CIS Red Hat OpenShift Container Platform Benchmark v1.8.0 - Control 1.1.19

Profile Applicability

• Level: 1

Description

Ensure that the OpenShift PKI directory and file ownership is set to root:root.

Rationale

OpenShift makes use of a number of certificates as part of its operation. You should verify the ownership of the directory containing the PKI information and all files in that directory to maintain their integrity. The directory and files should be owned by root:root.

Impact

None

Audit Procedure

Keys for control plane components deployed as static pods, kube-apiserver, kube-controller-manager, and openshift-kube-scheduler are stored in the directory /etc/kubernetes/static-pod-certs/secrets. The directory and file ownership are set to root:root.

Run the following command.

# Should return root:root for all files and directories

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 d -wholename '*/secrets*' -exec stat -c %U:%G {} \;
        oc exec -n openshift-kube-apiserver $i -c kube-apiserver -- \
        find /etc/kubernetes/static-pod-certs -type f -wholename '*/secrets*' -exec stat -c %U:%G {} \;
        echo $i static-pod-resources
        oc exec -n openshift-kube-apiserver $i -c kube-apiserver -- \
        find /etc/kubernetes/static-pod-resources - d -wholename  -  -c %U:%G {} \;
        oc  -n openshift-kube-apiserver  -c kube-apiserver -- \
        find /etc/kubernetes/static-pod-resources - f -wholename  -  -c %U:%G {} \;
