Introduction (continued)
WPA-Enterprise and WPA2-Enterprise is ideal for businesses that have existing security
infrastructures in place. Management and security implementation can now be centralized on
a server participating on the network. Utilizing 80.1x with a RADIUS (Remote Authentication
Dial-in User Service) server, a network administrator can define a list of authorized users who
can access the wireless LAN. When attempting to access a wireless LAN with either WPA-
Enterprise or WPA2-Enterprise configured, the new client will be challenged with a username and
password. If the new client is authorized by the administration, and enters the correct username
and password, then access is granted. In a scenario where an employee leaves the company, the
network administrator can remove the employee from the authorized list and not have to worry
about the network being compromised by a former employee. WPA2-Enterprise is far superior
to WPA-Enterprise, because the encryption of data is upgraded with the Advanced Encryption
Standard (AES).
802.1x: Authentication which is a first line of defense against intrusion. In the authentication
process, the Authentication Server verifies the identity of the client attempting to connect to the
network. Unfamiliar clients would be denied access.
EAP (Extensible Authentication Protocol) is available through the Windows XP Operating System.
You will need to use the same type of EAP protocol on all the devices in your network when using
the 80.1x feature.
