How to Make Your Wireless Network More Secure
Wireless networks can be vulnerable to an outsider gaining access if the encryption settings are not set adequately. Some of the default security settings on some wireless hardware, and in Microsoft Windows, may allow access to your wireless network from other wireless devices.
The concepts that are presented here are offered only as a guide, and may help make your wireless network more difficult for an outsider to gain access. For more specific information about the implementation of these suggestions, you should consult a trusted security source.
■Enable Wired Equivalent Privacy (WEP) encryption.
The 802.11 standard, which your NetComm WLAN device is based on, permits Wired Equivalent Privacy (WEP) encryption. Depending on what other hardware you use, there are two levels of WEP typically available:
■Change the default Service Set Identifier (SSID) and passwords for your network devices.
Do not change the SSID or password to reflect your name, address, or anything that would be easy to guess as this could make it easy for an outsider to gain access to your wireless network.
■Install Access Points away from windows or building perimeter.
If you are installing access points, think about locating them towards the centre of your site instead of near the windows. Plan your coverage to radiate out to the windows, but not beyond. If the access points are located near the windows, a stronger signal will be radiated outside your home making it easier for those outside the building to locate your network.
■Check the range of your network.
Take a notebook, or a PDA computer, that is equipped with a wireless network PC Card and go outside your home to survey what range you get when moving around your property or neighbourhood. You may be surprised how far the signal radiates. If you can connect beyond the perimeter of your property, so can someone else.
■Disable the Beacon.
If possible, disabling the beacon will make it harder for hackers to locate and identify your network.
■Use a combination of the previous suggestions.
