RADIUS
Remote Authentication Dial In User Service (RADIUS) is an
AAA (authentication, authorization and accounting) protocol for applications such as network access or IP mobility. It is intended to work in both local and
roaming situations.Many networks services (including corporate networks and public
ISPs using modem, DSL, or wireless 802.11 technologies) require you to present security credentials (such as a
username and
password or security certificate) in order to connect on to the network. Before access to the network is granted, this information is passed to a
Network Access Server (NAS) device over the link-layer protocol (for example,
Point-to-Point Protocol (PPP) in the case of many dialup or DSL providers), then to a RADIUS server over the RADIUS protocol. The RADIUS server checks that the information is correct using authentication schemes like
PAP,
CHAP or
EAP. If accepted, the server will then indicate to the NAS that you are authorized to access the network. RADIUS also allows the authentication server to supply the NAS with additional parameters, such asThe specific
IP address to be assigned to the userThe address pool from which the user's IP should be chosenThe maximum length that the user may remain connectedAn access list, priority queue or other restrictions on a user's access
L2TP parameters

Radius (informatique)
RADIUS (Remote Authentication Dial-In User Service) est un
protocole client-serveur permettant de centraliser des données d'
authentification. En français on préfère souvent parler d'identification pour traduire l'anglais authentication, car l'identification effectuée par un serveur Radius est une vérification de nom d'utilisateur (attribut 1 User-Name) et de mot de passe (attribut 2 User-Password ou 3 Chap-Password). L'authentification en français est définie comme la vérification approfondie par un expert ou un officier ministériel et correspond à l'anglicisme authentification forte pour "strong authentication", mais l'abus de langage est courant.

Radius
Als Radius (von lat. radius; „Strahl“) (deutsch: Halbmesser) bezeichnet man in der Geometrie den Abstand zwischen dem
Mittelpunkt M eines
Kreises und der Kreislinie. Analog dazu heißt auch bei der
Kugel der Abstand zwischen Mittelpunkt und Kugelfläche so. Verallgemeinert besitzt jedes geometrische Objekt mit einem kreisförmigen
Querschnitt oder einer kreisförmigen
Grundfläche einen Radius, also auch ein
Zylinder oder ein
Kegel.

RADIUS
RADIUS (
ang. Remote Authentication Dial In User Service), usługa zdalnego uwierzytelniania użytkowników, którzy wdzwaniają się do systemu (poprzez usługę "
połączenia dodzwaniane"). Protokół używany do uwierzytelniania. Stosowany przez dostawców internetowych na serwerach innych niż serwery z systemem Windows. Obecnie jest najpopularniejszym protokołem podczas uwierzytelniania i autoryzowania użytkowników sieci telefonicznych i tunelowych.

RADIUS
RADIUS (Remote Authentication Dial-In User Service) è un
protocollo AAA (authentication, authorization, accounting) utilizzato in applicazioni di accesso alle reti o di mobilità
IP. RADIUS è attualmente lo standard de-facto per l’autenticazione remota, prevalendo sia nei sistemi nuovi che in quelli già esistenti.
