Kubernetes Misconfiguration: Privileged Container

Abstract
Kubernetes 容器可以在特权模式下运行。
Explanation
默认情况下，拒绝 Kubernetes 容器访问主机上的所有设备。privileged 字段允许容器拥有与主机上运行的其他流程几乎相同的权限。这扩大了攻击面，且违反了以最低权限运行映像的原则。

示例 1：Pod 通过设置 privileged: true 在特权模式下运行。

...
kind: Pod
...
spec:
  containers:
    - name: ...
      image: ...
      securityContext:
         privileged: true
...
