• Every wireless client in the same wireless network must use security compatible with the
AP.
Security stops unauthorized devices from using the wireless network. It can also protect
the information that is sent in the wireless network.
7.2 Wireless Security Overview
The following table shows the relative strengths of common types of wireless security. Use the
strongest security that every wireless client in the wireless network supports.
If you have a RADIUS server, you can use WPA or WPA2 so users have to log into the
wireless network before using it. This is called user authentication. RADIUS servers are more
common in businesses (WPA and WPA2 are also called the enterprise version of WPA).
If you do not have a RADIUS server, the strongest wireless security you can use is WPA2-
PSK (WPA2-PSK and WPA-PSK are also known as the personal version of WPA).
"
It is recommended that wireless networks use WPA-PSK, WPA, or stronger
security. WEP is better than no security, but it is still possible for unauthorized
devices to figure out the original information pretty quickly.
When you select
WPA2
or
WPA2-PSK
in your ZyXEL Device, you can also select an option
(
WPA Compatible
) to support WPA as well. In this case, if some wireless clients support
WPA and some support WPA2, you should set up
WPA2-PSK
or
WPA2
(depending on the
type of wireless network login) and select the
WPA Compatible
option in the ZyXEL Device.
7.2.1 SSID
Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can
hide the SSID instead, in which case the AP does not broadcast the SSID. In addition, you
should change the default SSID to something that is difficult to guess.
This type of security is fairly weak, however, because there are ways for unauthorized devices
to get the SSID. In addition, unauthorized devices can still see the information that is sent in
the wireless network.
