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 NodeRestriction Admission Controller

YAML

Abstract

Kubernetes API サーバーを起動するコマンドが、NodeRestriction アドミッションコントローラーを有効にしません。

Explanation

NodeRestriction アドミッションコントローラーを、Kubernetes API サーバー用に常に有効にしてください。NodeRestriction アドミッションコントローラーは、すべての Kubelet に対して Node オブジェクトと Pod オブジェクトを変更することを制限するとともに、機密性の高いシステムオブジェクトへのアクセスを拒否します。これにより、侵害されたノードが Kubernetes クラスターの他のノードで特権を取得するのを防ぎます。

例 1: 次の Pod 定義では、NodeRestriction アドミッションコントローラーを有効にせずに、Kubernetes API サーバーを起動します。


apiVersion: v1
kind: Pod
...
spec:
  containers:
  - command:
    - kube-apiserver
    ...
    - --enable-admission-plugins=PodSecurityPolicy
    ...
