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.
