Installing Software Updates - HP Sprout User Manual

● 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, 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
drivers on page

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
restoring, and recovering on page
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 different from the illustration in this section. For
the location of the security cable slot on your computer, see
1. Loop the security cable lock around a secured object.
2. Insert the key (1) into the security cable lock (2).
