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 on page 18.
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 59.
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 
on page 5.
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.
