Using rewall software

Firewalls are designed to prevent unauthorized access to a system or network. A rewall can be a software

program you install on your tablet and/or network, 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 tablet it is installed on.

●

Network-based rewalls—Installed between your DSL or cable modem and your home network to

protect all devices 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.

Windows Defender is installed on your tablet.

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 permanently resolve the problem,

recongure the rewall. To temporarily resolve the problem, disable the rewall, perform the task that you

want to perform, and then reenable the rewall.

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 choose whether updates are installed automatically.

To change the settings:

Windows 10

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.

Windows 8

1. On the Start screen, swipe from the right side of the screen, tap Settings, and then tap Control Panel.

2. Tap System and Security, tap Windows Update, tap Change settings, and then follow the on-screen

instructions.

Using HP Client Security

HP Client Security software is preinstalled on your tablet. This software can be accessed through the HP Client

Security tile on the Start screen; the icon on the Windows desktop in the notication area, at the far right of

the taskbar; or Windows Control Panel. It provides security features that help protect against unauthorized

access to the tablet, networks, and critical data. For more information, see the HP Client Security software

Help.
