RADIUS, which stands for "Remote Authentication Dial In User Service", is a network protocol - a system that defines rules and conventions for communication between network devices - for remote user authentication and accounting. Commonly used by Internet Service Providers (ISPs), cellular network providers, and corporate and educational networks, the RADIUS protocol serves three primary functions:

* Authenticates users or devices before allowing them access to a network * Authorizes those users or devices for specific network services * Accounts for and tracks the usage of those services

FreeRADIUS is a modular open-source implementation of the RADIUS protocol featuring numerous authentication types, including Extensible Authentication Protocol (EAP), support for virtual servers and more.
