Question #1

オンプレミスデータセンターの内部監査において、ネットワーク防御担当者は、コアアプリケーションとデータベースサービスをホストする複数のWindowsおよびLinuxサーバーにおけるユーザー権限を調査した。監査の結果、サーバー管理チームに所属していない複数のヘルプデスク技術者に、ローカル管理者権限、サービスアカウントの変更、複数の内部システムの構成設定へのアクセスといった、高い権限が付与されていることが判明した。
これらの権限は、ユーザーパスワードのリセットやクライアントソフトウェアのインストールといった運用サポート業務に必要な範囲をはるかに超えています。セキュリティ上の影響を懸念した防御担当者は、ITマネージャーと協力して新しいポリシーを導入しました。改訂された構成では、権限は事前に定義された運用ロールに基づいて厳密に割り当てられ、ユーザーは職務を遂行するために必要な特定のリソースにのみアクセスできるようになっています。この場合、アクセス制御のどの原則が直接適用されているでしょうか?

  • A. 最小特権の原則
  • B. 職務分担
  • C. 任意アクセス制御
