    Requirements for Client-Facing Interface to Security Controller
            draft-ietf-i2nsf-client-facing-interface-req-04

Abstract

   This document captures requirements for Client-Facing interface to
   the Security Controller as defined by [I-D.ietf-i2nsf-framework].
   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 the
   User Community.  This gives ability to decouple policy definition
   from policy enforcement on a specific security functional element, be
   it a physical or virtual.
