How Long is Too Long to Update?
StWaldo asks: "I'm sure everyone knows the story about the life expectancy of an fresh, un-updated PC, once it's connected to the internet. What about a PC which just hasn't been updated in a while? I've been deployed in Iraq for the last 9 months, and haven't been able to hook up my laptop to the internet to get updates (I do HAVE access, just can't hook up a personal laptop, gov't only). Before I deployed, I would update my software (system, anti-virus, firewall, anti-spyware, etc) regularly, but as I get closer to coming back to the States and my broadband connection, I'm beginning to wonder what the life expectancy of my PC will be. What's the lifecycle of a security exploit, hack, virus, etc - between discovery/release, propagation, and extinction (or a state approaching extinction)?"
My wireless router logged connection attempts at a rate of around one every 10 seconds when I was on a DSL line. I'm on cable now, and get fewer attempts - just every couple of minutes.
Not all of those attempts are trying to break in to Windows vulnerabilities, a lot were looking for other kinds of holes, or were looking for already-infected machines. But the attempt I see logged from one minute ago was attempting to get into the Windows RPC service, which an unpatched machine might have left open.
So I don't really think it's paranoia, and I do like being the only machine behind my router.
