            I2NSF Consumer-Facing Interface YANG Data Model
            draft-ietf-i2nsf-consumer-facing-interface-dm-12

Abstract

   This document describes an information model and 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
   information model defines various types of managed objects and the
   relationship among them needed to build the interface.  The
   information model is based on the "Event-Condition-Action" (ECA)
   policy model defined by a capability information model for I2NSF
   [I-D.ietf-i2nsf-capability], and the data model is defined for
   enabling different users of a given I2NSF system to define, manage,
   and monitor security policies for specific flows within an
   administrative domain.
