These days wireless networking products are so ubiquitous and inexpensive that just about anyone can set up a WLAN in a matter of minutes with less than $100 worth of equipment. This widespread use of wireless networks means that there may be dozens of potential network intruders lurking within range of your home or office WLAN.

1) Secure your wireless router or access point administration interface

2) Don't broadcast your SSID

3) Enable WPA encryption instead of WEP

4) Remember that WEP is better than nothing

5) Use MAC filtering for access control

6) Reduce your WLAN transmitter power

7) Disable remote administration

Today's Wi-Fi networking products don't always help the situation as configuring their security features can be time-consuming and non-intuitive. WPA is a security technology for Wi-Fi wireless computer networks. WPA improves on the authentication and encryption features of WEP (Wired Equivalent Privacy). A variation of WPA designed for use on home networks is called WPA Pre Shared Key or WPA-PSK for short. WPA-PSK is a simplified but still powerful form of WPA.
