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

Kubernetes Misconfiguration: NamespaceLifecycle Enforcement Disabled

YAML

Abstract

The NamespaceLifecycle admission controller in a Kubernetes API server is disabled.

Explanation

The deletion of Kubernetes namespace removes all objects in that namespace, including Pods and services. The NamespaceLifecycle admission controller maintains the integrity of Kubernetes systems in two ways. First, it prevents objects from being created in non-existent namespaces or in namespaces undergoing termination. Second, it prevents system reserved namespaces, which contain Kubernetes critical services, from being deleted.

The NamespaceLifecycle admission controller is enabled by default but the command to start the Kubernetes API server has disabled it with the --disable-admission-plugin flag.

Example 1: The following configuration starts a Kubernetes API server. The presence of the NamespaceLifecycle included in the --disable-admission-plugins flag disables the NamespaceLifecycle admission controller.


...
kind: Pod
...
spec:
  containers:
  - command:
    - kube-apiserver
    ...
    - --disable-admission-plugins=...,NamespaceLifecycle,...
    ...
