    Requirements for Client-Facing Interface to Security Controller
            draft-ietf-i2nsf-client-facing-interface-req-01

Abstract

   This document captures requirements for Client-Facing interface to
   Security Controller.  The interface is expressed using objects and
   constructs understood by Security Admin as opposed to vendor or
   device specific expressions associated with individual product and
   feature.  This document identifies a broad set of requirements needed
   to express security policies based on User-constructs which are well
   understood by User Community.  This gives ability to decouple policy
   definition from policy enforcement on a specific element, be it a
   physical or virtual.
