To recap (or rather, as they used to say in old television shows, “last time on ‘net Work…”), this series is looking at BGP security as an exercise (or case study) in understanding how to approach engineering problems. We started this series by asking three questions, the third of which was: What is it we…

In part 1 of this series, I pointed out that there are three interesting questions we can ask about BGP security. The third question I outlined there was this: What is it we can actually prove in a packet switched network? This is the first question I want dive in too—this is a deep dive,…

What would it take to secure BGP? Let’s begin where any engineering problem should begin: what problem are we trying to solve? In this network—in any collection of BGP autonomous systems—there are three sorts of problems that can occur at the AS level. For the purposes of this explanation, assume AS65000 is advertising 2001:db8:0:1::/64. While…
