                         Secure Device Install
                      draft-wkumari-opsawg-sdi-04

Abstract

   Deploying a new network device often requires that an employee
   physically travel to a datacenter to perform the initial install and
   configuration, even in shared datacenters with "smart-hands" type
   support.  In many cases, this could be avoided if there were a
   standard, secure way to initially provision the devices.

   This document extends existing auto-install / Zero-Touch Provisioning
   mechanisms to make the process more secure.
