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.
Your computer or networking equipment may already have a firewall installed. If not, firewall software
solutions are available.
NOTE: Under some circumstances a firewall can block access to Internet games, interfere with printer or file
sharing on a network, or block authorized e-mail attachments. To temporarily resolve the problem, disable
the firewall, perform the task that you want to perform, and then reenable the firewall. To permanently
resolve the problem, reconfigure the firewall.
Installing critical security updates
CAUTION: Microsoft® sends out alerts regarding critical updates. To protect the computer from security
breaches and computer viruses, install all critical updates from Microsoft as soon as you receive an alert.
You can choose whether updates are installed automatically. To change the settings, select Start > Control
Panel > System and Security > Windows Update > Change settings, and then follow the on-screen
instructions.

from being mishandled or stolen. To connect a security cable to your computer, follow the device
manufacturer's instructions.
