1.1.15 Ensure that the scheduler.conf file permissions are set to 644 or more restrictive

Information

Ensure that the scheduler.conf file has permissions of 644 or more restrictive.

Rationale:

The scheduler.conf file is the kubeconfig file for the Scheduler. You should restrict its file permissions to maintain the integrity of the file. The file should be writable by only the administrators on the system.

Impact:

None

Solution

Run the below command (based on the file location on your system) on the master node. For example,

chmod 644 /etc/kubernetes/scheduler.conf

Default Value:

By default, scheduler.conf has permissions of 640.
