  The Data Model of Network Infrastructure Device Infrastructure Layer
                           Security Baseline

Abstract

   This document is one of the companion documents which describes the
   infrastructure layer security baseline YANG output for network
   infrastructure devices.  The infrastructure layer security baseline
   covers the security functions to secure the device itself, and the
   fundamental security capabilities provided by the device to the upper
   layer applications.  In this specific document, the integrity
   measurement, cryptography algorithms, key management, and certificate
   management are sorted out to generate the data model.
