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.
