Much like most other problems in technology, securing the reachability (routing) information in the internet core as much or more of a people problem than it is a technology problem. While BGP security can never be perfect (in an imperfect world, the quest for perfection is often the cause of a good solution’s failure), there…
At NANOG on the Road (NotR) in September of 2018, I participated in a panel on BGP security—specifically the deployment of Route Origin Authentication (ROA), with some hints and overtones of path validation by carrying signatures in BGP updates (BGPsec). This is an area I have been working in for… 20 years? … at this…
The Resource Public Key Infrastructure (RPKI) system is designed to prevent hijacking of routes at their origin AS. If you don’t know how this system works (and it is likely you don’t, because there are only a few deployments in the world), you can review the way the system works by reading through this post…
I was recently invited to a webinar for the RIPE NCC about the future of BGP security. The entire series is well worth watching; I was in the final session, which was a panel discussion on where we are now, and where we might go to make BGP security better.
Yet another protocol episode over at the Network Collective. This time, Nick, Jordan, Eyvonne and I talk about BGP security.
From time to time, someone publishes a new blog post lauding the wonderfulness of BGPsec, such as this one over at the Internet Society. In return, I sometimes feel like I am a broken record discussing the problems with the basic idea of BGPsec—while it can solve some problems, it creates a lot of new…
BGP security: where we are now, where we are going, as presented at LACNOG 26 in November of 2016.
What would it take to secure BGP? Let’s begin where any engineering problem should begin: what problem are we trying to solve? This series of posts walks through a wide range of technical and business problems to create a solid set of requirements against which to measure proposed solutions for securing BGP in the global…
The next proposed (and actually already partially operational) system on our list is the Router Public Key Infrastructure (RPKI) system, which is described in RFC7115 (and a host of additional drafts and RFCs). The RPKI systems is focused on solving a single solution: validating that the originating AS is authorized to originate a particular prefix.…
