        A standard process to quarantine and restore IoT Devices
                 draft-richardson-shg-un-quarantine-00

Abstract

   The Manufacturer Usage Description (MUD) is a tool to describe the
   limited access that a single function device such as an Internet of
   Things device might need.  The enforcement of the access control
   lists described protects the device from attacks from the Internet,
   and protects the Internets from compromised devices.

   This document details the process which occurs when a device is
   detected to have violated the stated policy.  The goal of these steps
   is to ensure that the device is correctly removed from operation,
   fixed, and if possible, restored to safe operation.
