Safe use of WLAN base stations
It is difficult to limit the coverage area of a WLAN. For example, at home, the network may extend to the neighbour's apartment and at offices beyond the company premises.
To ensure information security in wireless local area networks, it is essential to take the following steps:
- Define identification settings for the WLAN (e.g. set a password). Without user identification, anyone within the coverage area of the wireless base station can connect to the WLAN.
- Encrypt the traffic transmitted in the WLAN. It is easy to listen in on unencrypted network traffic.
To encrypt WLAN traffic, you should use at least the WEP (Wired Equivalent Privacy) protocol. It is recommendable to use the newer WPA2 (Wi-Fi Protected Access) protocol if the devices and software support it. Detailed instructions on how to enable security features are available in the hardware and software manufacturers' instruction manuals.
In wireless networks, passwords are used in user identification and logging in to the base station control panel. You should change the default password of the control panel of your wireless base station when you start using the device.
