802.1X
authentication is a network security method that ensures only
authorized devices or users can access a network by verifying their
identity before granting access. It prevents unauthorized access and
enhances network security.

✓Supplicant (Employee's Device): Your company laptop (supplicant) attempts to connect to the corporate Wi-Fi network.
✓Authenticator
(Wi-Fi Access Point): The Wi-Fi access point (authenticator) receives
the connection request from your laptop and asks for your identity.
✓Supplicant (Employee's Device): Your laptop responds with your corporate username.
✓Authenticator (Wi-Fi Access Point): The Wi-Fi access point forwards your username to the authentication server.
✓Authentication
Server (Server at Your Company): The company's authentication server
receives your username and determines the appropriate authentication
method based on its policy. Let's say it selects EAP-TLS, a strong
method that uses digital certificates.
✓Supplicant (Employee's
Device) and Authentication Server: Your laptop and the authentication
server engage in an EAP-TLS handshake, where your laptop presents its
digital certificate and proves its identity to the server.
✓Authentication
Server (Server at Your Company): The authentication server verifies the
digital certificate and, upon successful authentication, informs the
Wi-Fi access point.
✓Authenticator (Wi-Fi Access Point): The
access point, after receiving confirmation from the authentication
server, allows your laptop to connect to the corporate Wi-Fi network. If
authentication fails, the supplicant is denied access to the network.
In
this real-world scenario, 802.1X EAP authentication ensures that only
authorized employees with the necessary digital certificates can access
the corporate network. It offers a robust and secure way to control
network access, protecting sensitive company data and resources.
