AWS CloudFormation Misconfiguration: Improper S3 Bucket Network Access Control
Abstract
Amazon S3 버킷이 모든 S3 퍼블릭 액세스 차단 설정을 활성화하지 않고 만들어집니다.
Explanation
잘못된 구성으로 인한 S3 버킷의 공개 액세스는 데이터 침해의 주요 원인입니다.
S3 버킷은 기본적으로 공개 액세스를 차단하지만 권한이 있는 모든 사용자는 공개 액세스를 허용하도록 버킷 정책 또는 ACL(Access Control List)을 업데이트할 수 있습니다.
지나치게 허용적인 기존 버킷 정책 및 ACL로부터 보호하려면
S3 버킷은 기본적으로 공개 액세스를 차단하지만 권한이 있는 모든 사용자는 공개 액세스를 허용하도록 버킷 정책 또는 ACL(Access Control List)을 업데이트할 수 있습니다.
PublicAccessBlockConfiguration S3 속성에서 각각 BlockPublicPolicy 및 BlockPublicAcls 설정을 활성화하여 이 유형의 업데이트를 금지하십시오.지나치게 허용적인 기존 버킷 정책 및 ACL로부터 보호하려면
RestrictPublicBuckets 및 IgnorePublicAcls의 설정을 활성화합니다.References
