Abstract

   The Network Security Functions (NSF) NSF-facing interface exists
   between the Service Provider's management system (or Security
   Controller) and the NSFs to enforce the security policy provisioning
   and network security status monitoring.  This document focuses on the
   monitoring part of it and proposes the information model (IM) for it.
   This IM is intended to function as a guideline to derive new data
   models from it and ensure interoperability between them.
