ETSI GR NFV-SEC 003 has been developed to describe the security and trust guidance that is unique to NFV development, architecture and operation. Guidance consists of items to consider that may be unique to the environment or deployment. Supplied guidance does not consist of prescriptive requirements or specific implementation details, which should be built from the considerations supplied.

Guidance is based on defined use cases, included in the present document, that are derived from the Security Problem Statement and are unique to NFV. Relevant external guidance will be referenced, where available.
