The Kubernetes kubelet staticPodPath must not enable static pods.
Allowing kubelet to set a staticPodPath gives containers with root access permissions to traverse the hosting filesystem. The danger comes when the container can create a manifest file within the /...Rule High Severity -

Kubernetes DynamicAuditing must not be enabled.
Protecting the audit data from change or deletion is important when an attack occurs. One way an attacker can cover their tracks is to change or delete audit records. This will either make the atta...Rule Medium Severity -

Kubernetes API Server must generate audit records that identify what type of event has occurred, identify the source of the event, contain the event results, identify any users, and identify any containers associated with the event.
Within Kubernetes, audit data for all components is generated by the API server. This audit data is important when there are issues, to include security incidents that must be investigated. To make...Rule Medium Severity -
