In case there are specific aspects for the underlying scenarios or applications, these are described in an NF specific chapters. This document contains recommendations (short statements on how to operate and manage the CNC software) and procedures (step-by-step instructions to assist the customer in tailoring or hardening the CNC system).

In the few cases where this isn't possible, an installion time checklist procedure is created and listed on the Cloud Native Core Security Checklist. It is a short list of post-installation hardening activities that must be performed by the customer before placing the system into operation. The recommendations and other procedures found in this document are optional, and must be considered in the context of your organization's approved security policies.
