Kingdom: Security Features

Software security is not security software. Here we're concerned with topics like authentication, access control, confidentiality, cryptography, and privilege management.

Kubernetes Misconfiguration: Automated iptables Management Disabled

Abstract
The Kubelet configuration prevents the Kubelet from configuring iptables.
Explanation
By default, Kubelets automatically make the required changes to iptables based on the networking options in Pod configurations. Setting makeIPTablesUtilChains to enabled:false in a Kubelet configuration prevents the Kubelet from managing network traffic between containers and the rest of the world. This prevents the Kubelet from enforcing the necessary network security requirements and setting up the connectivity requested by containers.

Example 1: The following Kubelet configuration prevents a Kubelet from making the required changes to iptables because of the setting makeIPTablesUtilChains: false.

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