Azure ARM Misconfiguration: Improper Blob Storage Access Control

Bicep
JSON

Abstract

이 템플릿은 익명 액세스를 허용하는 Azure Blob Storage 컨테이너를 정의합니다.

Explanation

기본적으로 Azure Blob Storage 컨테이너는 해당하는 Blob에 대한 익명 액세스를 차단합니다.

충분하지 않은 액세스 구성은 시스템을 노출시키고 조직의 공격 표면을 확장합니다. 공개 액세스를 허용하는 리소스는 민감한 데이터를 의도치 않게 유출할 수 있습니다.

예제 1: 다음 예제 템플릿은 publicAccess 속성을 Container로 설정하여 Azure Blob Storage 컨테이너를 정의합니다. 이렇게 하면 컨테이너의 모든 blob 및 데이터에 익명으로 액세스할 수 있습니다.
