1.  Introduction

   This document proposes language for the the security consideration
   section for Yang modules from the I2RS Working group which utilize
   the I2RS protocol enhancements to the NETCONF/RESTCONF.  The I2RS
   protocol enhancement to the NETCONF/RESTCONF protocol must meet the
   protocol security requirements established in
   [I-D.ietf-i2rs-protocol-security-requirements], and the environment
