Network switches can provide open and easy access to network resources
by simply attaching a client PC. Although this automatic configuration and
access is a desirable feature, it also allows unauthorized personnel to easily
intrude and possibly gain access to sensitive network data.
The IEEE 802.1X (dot1x) standard defines a port-based access control
procedure that prevents unauthorized access to a network by requiring
users to first submit credentials for authentication. Access to all switch
ports in a network can be centrally controlled from a server, which means
that authorized users can use the same credentials for authentication from
any point within the network.
