11.1.2  What You Need To Know About Wireless
Wireless Security
The following sections introduce different types of wireless security you can set up in the 
wireless network.
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.
