  The Data Model of Network Infrastructure Device Data Plane Security
                                Baseline
               draft-xia-sacm-nid-dp-security-baseline-01

Abstract

   This document proposes one part of the security baseline YANG for
   network infrastructure device (i.e., router, switch, firewall, etc):
   data plane security baseline.  The companion documents [I-D.ietf-lin-
   sacm-nid-mp-security-baseline], [I- D.ietf-dong-sacm-nid-infra-
   security-baseline] cover other parts of the security baseline YANG
   for network infrastructure device respectively: management plane
   security baseline, infrastructure layer security baseline.

1.  Introduction

1.1.  Objective

   Network security is an essential part of the overall network
   deployment and operation.  Due to the following reasons, network
   infrastructure devices (e.g. switch, router, firewall) are always the
   objective and exploited by the network attackers, which bring damages
   to the victim network:

   o  The existence of a lot of unsafe access channels: for the history
      reason, some old and unsafe protocols still run in the network
      devices, like: SNMP v1/v2, Telnet, etc, and are not mandatory to
      be replaced by the according safer protocols (SNMP v3, SSH).
