DNS

So, how about that DNS vulnerability, huh?

Brings back memories of the days gone by when vulnerabilities and attacks regularly threatened the entire internet rather than being as targeted as they are now. Well, I guess this time there's a pretty ubiquitous hole that can be used for targeted attacks until folks patch. If they haven't they're nuts.

Meanwhile... Dan K suggests using OpenDNS since they were fixed before many ISPs. Having one place provide DNS to a lot of people kind of paints a giant target on their backs but then again that's no different than any major ISP's DNS servers. OpenDNS beat a lot of ISP's to the punch in patching so maybe that is an indiciation of the kind of shop they run. Plus they offer content filtering, typo fixing, and phishing protection features. Nice.

But, you probably knew all that, right?

So why didn't you tell me? :)

CanSecWest hacking contest here. OS X Leopard vs. Vista vs. Linux. Entertaining, but hope no one actually thinks the results will be conclusive. You certainly wouldn't make risk based decisions on the results... would you?
Anymore, with true 0-days becoming more and more commonplace, even though your risk may be lowered a bit by using an OS that seems to have fewer vulnerabilities discovered per year, it's still not worth comparing until the reliability factor goes way, way up. Until that number reaches one remotely exploitable vulnerability every 5 or 10 years (like OpenBSD, say?), you still need to "worry" and stack up your defense in depth security controls.

We're still at a point in OS software reliability where it's like comparing a 70's Italian roadster to a 70's British roadster. One may drive an extra day or two longer before breaking down but who cares? They both spend more time in the shop than on the road.
