Title

The Kubernetes API Server audit log path must be set. (Cat II impact)

Discussion

Kubernetes API Server validates and configures pods and services for the API object. The REST operation provides frontend functionality to the cluster share state. Audit logs are necessary to provide evidence in the case the Kubernetes API Server is compromised requiring Cyber Security Investigation. To record events in the audit log the log path value must be set.

Check Content

Change to the /etc/kubernetes/manifests/ directory on the Kubernetes Control Plane. Run the command: grep -i audit-log-path * If the setting audit-log-path is not set in the Kubernetes API Server manifest file or it is not set to a valid path, this is a finding.

Fix Text

Edit the Kubernetes API Server manifest file in the /etc/kubernetes/manifests directory on the Kubernetes Control Plane. Set the value of "--audit-log-path" to valid location.
