용이 모두 포함되어 있습니다. 이 섹션에서 다루는 문제들은 소스 코드와 직접적으로 관련이 없기 때문에 나머지 섹션과 분리했습니다.

AWS CloudFormation Misconfiguration: Insufficient API Gateway Logging

Abstract
구성이 감사 로깅 기능이 없는 서비스를 정의합니다.
Explanation
감사 기록이 없으면 보안 관련 사고를 감지하고 대응하는 능력이 제한되고 포렌식 조사가 불가능해집니다.

로깅 기능의 효율성을 떨어뜨리는 구성 설정에는 다음을 비롯한 여러 가지가 포함됩니다.
- 의도적인 감사 로깅 비활성화
- 특정 사용자, 그룹, 프로세스의 작업을 로깅 대상에서 제외
- 부적절한 방식으로 로그 무결성 보호
- 선택적 감사 로깅 미활성화
- 로그 샘플링 비율 하향 조정
