This document describes a threat model for the context in which
External Border Gateway Protocol (EBGP) path security mechanisms will
be developed.  The threat model includes an analysis of the Resource
Public Key Infrastructure (RPKI) and focuses on the ability of an
Autonomous System (AS) to verify the authenticity of the AS path info
received in a BGP update.  We use the term "PATHSEC" to refer to any
BGP path security technology that makes use of the RPKI.  PATHSEC
will secure BGP, consistent with the inter-AS security focus of the
RPKI.

The document characterizes classes of potential adversaries that are
considered to be threats and examines classes of attacks that might
be launched against PATHSEC.  It does not revisit attacks against
unprotected BGP, as that topic has already been addressed in the
BGP-4 standard.  It concludes with a brief discussion of residual
vulnerabilities.

This document is a product of the Secure Inter-Domain Routing Working Group of the IETF.
