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 Service Account Token Authentication

Abstract
No se especifica la clave privada para firmar tokens de cuenta de servicio.
Explanation
Un servidor de API de Kubernetes puede autenticar solicitudes de API mediante tokens de cuenta de servicio. Dichos tokens son generados y firmados por el controlador de tokens de Kubernetes. Utilice la marca --service-account-private-key-file para especificar la clave para firmar el token.

Ejemplo 1: La siguiente configuración inicia un administrador de controlador de Kubernetes sin la marca --service-account-private-key-file.

apiVersion: v1
kind: Pod
...
spec:
  containers:
    - command:
        - kube-controller-manager
    image: k8s.gcr.io/kube-controller-manager:v1.9.7
...
