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 32. Installing critical security updates CAUTION: Microsoft sends out alerts regarding critical updates.
