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.

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 19.

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 install these updates manually or automatically.

To view or change the settings:

1. From the Start screen, type control panel, and then select Control Panel.

‒ or –

From the Windows desktop, right-click the Start button, and then select Control Panel.

2. Select System and Security, select Windows Update, select Change settings, and then follow the on-

screen instructions.

Securing your wireless network

When you set up a WLAN or access an existing WLAN, always enable security features to protect your network

from unauthorized access. WLANs in public areas (hotspots) like coee shops and airports may not provide

any security.

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 Backing up,

restoring, and recovering on page 30.

Using an optional security cable lock

A security cable lock, 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 dierent from the illustration in this section. For

the location of the security cable slot on your computer, see Getting to know your Sprout on page 1.

1. Loop the security cable lock around a secured object.

2. Insert the key (1) into the security cable lock (2).
