       An Architecture for Security Management in I2NSF Framework
          draft-kim-i2nsf-security-management-architecture-00

Abstract

   This document describes an architecture for security management in
   the Interface to Network Security Functions (I2NSF) framework.  This
   security management architecture consists of I2NSF Client, Security
   Management System (i.e., Security Controller and Developer's
   Management System), and Network Security Functions (NSFs) in the
   I2NSF framework.  I2NSF Client consists of Application Logic, Policy
   Updater, and Policy Collector.  Security Controller consists of
   Security Policy Manager and NSF Capability Manager.  This document
   explains their missions and the processing of security management in
   a high level.  It also describes representative use cases, such as
   security management for the list of malware domains and security
   management for VoIP-VoLTE.

1.  Introduction

   To enforce a user's high-level security policy into the I2NSF
   framework [i2nsf-framework], I2NSF Client delivers such a policy to
   Security Controller via Client Facing Interface.  In this document,
