Observation from CISv1.4 pdf:
1.1.9 Ensure that the Container Network Interface file permissions are set to 600 or more restrictive
“Container Network Interface provides various networking options for overlay networking.
You should consult their documentation and restrict their respective file permissions to maintain the integrity of those files. Those files should be writable by only the administrators on the system.”
 
To conform with CIS benchmarksChange, the /var/run/multus/cni/net.d/*.conf files on nodes should be updated to 600.
