# CIS Red Hat OpenShift Container Platform Benchmark v1.9.0 - Control 1.1.18

## Profile Applicability

- **Level:** 1

## Description

Ensure that the `kubeconfig` file ownership is set to `root:root`.

## Rationale

You should set the `kubeconfig` file ownership to maintain the integrity of the file. The file should be owned by `root:root`.

## Impact

None.

## Audit Procedure

Run the following command.

```bash
for i in $(oc get pods -n openshift-kube-controller-manager -l app=kube-controller-manager -oname)
  do
  oc exec -n openshift-kube-controller-manager $i -- \
  stat -c %U:%G /etc/kubernetes/static-pod-resources/configmaps/controller-manager-kubeconfig/kubeconfig
  done
```

Verify that the ownership is set to `root:root`.

## Remediation

No remediation required; file permissions are managed by the operator.

## Default Value

By default, the Controller Manager `kubeconfig` file ownership is set to `root:root`.
