Remote Authentication Dial-In User Service (RADIUS) is a networking protocol that provides centralized authentication, authorization, and accounting (AAA) management for users who connect and use a network service. RADIUS was developed by Livingston Enterprises in 1991 as an access server authentication and accounting protocol. It was later brought into IEEE 802 and IETF standards.
RADIUS is a client/server protocol that runs in the application layer, and can use either TCP or UDP. Network access servers, which control access to a network, usually contain a RADIUS client component that communicates with the RADIUS server.[1] RADIUS is often the back-end of choice for 802.1X authentication.[2] A RADIUS server is usually a background process running on UNIX or Microsoft Windows.[1]
The Blast-RADIUS attack breaks RADIUS when it is run on an unencrypted transport protocol like UDP.[3]
