CIS Kubernetes Benchmark v1.11.1 - Control 1.1.2

Profile Applicability

Level: 1 - Master Node

Description

Ensure that the API server pod specification file ownership is set to root:root.

Rationale

The API server pod specification file controls various parameters that set the behavior of the API server. You should set its file ownership to maintain the integrity of the file. The file should be owned by root:root.

Impact

None

Audit

Run the below command (based on the file location on your system) on the Control Plane node. For example,

stat -c %U:%G /etc/kubernetes/manifests/kube-apiserver.yaml

Verify that the ownership is set to root:root.

Remediation

Run the below command (based on the file location on your system) on the Control Plane node. For example,

chown root:root /etc/kubernetes/manifests/kube-apiserver.yaml

Default Value

By default, the kube-apiserver.yaml file ownership is set to root:root.
