Explanation:
A central authentication service for dial-up users is the standard Remote Authentication and Dial-In User
Service (RADIUS). RADIUS incorporates an authentication server and dynamic passwords. The RADIUS
protocol is an open lightweight, UDP-based protocol that can be modified to work with a variety of security
systems. It provides authentication, authorization and accounting services to routers, modem servers, and
wireless applications. RADIUS is described in RFC 2865.
