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.
- Secure your wireless router or access point administration interface
- Don't broadcast your SSID
- Enable WPA encryption instead of WEP
- Remember that WEP is better than nothing
- Use MAC filtering for access control
- Reduce your WLAN transmitter power
- 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.
