Internet Firewalls seem to be in style in recent times. For those unfamiliar with what a firewall is, It pretty much is a program that sits between you and the outside world- think of a toll booth that stands at the borderline between your world and the digital world. There are many different brands of firewalls from companies like Linksys, D-Link, Netgear, and many others. Actually if you are familiar with Windows XP, there is a built in firewall program that you can use to supply a basic protection between you and your network. If you prefer more comprehensive solutions you can do a search for free firewall programs on the net or purchase one. It's billed as the one-stop solution to prevent hackers and unauthorized access by intruders (both human and program generated). However firewalls are not impregnable.

There are online testing services that are either free or charge a nominal fee that will help you check to see if your firewall is working or not, or whether it has been compromised. You may have also found that a firewall will not always operate nicely with your other programs, such as antivirus and anti spyware related software. This usually can be adjusted within the firewall program, where you can configure which programs and services on your computer are allowed to travel back and forth between you and the network.
