# CIS Red Hat OpenShift Container Platform Benchmark v1.9.0 - Control 1.1.21

## Profile Applicability

- **Level:** 1

## Description

Ensure that the OpenShift PKI key files have permissions of `600`.

## Rationale

OpenShift makes use of a number of key files as part of the operation of its components. The permissions on these files should be set to `600` to protect their integrity and confidentiality.

## Impact

None

## Audit Procedure

Keys for control plane components like `kube-apiserver`, `kube-controller-manager`, `kube-scheduler` and `etcd` are stored with their respective static pod configurations in the directory `/etc/kubernetes/static-pod-certs/secrets`. Key files all have permissions `600`.

Run the following command.

```bash
for i in $(oc -n openshift-kube-apiserver get pod -l app=openshift-kube-apiserver -o jsonpath='{.items[*].metadata.name}')
do
      echo $i static-pod-certs
      oc exec -n openshift-kube-apiserver $i -c kube-apiserver -- \
      find /etc/kubernetes/static-pod-certs -type f -wholename '*/secrets/*.key' -exec stat -c %a {} \;
done
```

Verify that the permissions are `600`.

## Remediation

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

## Default Value

By default, the keys used by OpenShift are set to have permissions of `600`
