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。
Kubernetes Misconfiguration: Missing Kubelet Authorization
Abstract
Kubelet は、リクエストの承認を必要としません。
Explanation
Kubelet は、
例 1: 承認モードが
AlwaysAllow モードまたは Webhook モードを使用してリクエストを承認します。未指定の承認モードはデフォルトで AlwaysAllow になります。Kubelet は、すべてのリクエストを許可する AlwaysAllow モードでは承認チェックを実行しません。Kubelet はワーカー マシンのワークロードを管理する Kubernetes の主要なエージェントであるため、攻撃者は、制御されないリクエストを使用して、保護が不十分でセキュリティが重要なサービス API にアクセスできます。例 1: 承認モードが
AlwaysAllow に設定されているため、Kubelet は承認チェックを実行しません。
apiVersion: kubelet.config.k8s.io/v1beta1
