What does this control test

This control enumerates external facing workloads, that have LoadBalancer or NodePort services and checks image vulnerability information to see if the image has critical vulnerabilities.

Remediation

Either update the container image to fix the vulnerabilities (if such fix is available) or reassess if this workload must be exposed to the outseide traffic. If no fix is available, consider periodic restart of the POD to minimize the risk of persistant intrusion. Use exception mechanism if you don't want to see this report again.
