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: Missing PodSecurityPolicy Admission Controller

Abstract
El comando para iniciar un servidor de API de Kubernetes no habilita el controlador de admisión PodSecurityPolicy.
Explanation
La ausencia de un controlador de admisión PodSecurityPolicy es indicativo de controles de seguridad débiles, a menos que exista una herramienta alternativa de cumplimiento de políticas para Kubernetes, como K-Rail, Kyverno, OPA/Gatekeeper. El controlador de admisión PodSecurityPolicy hace cumplir las políticas de seguridad de Pod que especifican los atributos de Pod relacionados con la seguridad permitidos en un clúster. Por ejemplo, con PodSecurityPolicy puede prohibir contenedores privilegiados y no permitir la escalada de privilegios de forma predeterminada cada vez que se crea un Pod.

Ejemplo 1: La siguiente definición de Pod inicia un servidor de API de Kubernetes sin habilitar el controlador de admisión PodSecurityPolicy.

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