scope:

This Recommendation specifies a framework of software-defined security in software-defined networks (SDNs) and the network functions virtualization (NFV) networks. This Recommendation provides the following:

- analysis of the main security challenges including technical and operational aspects in telecom operators' SDN/NFV based networks;

- summarization of security requirements to address these challenges in SDN/NFV networks;

- introduction of the concept of 'software-defined security' based on identified requirements;

- definition of a framework for 'software-defined security' with functionality requirements for each component; and

- guidelines on implementation of software-defined security.
