							10 Securing your computer and
information
Computer security is essential for protecting the confidentiality, integrity, and availability of your
information. Standard security solutions provided by the Windows® operating system, HP
applications, the non–Windows Setup Utility (BIOS), and other third-party software can help protect
your computer from a variety of risks, such as viruses, worms, and other types of malicious code.
IMPORTANT:Some security features listed in this chapter may not be available on your computer.

Using passwords
A password is a group of characters that you choose to secure your computer information and to
have safer online transactions. Several types of passwords can be set. For example, when you set up
your computer for the first time, you were asked to set up a user password to secure your computer.
Additional passwords can be set in Windows or in the HP Setup Utility (BIOS) that is preinstalled on
your computer.
You may find it helpful to use the same password for a Setup Utility (BIOS) feature and for a Windows
security feature.
Use the following tips for creating and saving passwords:
●To reduce the risk of being locked out of the computer, record each password and store it in a
secure place away from the computer. Do not store passwords in a file on the computer.
●When creating passwords, follow requirements set by the program.
●Change your passwords at least every three months.
●An ideal password is long and has letters, punctuation, symbols, and numbers.
●Before you send your computer for service, back up your files, delete confidential files, and then
remove all password settings.
For additional information about Windows passwords, such as screen-saver passwords, select Start
> Help and Support.

							Using the fingerprint reader
Integrated fingerprint readers are available on select computer models. In order to use the fingerprint
reader, you must set up a user account and password on the computer. This account allows you to
log on to your computer with a swipe of a designated finger. You may also use the fingerprint reader
to fill in password fields on Web sites and other programs that require a logon. For instructions, see
the fingerprint reader software Help.
After you register your computer, you can set up a single sign-on service that allows you to use your
fingerprint reader to create credentials for any application that requires a user name and password.
For the location of the fingerprint reader on your computer, see “Getting to know your computer.”
Registering fingerprints
A Fingerprint Reader allows you to log on to Windows using a fingerprint that you have registered
using HP SimplePass software, instead of using a Windows password.
To register one or more fingerprints:
1.Select Start > Security and Protection > HP SimplePass.
2.Have you found your fingerprint sensor?—Click Yes.
3.Are you ready to enroll?—Click Yes.
4.Select a finger.
5.Create Windows password—Enter your password and confirm your password.
6.Swipe your finger 3 times. The finger displays green if it is registered successfully. Otherwise, a
warning message is displayed.
7.Select another finger or click > to continue.

							Using Internet security software
When you use your computer to access email, a network, or the Internet, you potentially expose your
computer to computer viruses, spyware, and other online threats. To help protect your computer,
Internet security software that includes antivirus and firewall features may be preinstalled on your
computer as a trial offer. To provide ongoing protection against newly discovered viruses and other
security risks, security software must be kept up to date. It is strongly recommended that you upgrade
the security software trial offer or purchase the software of your choice in order to fully protect your
computer.
Using antivirus software
Computer viruses can disable programs, utilities, or the operating system, or cause them to function
abnormally. Antivirus software can detect most viruses, destroy them, and in most cases, repair any
damage they have caused.
For more information about computer viruses, type viruses in the Search box in Help and Support.
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, Microsoft Windows, and third-party software installed on your computer should be regularly
updated to correct security problems and improve software performance.
Installing Windows security updates
Updates to the operating system and other software may have become available after the computer
left the factory. 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.
To be sure that all available updates are installed on the computer, observe these guidelines:
●Run Windows Update as soon as possible after you set up your computer. Select Start > All
Programs > Windows Update.
●Run Windows Update monthly thereafter.
●Obtain updates to Windows and other Microsoft programs, as they are released, from the
Microsoft website and through the updates link in Help and Support.
Installing HP and third-party software updates
HP recommends that you regularly update the software and drivers that were originally installed on
your computer. To download the latest versions, go to 
http://www.hp.com/support. At this location,
you can also register to receive automatic update notifications when they become available.
If you have installed third-party software after you purchased your computer, regularly update the
software. Software companies provide software updates to their products to correct security problems
and improve functionality of the software.
Securing your wireless network
When you set up your wireless network, always enable security features. For more information, see
“Protecting your WLAN” in the Networking chapter.
Installing software updates 79 
						

							Backing up your software applications and information
Regularly back up your software applications and information to protect them from being permanently
lost or damaged through a virus attack or a software or hardware failure. For more information, see
“Backup and recovery.”
Using an optional security cable lock
A security cable lock, which is purchased separately, is designed to act as a deterrent, but it may not
prevent the computer from being mishandled or stolen. Security cable locks are only one of several
methods that should be employed as part of a complete security solution to help maximize theft
protection.
The security cable slot on your computer may look slightly different from the illustration in this section.
For the location of the security cable slot on your computer, see “Getting to know your computer.”
1.Loop the security cable lock around a secured object.
2.Insert the key (1) into the security cable lock (2).
3.Insert the security cable lock into the security cable slot on the computer (3), and then lock the
security cable lock with the key.
4.Remove the key and keep it in a safe place.
