    Configuration of Advanced Security Functions with I2NSF Security

Abstract

   This draft defines a network security function (NSF-) facing
   interface of the security controller for the purpose of configuring
   some advanced security functions.  These advanced security functions
   include antivirus, anti-ddos, and intrusion prevention system (IPS).
   The interface is presented in a YANG data model fashion and can be
   used to deploy a large amount of NSF blocks that all support above
   mentioned functions in the software defined network (SDN) based
   paradigm.

1.  Introduction

   I2NSF provides a technology and vendor independent way for a
   centralized security controller in a SDN environment to manage and
   configure the distributed NSFs [RFC8329].  The NSFs are automatically
   customized in a programmable manner via a standard interface [I-
   D.ietf-i2nsf-sdn-ipsec-flow-protection].  In the draft [I-D.ietf-
   i2nsf-nsf-facing-interface-dm], it proposed a generic NSF-facing
   interface to manage which action should be applied on which traffic.
   In addition, there is another draft that defined the NSF-facing
   interface for management, including configuration and monitoring, of
   IPsec SAs [I-D.ietf-i2nsf-sdn-ipsec-flow-protection].  In this
   document, we defined another NSF-facing interface for security
   controller to configure some advanced security functions including
   the antivirus, anti-ddos, and IPS profiles.
