15. ADIUS solves these issues by centralizing security and accounting information This improves security and provides a solution that can adapt to the changing size and needs of remote users and service providers How RADIUS Works A RADIUS application has two components the RADIUS server and the RADIUS client The RADIUS server is a computer equipped with server software for example a UNIX workstation that is located at a central office or campus It has authentication and access information in a form that is compatible with the client A network can have one server for both authentication and accounting or one server for each service The RADIUS client can be a router or a remote access server that is equipped with client software and typically resides on the same local area network LAN segment as the server The client is the network access point between the remote users and the server 303538 A Rev 00 2 1 Configuring RADIUS RADIUS authentication lets you identify remote users before you give them access to a central network site RADIUS accounting enables the server to collect data during a remote user s dial in session with the client The server can then determine billing charges Figure 2 1 shows a sample network using RADIUS RADIUS server BLN RADIUS client Remote dial in B
