HI Folks,

One of our colleagues from AUSNOG mentioned this, and I thought it'd be worth reposting here as I'd imagine it's required reading for many of you (which I'm sure you have of course!).

RFC7454 - "BGP Operations and Security"

https://tools.ietf.org/html/rfc7454

"Abstract

The Border Gateway Protocol (BGP) is the protocol almost exclusively
used in the Internet to exchange routing information between network
domains.�� Due to this central nature, it is important to understand
the security measures that can and should be deployed to prevent
accidental or intentional routing disturbances.

This document describes measures to protect the BGP sessions itself
such as Time to Live (TTL), the TCP Authentication Option (TCP-AO),
and control-plane filtering.�� It also describes measures to better
control the flow of routing information, using prefix filtering and
automation of prefix filters, max-prefix filtering, Autonomous System
(AS) path filtering, route flap dampening, and BGP community
scrubbing."
