If your wireless network is not secure, a hacker can easily intercept the data you send and receive, or access files saved on your computer – all from the comfort of their own sofa.

Why is it necessary to secure my wireless network?
These days, most computers are wireless-enabled: they let you connect to the Internet without a physical network cable. The major benefit, of course, is that you can use your computer anywhere in the house or office (as long as it’s within range of your wireless router). However, there are potential risks involved in wireless networking - unless you make your network secure:
• A hacker could intercept any data you send and receive;
• A hacker could get access to your wireless network;
• Another person could hijack your Internet access.

Therefore, if your wireless network is not protected, a hacker could intercept any data you send; access your network, and therefore your shared files; use your connection to connect to the Internet - especially significant if you have a download limit on your internet package and your bandwidth is being swallowed up by a hijacker.

How to secure my wireless network:
• Change the administrator password for your wireless router. It’s easy for a hacker to find out the manufacturer’s default password and use this to access your wireless network. And avoid using a password that can be guessed easily: follow the guidelines provided in the section below on choosing a password.
• Switch off SSID (Service Set Identifier) broadcasting, to prevent your wireless device announcing its presence to the world. Enable encryption in your connection settings: WPA encryption is best, if your device supports it (if not, use WEP encryption).
• Change the default SSID name of your device.

To secure your wireless network:
*Change the administrator password;
*Enable WAP or WEP encryption;
*Switch off the SSID and change the default name of your wireless router;
*Follow the advice above on how to protect from malicious code and hacker attacks.
