It seems that people are reluctant to do DNSSEC until there is a huge rollout across the world and the root zone is signed. Well guess what? It won't happen that way. It's going to happen in baby steps, one piece at a time. Eventually critical mass will be achieved. I'd like to predict how that rollout will occur over the next several blogs I publish. In the meantime, a little background:
It turns out that DNSSEC is a lot like CB or ham radio. You have a transmitter, you have receivers. In the case of DNSSEC, you have authoritative DNS servers that sign their data (the transmitters), and caching servers that validate the signatures upon reception (the receivers).
There has been a lot of news lately about ramping up the number of transmitters. The signing of .GOV and .ORG are noteworthy. The secspider at UCLA shows the number of signed zones climbing (http://secspider.cs.ucla.edu/).l
But what about the receivers? Some large organizations like Comcast have set up trial sites (http://www.dnssec.comcast.net/), but I think we're missing a huge opportunity here. The average DNS administrator probably doesn't know jack about setting up DNSSEC.
Can we fix this? Are the DNS servers out there at least sort-of-possibly "ready" to do DNSSEC? The answer is YES. Although this article at networkworld (http://www.networkworld.com/news/2008/111008-dns-server-kaminsky.html?hpg1=bn) writes about how many servers HAVEN'T been patched for the Kaminsky exploit, it's easy to turn it around to see that a huge number of servers have upgraded their DNS. This means there are LOTS of DNS servers out there that are at least capable of doing DNSSEC -- the "receiver" side of the equation.
Now we need to make it "falling off a log easy" for Joe Administrator to actually turn DNSSEC on and set up a safe set of Trust Anchors. If we do that, we complete the circuit. We have transmitters AND receivers. BREAKER BREAKER! (ok,I never did own a CB radio, and I'm lousy at faking the lingo, but what the heck...)
Next blog: ideas on how to get Joe Administrator to actually turn DNSSEC on at sites around the world.
