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.
Installing software updates
HP, Windows, and third-party software installed on your computer should be regularly updated to correct
security problems and improve software performance. For more information, see
Updating programs and
drivers on page 35.
Installing critical security updates

breaches and computer viruses, install all critical updates from Microsoft as soon as you receive an alert.

provide any security.
