802.1x Wi-Fi authentication is an effective security protocol that provides additional protection for wireless networks. Requiring users to provide valid credentials before they can connect to the network helps prevent unauthorized access and protects sensitive data. While it may require more effort to set up and manage than other security protocols, the benefits of Wi-Fi authentication make it a worthwhile investment for organizations looking to enhance their network security.
In the context of it, the RADIUS server is responsible for verifying the supplicant’s credentials (the device trying to connect to the network). When a supplicant tries to connect to a network using authentication, the authenticator (such as a wireless access point) sends a request to the RADIUS server for authentication. The Radius authentication server then sends a request for credentials to the supplicant. If the credentials are valid, the RADIUS server sends an access-accept message to the authenticator, allowing the supplicant to access the network.
