There many RADIUS servers available in the market for free which you can configure on your machine. One of them is FreeRadius- a daemon for Unix and Unix-like operating systems which allows one to set up a radius protocol server- which can be used for authenticating and accounting various types of network access. It helps companies to have the privacy and security of the system and individual users. It provides security and helps companies to maintain a central location for managing client credentials and give easy-to-execute policies that can be applied to a vast range of users from the single administered network point. It is a client-server protocol that enables remote servers (Network Access Server-NAS) to communicate with the central servers (Active Directory) to authenticate and authorize dial-in users (WIFI/wired clients) to provide them access to the requested resources. To implement 802.11X, we need an external server called a Remote Authentication Dial-in User Service (RADIUS) or Authentication, Authorization, and Accounting (AAA) server, which is used for a variety of network protocols and environments including ISPs. It acts as a proxy for the end-user and restricts the end-user’s communication with the authentication server.

RADIUS servers receive user connection requests, authenticate the user, and then return the configuration information required for the client to connect to the Wi-Fi.Ĩ02.1X Authentication comprises of three main parts:ġ ) Supplicant – Supplicant is a client or end-user who is waiting for authenticationĢ) Authentication Server (usually a RADIUS server): This server decides whether to accept the end user’s request for full network access.ģ) Authenticator – It is an access point or a switch that sits between the supplicant and the authentication server.

Whenever a wireless client tries to connect to a WLAN, the client passes user information (username/password) to access point, and these access points carry forward this information to the designated RADIUS server. In a wireless network, 802.1X is used by an access point to authenticate client request to connect to the Wi-Fi. And to achieve this, I had to set up my radius server. Quite recently, I got the opportunity to work on the FreeRadius server for one of the customer requirements to test their product (access points) for the 802.11X standard.
