1.5M DB Servers Have No Firewall

I saw this article this morning and my jaw hit the ground. The gist of it is David Litchfield, managing director or NGSSoftware, has concluded there are roughly 1.5M database servers accessible from the Internet with no firewall. Furthermore a great number of these are un-patched. This is scary stuff. I don't get overly concerned with privacy but I do get concerned when my personal data may be easily accessible due to negligence. Just because you can find the power button on a computer and you can install software doesn't make you an IT person any more than knowing how to open the aspirin bottle and apply a Band-Aid makes you a doctor. *sigh*
