How does Radius Authentication Work Take Place?

Radius is a  framework of networking protocol that delivers centralized Authentication, Authorization, and Accounting (AAA) management for users to attach and operate a network service. The actual process of how Radius Authentication works is relatively simple and involves the communication between a server and a client.

In most cases, the server is a networking device like a router responsible for connecting to a network and controlling all access. The server will store and maintain a list of all users allowed to connect to the network and their associated credentials. When a user attempts to connect to the network, the server will authenticate and authorize the user before allowing them to access the network resources.

The client in this process is typically a Radio server client attempting to connect to a network. First, the client will ask the server to establish and permit the user. The server will then either allow or deny the user access to the network.

Radius Authentication is a simple and effective way to control access to a network. It is often utilized with other security measures like firewalls to deliver a supplementary layer of security.

A networking protocol is a set of rules that governs the communication between two networked devices. There are many different types of networking protocols, but one of the most common is the client server communication approach. In a client server communication approach, one device, the server, is responsible for storing and maintaining information, while the other, the client, is responsible for connecting to the network and authenticating with the server. The client server communication approach is very common, and is used in many different networking devices, like routers, which connect networks together.

The server will then authenticate and allow the user access to the network. The client server communication approach is a very secure way to control all access to a network, and is used in many different applications, like secure authentication systems.

What is Free radius used for? 

The freeradius server comes with a PHP-based web user administration interface. It also supports multiple databases so you can use different database backends for various tasks.

It is a very feature-rich server and supports many authentication methods. It can be used for PPP authentication, as well as for 802.1X/EAP authentication. It also supports many other features, such as accounting, session limits, concurrency limits, etc.

If you are looking for a RADIUS server that is easy to use and configure, then FreeRADIUS is the best option for you.
