ソフトウェアのセキュリティは、セキュリティ ソフトウェアではありません。ここでは、認証、アクセス制御、機密性、暗号化、権限管理などのトピックについて説明します。

Azure Ansible Misconfiguration: Improper Blob Storage Access Control

Abstract
この Ansible タスクは、匿名アクセスを許可する Azure Blob ストレージ コンテナーを定義します。
Explanation
デフォルトでは、Azure BLOB ストレージ コンテナーは BLOB への匿名アクセスを防ぎます。

アクセス設定が不十分であると、システムが公開され、組織の攻撃対象領域が広がります。パブリック アクセスが可能なリソースは、意図せずに機密データを漏洩する可能性があります。

例 1: 次の Ansible タスクの例では、public_access パラメーターを container に設定して、Azure Blob ストレージ コンテナーを定義しています。これにより、コンテナーのすべての BLOB とデータに匿名でアクセスできます。

- name: Create container test
  azure_rm_storageblob:
    resource_group: testGroup
    storage_account_name: sa001
    container: testContainer
    ...
    public_access: container
    ...
