Network Authentication Protocols
Modern networks typically require that users authenticate before gaining access via both wired and wireless connections. The 802.1x protocol provides a framework for implementing authentication on a network. In 802.1x networks, there are three different roles held by components:
- The supplicant is the software running on the client that wishes to connect to the network.
- The authenticator is the network device that the client wishes to connect to, typically an Ethernet switch or a wireless access point.
- The authentication server is the server that validates requests for network access, using the RADIUS or EAP protocols.
We’ve already discussed RADIUS in this chapter, so let’s move on and discuss EAP.
