            I2NSF Consumer-Facing Interface YANG Data Model
            draft-ietf-i2nsf-consumer-facing-interface-dm-02

Abstract

   This document describes a YANG data model for the Consumer-Facing
   Interface between an Interface to Network Security Functions (I2NSF)
   User and Security Controller in an I2NSF system in a Network
   Functions Virtualization (NFV) environment.  The data model is
   required for enabling different users of a given I2NSF system to
   define, manage, and monitor security policies for specific flows
   within an administrative domain.
