8021X-Overview
A client (1) needs to be authenticated before it can access a resource (3).

IEEE 802.1 is the name for a number of high-level protocols for computer networks. In this context, IEEE 802.1X helps secure such a network. It defines methods to authenticate devices and to authorise the access to certain resources. A dedicated server checks information received from a "supplicant". Depending on the result of the check, access to the given resource is granted or denied.
