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

SedangLevel 1Otomatisopenshift-virt

Deskripsi

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.

command -v oc >/dev/null 2>&1 || exit 1; bad=0; n=0; for pod in $(oc get pod -n openshift-cnv -l kubevirt.io=virt-handler --no-headers -o custom-columns=":metadata.name" 2>/dev/null); do n=$((n+1)); m=$(oc exec -n openshift-cnv "$pod" -c virt-handler -- sh -c 'f=/proc/1/root/var/lib/kubelet/seccomp/kubevirt/kubevirt.json; [ -e "$f" ] && stat -c %a "$f" || echo absent' 2>/dev/null); case "$m" in absent) ;; [0-7][0-7][0-7]|[0-7][0-7][0-7][0-7]) [ $((8#$m & 8#077)) -eq 0 ] || bad=1;; *) bad=1;; esac; done; [ "$n" -gt 0 ] || exit 1; [ "$bad" -eq 0 ] && echo compliant || echo noncompliant

Output yang diharapkan: compliant

Cara perbaikan
