Overview: High-performance, open networking 25GbE top-of-rack and 100GbE spine/leaf switches Dell EMC Networking Virtual Edge Platform 1405.Wyse WSM Desktop & Application Virtualization.In this example, we’ll look a wireless client (e.g., Laptop) that connects to a UniFi AP broadcasting a WPA-Enterprise WLAN, before being authenticated at the RADIUS Server running on the UniFi Security Gateway.īecause the Supplicant and Authentication Server technically use separate protocols for 802.1X authentication (EAP and RADIUS, respectively), it can help to consider the Authenticator as a trusted middle-man who translates messages between Client and Server via encapsulation.įigure F - End-to-end process shown for 802.1X, an authentication framework defining Port-Based Network Access Control.

Enterprise networks and ISPs often install RADIUS software (e.g., FreeRADIUS) on a server machine to act as the Authentication Server.Īs of v5.6.x, the UniFi Security Gateway supports a built-in RADIUS Server, as well as configured RADIUS Users for local authentication.įor integration with external authentication databases, such as MySQL, LDAP, Active Directory, and more, Ubiquiti recommends FreeRADIUS (free RADIUS software that can run on any server-based OS).įigure D - Create a RADIUS Server in the UniFi Network application for Enterprise AAA.įigure E - Add Users to the UniFi Network application for RADIUS-based authentication.įor reference, let’s examine the Client-Server process by which a Supplicant authenticates with the Authentication Server by means of the Authenticator. The Remote Authentication Dial-In User Service (RADIUS) is an AAA protocol that uses UDP Port 1812 to establish connections. Note - Using WPA-Enterprise Security, UniFi APs can be configured as Authenticators within the 802.1X framework.įigure B - Choose WPA-Enterprise for AAA with UniFi Wireless LANs.įigure C - Configure RADIUS Profiles in the UniFi Network application to set up UniFi APs as 802.1X Authenticators. The Supplicant authentication data (EAP) is encapsulated first where at the Authenticator, the data is re-encapsulated using another protocol such as RADIUS to determine the validity of the Supplicant’s provided credentials against the Authentication Server.
Authentication Server, is the device that authenticates the Supplicant.įigure A - Example devices involved in 802.1X framework for AAA controls in secure, Enterprise-grade networks.Authenticator, or the device responsible for initiating the process by which the Supplicant is authenticated.Supplicant, or the device requiring authentication.While many variants of EAP exist (ex., EAP-TLS, EAP-MSCHAPv2), EAP defines the format for messages sent between three parties: Specifically, 802.1X defines Port-Based Network Access Control, a security concept permitting device(s) to authenticate to the network using an encapsulation protocol known as Extensible Authentication Protocol (EAP). Therefore, “802.1X” (not 802.11X) falls under the IEEE standards for LANs. While 802.11 refers to wireless LAN protocols and standards, 802.1 refers to general concepts relating to LANs/WANs, including security, bridging, and more. To begin, 802 refers to the IEEE standards for networking protocols. Accounting means tracking user activity on the network.Authorization means granting user access to particular services / network areas.Authentication means allowing users to join and access the network.
