Apply the machine config for user access times by executing the following:

for mcpool in $(oc get mcp -oname | sed "s:.*/::" ); do
echo "apiVersion: machineconfiguration.openshift.io/v1
kind: MachineConfig
metadata:

Check Contents

Verify the Red Hat Enterprise Linux CoreOS (RHCOS) is configured to generate audit records showing starting and ending times for user access by executing the following:

for node in $(oc get node -oname); do oc debug $node -- chroot /host /bin/bash -c 'echo -n "$HOSTNAME "; grep -e "-k session" /etc/audit/audit.rules' 2>/dev/null; done

Confirm the following rules exist on each node:

-w /var/log/btmp -p wa -k session
-w /var/log/utmp -p wa -k session

If the above rules are not listed on each node, this is a finding.
