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: Automated iptables Management Disabled

Abstract
La configuración de Kubelet evita que Kubelet configure iptables.
Explanation
De forma predeterminada, Kubelets realiza automáticamente los cambios necesarios en iptables según las opciones de red en las configuraciones de Pod. Al establecer makeIPTablesUtilChains en enabled:false en una configuración de Kubelet se evita que Kubelet administre el tráfico de red entre los contenedores y el resto del mundo. Esto evita que Kubelet aplique los requisitos de seguridad de red necesarios y configure la conectividad solicitada por los contenedores.

Ejemplo 1: La siguiente configuración de Kubelet evita que un Kubelet realice los cambios necesarios en iptables debido al ajuste makeIPTablesUtilChains: false.

apiVersion: kubelet.config.k8s.io/v1beta1
kind: KubeletConfiguration
makeIPTablesUtilChains: false
