AWS CloudFormation Misconfiguration: Improper RDS Network Access Control

JSON
YAML

Abstract

템플릿이 액세스 제한이 충분하지 않은 DBSecurityGroup을 정의합니다.

Explanation

느슨한 액세스 구성은 시스템을 불필요하게 노출시키고 조직의 공격 표면을 확장합니다. 공개 상호 작용이 가능한 서비스는 악의적인 엔터티의 거의 지속적인 검색 및 조사에 노출됩니다.

이는 노출된 서비스에 대한 제로데이 익스플로이트가 검색되어 게시되는 경우(예: Heartbleed) 특히 문제가 됩니다. 공격자는 패치되지 않고 노출된 시스템을 적극적으로 추적하고 검색하여 악용할 수 있습니다.
