Title

Kubernetes Controller Manager must disable profiling. (Cat II impact)

Discussion

Kubernetes profiling provides the ability to analyze and troubleshoot Controller Manager events over a web interface on a host port. Enabling this service can expose details about the Kubernetes architecture. This service must not be enabled unless deemed necessary.

Check Content

Change to the /etc/kubernetes/manifests/ directory on the Kubernetes Control Plane. Run the command: grep -i profiling * If the setting "profiling" is not configured in the Kubernetes Controller Manager manifest file or it is set to "True", this is a finding.

Fix Text

Edit the Kubernetes Controller Manager manifest file in the /etc/kubernetes/manifests directory on the Kubernetes Control Plane. Set the argument "--profiling value" to "false".
