Reino: Security Features

La seguridad de un software no es un software de seguridad. Nos preocupamos de cuestiones como la autenticación, el control de acceso, la confidencialidad, la criptografía y la gestión de privilegios.

Kubernetes Misconfiguration: Privileged Container

YAML

Abstract

Un contenedor de Kubernetes puede ejecutarse en modo privilegiado.

Explanation

De forma predeterminada, a un contenedor de Kubernetes se le niega el acceso a todos los dispositivos del host. El campo privileged permite al contenedor casi todos los mismos privilegios que otros procesos que se ejecutan en el host. Esto expande la superficie de ataque e infringe el principio de ejecutar imágenes con privilegios mínimos.

Ejemplo 1: El pod se ejecuta en modo privilegiado estableciendo privileged: true.


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