Kubernetes Misconfiguration: Missing PodSecurityPolicy Admission Controller

YAML

Abstract

用于启动 Kubernetes API 服务器的命令不会启用 PodSecurityPolicy 准入控制器。

Explanation

缺少 PodSecurityPolicy 准入控制器表明安全控制较弱，除非 Kubernetes 有 K-Rail、Kyverno、OPA/Gatekeeper 等替代策略执行工具。PodSecurityPolicy 准入控制器强制执行 Pod 安全策略，这些策略用于指定群集中允许的安全相关 Pod 属性。例如，通过使用 PodSecurityPolicy，您可以在创建 Pod 时默认禁止特权容器并禁止特权提升。

示例 1：以下 Pod 定义启动了未启用 PodSecurityPolicy 准入控制器的 Kubernetes API 服务器。


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