    Configuration of Advanced Security Functions with I2NSF Security
                               Controller
                     draft-dong-i2nsf-asf-config-01

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.  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.  With the
   variety and complexity of the advanced security functions, it is
   hardly to define all the interfaces to configure each advanced
