A firewall is a protective system that mediates between your computer network and the internet. When used correctly, a firewall prevents unauthorized use and access to your network.

Firewalls and routers work by screening information coming from and going to the Internet. They identify and ignore information that comes from a dangerous or unreliable location or seems uncertain. If you set up your firewall properly, hackers searching for vulnerable computers cannot detect your computer.

Firewalls can be either hardware or software:

• Software firewalls can be installed on individual PCs to offer basic defense from outside and
  inside attacks.
• Networking software firewalls can be installed to protect an entire network of PCs.
• An in-modem attaches to your PC and offers “built-in” firewall features.
• Hardware routers sit between your modem and your computer to provide an additional outer layer
  of defense. These can be “wired” or “wireless. Wireless routers can be connected to your PC and
  are actually wired routers with wireless access points built in so you can have wired and/or
  wireless at the same time.
