1.  Introduction

   This document defines the terminology for the Interface to Network
   Security Functions (I2NSF) effort.  This section provides some
   background on I2NSF; a detailed problem statement can be found in
   [RFC8192]. Motivation and comparison to previous work can be found
   in [I-D.ietf-i2nsf-gap-analysis].

   Enterprises are now considering using network security functions
   (NSFs) hosted by service providers due to the growing challenges and
   complexity in maintaining an up-to-date secure infrastructure that
   complies with regulatory requirements, while controlling costs.  The
   hosted security service is especially attractive to small- and
   medium-size enterprises who suffer from a lack of security experts
   to continuously monitor, acquire new skills and propose immediate
   mitigations to ever increasing sets of security attacks.  Small- and
   medium-sized businesses (SMBs) are increasingly adopting cloud-based
   security services to replace on-premises security tools, while larger
   enterprises are deploying a mix of traditional (hosted) and cloud-
   based security services.

   To meet the demand, more and more service providers are providing
   hosted security solutions to deliver cost-effective managed security
   services to enterprise customers.  The hosted security services are
   primarily targeted at enterprises, but could also be provided to
   mass-market customers as well.  NSFs are provided and consumed in
   increasingly diverse environments.  Users of NSFs may consume
   network security services hosted by one or more providers, which
   may be their own enterprise, service providers, or a combination
   of both.

   It is out of scope in this document to define an exhaustive list of
