1.1.9 Ensure that the Container Network Interface file permissions are set to 600 or more restrictive (Manual)
Profile Applicability
Description
Ensure that the Container Network Interface files have permissions of 600 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.
Impact
None
Audit
Run the below command (based on the file location on your system) on the Control Plane node. For example,
stat -c %a <path/to/cni/files>
Verify that the permissions are 600 or more restrictive.
Remediation
Run the below command (based on the file location on your system) on the Control Plane node. For example,
chmod 600 <path/to/cni/files>
Default Value
NA
