 Applicability of Interfaces to Network Security Functions to Network-
                        Based Security Services
                   draft-ietf-i2nsf-applicability-07

Abstract

   This document describes the applicability of Interface to Network
   Security Functions (I2NSF) to network-based security services in
   Network Functions Virtualization (NFV) environments, such as
   firewall, deep packet inspection, or attack mitigation engines.

1.  Introduction

   Interface to Network Security Functions (I2NSF) defines a framework
   and interfaces for interacting with Network Security Functions
   (NSFs).  The I2NSF framework allows heterogeneous NSFs developed by
   different security solution vendors to be used in the Network
   Functions Virtualization (NFV) environment [ETSI-NFV] by utilizing
   the capabilities of such products and the virtualization of security
   functions in the NFV platform.  In the I2NSF framework, each NSF
   initially registers the profile of its own capabilities into the
   system in order for themselves to be available in the system.  In
   addition, the Security Controller is validated by the I2NSF Client
   (also called I2NSF User) that the user is employing, so that the user
