Web Stalkers
Chapter 9 - Self Protection on the Web

Hardware Firewalls

A hardware firewall is a separate piece of equipment.  This type of firewall is sometimes integrated into a wireless hub or access point.  Other times it is a self-contained unit, much like a DSL or cable modem.  It will generally be installed between the DSL or cable modem and the computer, hub, or wireless gateway.

Technically adept folks can use an older computer and install a second network card and free software to create a robust firewall. One of the advantages of hardware firewalls is that one can be properly positioned to protect multiple computers.  This can be advantageous for a home user with more than one computer.

A downside to hardware firewalls is that there is a new piece of computer equipment for the user to deal with.  That means another product competing for an electrical connection in the already crowded computer area.

Software Firewalls

A software firewall is simply a program that runs on a computer that performs the same functions as a hardware firewall.  It takes advantage of the computer’s ability to do more than one job at a time.  This is called multi-tasking.  The software firewall process causes the computer to work more than it is usually required to as it simply keeps up with the human’s limited requirements.
