Using firewall software

Firewalls are designed to prevent unauthorized access to a system or network. A firewall can be

software you install on your computer and/or network, or it can be a combination of both hardware

and software.

There are two types of firewalls to consider:

●

Host-based firewalls—Software that protects only the computer it is installed on.

●

Network-based firewalls—Installed between your DSL or cable modem and your home network

to protect all the computers on the network.

When a firewall is installed on a system, all data sent to and from the system is monitored and

compared with a set of user-defined security criteria. Any data that does not meet those criteria is

blocked.
