Ensure kubevirt cache directory permission is set to 755 or more restrictive

MediaNivel 1Automatizadaopenshift-virt

Descripción

Setting the kubevirt private directory to 755 or more restrictive limits access to security related administrative functionality to approved administrators. Audit: Passes when /var/run/kubevirt-private in every virt-handler pod is mode 755 or more restrictive; a pod where the directory does not exist is not applicable. Requires oc logged in to the cluster with read access.
