As we all move to dedicated Internet access, security has become a concern for most everyone. Firewalls are becoming more necessary to make sure that the information on your computer is safe.

There are 2 ways of securing your system.

1. Software based firewalls
   This type of firewall runs on your computer and can be set for several levels of security. See the below links for more information:

2. Hardware Firewalls.
   This type of security is a physical device that sits infront of your system or network. They tend to be more robust and configurable than the software based solutions. They are also much more expensive. Prices usually range between $100 - $10,000 depending on the features. Hardware solutions (routers) are usually better suited for the home network and small business. See the below links for more information.
