No, not that kind. :-)

BGP security is a vexed topic—people have been working in this area for over twenty years with some effect, but we continuously find new problems to address. Today I am looking at a paper called BGP Communities: Can of Worms, which analyses some of the security problems caused by current BGP community usage in the ‘net. The point I want to think about here, though, is not the problem discussed in the paper, but rather some of the larger problems facing security in routing.
