Container Network Interface file permissions are set to 644 or more restrictive
Set up the kubernetes integration.
Description
Ensure that the Container Network Interface files have permissions of 644 or more restrictive.
Rationale
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.
Audit
Run the below command (based on the file location on your system) on the master node.
stat -c %a <path/to/cni/files>
Verify the permissions are 644 or more restrictive.
Run the below command (based on the file location on your system) on the master node. For example, chmod 644 <path/to/cni/files>
Impact
