I2NSF Consumer-Facing Interface YANG Data Model
draft-ietf-i2nsf-consumer-facing-interface-dm-06
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 organized based on the "Event-Condition-Action"
(ECA) policy model defined by a capability information model for
I2NSF [i2nsf-capability-im], 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.
