Introduction
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.
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 802.1x with a RADIUS
(Remote Authentication Dial-in User Service) server, a network adminstrator 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).
