Abstract

   This document provides an overview of a security extension to the
   Border Gateway Protocol (BGP) referred to as BGPsec.  BGPsec improves
   security for BGP routing.

1. Introduction

   BGPsec (Border Gateway Protocol Security) is an extension to the
   Border Gateway Protocol (BGP) that provides improved security for BGP
   routing [RFC4271]. This document contains a brief overview of BGPsec
   and its envisioned usage.

   A more detailed discussion of BGPsec is provided in the following set
   of documents:

     *  [RFC7132]:

        A threat model describing the security context in which BGPsec
        is intended to operate.

     *  [RFC7353]:

        A set of requirements for BGP path security, which BGPsec is
        intended to satisfy.

     *  [I-D.sidr-bgpsec-protocol]:

        A standards track document specifying the BGPsec extension to
        BGP.

     *  [I-D.sidr-as-migration]:

        A standards track document describing how to implement an AS
        Number migration while using BGPsec.

     *  [I-D.sidr-bgpsec-ops]:

        An informational document describing operational considerations.

     * [I-D.sidr-bgpsec-pki-profiles]:

        A standards track document specifying a profile for X.509
        certificates that bind keys used in BGPsec to Autonomous System
        numbers, as well as associated Certificate Revocation Lists
        (CRLs), and certificate requests.
