1.1.10 Ensure that the Container Network Interface file ownership is set to root:root (Manual)
Profile Applicability
Description
Ensure that the Container Network Interface files have ownership set to root:root.
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 owned by root:root.
Impact
None
Audit
Run the below command (based on the file location on your system) on the Control Plane node. For example,
stat -c %U:%G <path/to/cni/files>
Verify that the ownership is set to root:root.
Remediation
Run the below command (based on the file location on your system) on the Control Plane node. For example,
chown root:root <path/to/cni/files>
Default Value
NA
