Using rewall software
Firewalls are designed to prevent unauthorized access to a system or network. A rewall can be a software
program that you install on your computer, network, or both, or it can be a solution made up of both
hardware and software.
There are two types of rewalls to consider:
Host-based rewalls—Software that protects only the computer it is installed on.
Network-based rewalls—Installed between your DSL or cable modem and your home network to
protect all the computers on the network.
When a rewall is installed on a system, all data sent to and from the system is monitored and compared with
a set of user-dened security criteria. Any data that does not meet those criteria is blocked.
Your computer or networking equipment may already have a rewall installed. If not, rewall software
solutions are available.
NOTE: Under some circumstances a rewall can block access to internet games, interfere with printer or le
sharing on a network, or block authorized email attachments. To temporarily resolve the problem, disable the
rewall, perform the task that you want to perform, and then reenable the rewall. To permanently resolve
the problem, recongure the rewall.
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.
To view or change the settings:
IMPORTANT: Microsoft sends out alerts regarding Windows updates, which may include security updates.
To protect the computer from security breaches and computer viruses, install all updates from Microsoft as
soon as you receive an alert.
You can install these updates automatically.
1. Select the Start button, select Settings, and then select Update & Security.
2. Select Windows Update, and then follow the on-screen instructions.
3. To schedule a time for installing updates, select Advanced Options, and then follow the on-screen
instructions.
