     Network Configuration Protocol (NETCONF) Access Control Model
                    draft-ietf-netconf-rfc6536bis-01

Abstract

   The standardization of network configuration interfaces for use with
   the Network Configuration Protocol (NETCONF) or RESTCONF protocol
   requires a structured and secure operating environment that promotes
   human usability and multi-vendor interoperability.  There is a need
   for standard mechanisms to restrict NETCONF or RESTCONF protocol
   access for particular users to a pre-configured subset of all
   available NETCONF or RESTCONF protocol operations and content.  This
   document defines such an access control model.

   This document obsoletes RFC 6536.
