Security Settings for WPA, WPA2
When WPA or WPA2 is used for authentication, you will also need to configure EAP method in
the Security settings for the WLAN profile. Other settings will also be displayed depending on
how EAP method is configured.
There are two parts to WPA and WPA2 security, authentication and data encryption.
y Authentication occurs before access is granted to a WLAN. Wireless clients such as the
NPort W2150/2250 Plus Series are first authenticated by the AP according to the
authentication protocol used by the RADIUS server. Depending on the WLAN security
settings, an EAP tunnel can be used to scramble the username and password that is
submitted for authentication purposes.
y Encryption occurs after WLAN access has been granted. For all wireless devices, data is
first encrypted before wireless transmission, using mutually agreed-upon encryption
protocol.
