DMZ and Securing your Web Server

What are DMZ’s and how can they contribute to securing your web server?

A DMZ is a 'Demilitarized Zone'. Its just an area outside your firewall, like the front yard of your house. It belongs to you and you may put some things there, but you would put anything valuable inside the house where it can be properly secured.
Most software firewalls available will allow you to designate a directory on the computer as a DMZ if you have multiple computers on your network.
Once you have a firewall in place, you should test it.
A great way to do this is to go to www.grc.com and try their free Shields Up! security test.
