CJW> What's your solution? There's no one single answer. That's the whole point. The closest thing to a single answer would be "shift the cost of failure to the responsible party", but that's still insufficient. One must use many tactics -- prefix-list, filter-list, customer education, SAV, etc. -- and expect the same from upstreams, peers, and downstreams. Note that it's much easier to ask something of others when one has demonstrated willingness to do the same. Software vendors should be held more accountable for exploitable bugs that go unfixed. Admins should be held more accountable for systems that go unpatched. I realize not every car owner is a mechanic, but car owners who drive oil-burning, tailpipe-dragging jalopies with no headlights quickly learn that's no excuse. What about using a non-executable stack segment in $os on platforms where that's possible/necessary? Teaching about buffer overruns and race conditions in elementary programming classes sounds worthy to me, too. In short: My solution is for all these _parts_ of the answer to receive the attention and action they deserve. It's a bit harder than griping on NANOG about the lack of turnkey answer every three weeks, but probably at least effective enough to warrant a bit of attention. People gripe about the cost of exploits and attacks, yet complain about the costs of preventative measures. If the preventative measures are too expensive, then evidently the consequences are acceptable. That said, I'm eagerly awaiting your silver bullet. (Or are you part of the problem?)
