To quote Bruce Schneier quoting an NSA maxim, attacks only get better; they never get worse. We now have running code of one way to do this. I think most NANOG readers can see many more ways to do it. A real solution will take years to deploy, but it will never happen if we don't start. And we want to have the solution out there *before* we see serious attacks on BGP.
Again, thank you -- it was really nice work.
Seems like we *could* get a large part of the way there if people were only checking the information in question. While not the long-term fix of being able to prove authorization to advertise space, simply requiring a LOA at the edge, and requiring IRR further in, and keeping records of what was advertised, would seem to be a worthwhile improvement on the current state of affairs. Total prevention is a very rough goal, so making it more difficult, combined with being able to identify when someone did something bad, really ought to be a worthwhile interim goal, and I've wondered for a long time why this isn't being done. ...
