To demonstrate how corporations and ISPs can use Internet Connection Services for RAS to administer heterogeneous collections of Network Access Servers, this section uses a fictitious company named Humongous Insurance (HI). HI is a large company that sells all types of insurance to both consumers and corporate clients. Using dedicated lines and large modem pools, Humongous Insurance offered its employees remote access to the corporate network.
Humongous Insurance used Network Access Servers (NAS) from a variety of vendors, including Microsoft Remote Access Servers (RAS). Since HI is administering a heterogeneous network of NAS devices, they wish to use the Remote Authentication Dial-In User Service (RADIUS) to provide unified administration across their multi-vendor network. Since HI wishes to maintain a single, unified user database, they store their user information in the Windows NT Server directory.
Since HI is concerned about dial-up security, they wish to ensure that all data transmitted over the phone lines is encrypted and that access is provided using encrypted authentication. For this reason HI chose to support Microsoft Challenge Handshake Authentication Protocol (MS-CHAP).
