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 Certificate Authentication

Abstract
Kubelet の HTTPS エンドポイントに対する X509 クライアント証明書の認証が定義されていません。
Explanation
Kubelet はクライアントを認証できますが、クライアント証明書の検証に使用される認証局 (CA) バンドルが Kubelet 構成で定義されていません。Kubelet はワーカー マシンのワークロードの管理に使用される Kubernetes の主要なエージェントであるため、攻撃者は、匿名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: 次の Kubelet 構成には、クライアント証明書の検証に使用される CA バンドルを指定する、clientCAFile フィールドが含まれていません。

apiVersion: kubelet.config.k8s.io/v1beta1
kind: KubeletConfiguration
