 Applicability of Interfaces to Network Security Functions to Network-
                        Based Security Services
                   draft-ietf-i2nsf-applicability-11

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).  Note that an NSF is defined as software that provides a set
   of security-related services, such as (i) detecting unwanted
   activity, (ii) blocking or mitigating the effect of such unwanted
   activity in order to fulfil service requirements, and (iii)
   supporting communication stream integrity and confidentiality
   [i2nsf-terminology].

   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
