Using firewall software

Firewalls are designed to prevent unauthorized access to a system or network. A firewall can be

software you install on your tablet 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 tablet 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 tablet should be regularly updated to correct

security problems and improve software performance. For more information, see Updating programs

and drivers on page 17.

Installing critical security updates

CAUTION: Microsoft sends out alerts regarding critical updates. To protect the tablet 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:

From the Start screen, tap , type 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 coffee 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

Backup and recovery on page 25.
