Ensure kubevirt seccomp profile file permission is set to 700 or more restrictive

OrtaDüzey 1Otomatikopenshift-virt

Açıklama

Setting the kubevirt Secure Computing Mode (seccomp) file permissions to 700 or more restrictive limits access to security related administrative functionality to approved administrators. Audit: Passes when the seccomp profile file of every virt-handler pod is mode 700 or more restrictive; a pod where the file does not exist (Secure Computing Mode feature gate not enabled) is not applicable. Requires oc logged in to the cluster with read access.
