Wireless Security Overview
Wireless security is vital to your network to protect wireless communication
between wireless clients, access points and the wired network.
Wireless security methods available on the NWA are data encryption, wireless
client authentication, restricting access by device MAC address and hiding the
NWA identity.
The following figure shows the relative effectiveness of these wireless security
methods available on your NWA.
Note: You must enable the same wireless security settings on the NWA and on all
wireless clients that you want to associate with it.
