Product Description
Product Description
The subject of security never strays far from the minds of IT workers, for good reason. If there is a network with even just one connection to another network, it needs to be secured. RADIUS, or Remote Authentication Dial-In User Service, is a widely deployed protocol that enables companies to authenticate, authorize and account for remote users who want access to a system or service from a central network server. Originally developed for dial-up remote access, RADIUS is now used by virtual private network (VPN) servers, wireless access points, authenticating Ethernet switches, Digital Subscriber Line (DSL) access, and other network access types. Extensible, easy to implement, supported, and actively developed, RADIUS is currently the de facto standard for remote authentication.
RADIUS provides a complete, detailed guide to the underpinnings of the RADIUS protocol, with particular emphasis on the utility of user accounting. Author Jonathan Hassell draws from his extensive experience in Internet service provider operations to bring practical suggestions and advice for implementing RADIUS. He also provides instructions for using an open-source variation called FreeRADIUS.
"RADIUS is an extensible protocol that enjoys the support of a wide range of vendors," says Jonathan Hassell. "Coupled with the amazing efforts of the open source development community to extend RADIUS's capabilities to other applications-Web, calling card security, physical device security, such as RSA's SecureID-RADIUS is possibly the best protocol with which to ensure only the people that need access to a resource indeed gain that access."
This unique book covers RADIUS completely, from the history and theory of the architecture around which it was designed, to how the protocol and its ancillaries function on a day-to-day basis, to implementing RADIUS-based security in a variety of corporate and service provider environments. If you are an ISP owner or administrator, corporate IT professional responsible for maintaining mobile user connectivity, or a web presence provider responsible for providing multiple communications resources, you'll want this book to help you master this widely implemented but little understood protocol.

Common problems are covered and links to a suitable test tool is very much welcome.
It is not a daunting book to read and is a worthy addition to the other Orielly books range.
Am I glad I ordered it from Amazon?
You bet.

The RFCs tend to be full of nitty gritty legalese, by the very nature of their being formal specifications. That is the reason one would want to read a book, such as this one, in the hope of gaining implementation and deployment perspective that may be lacking in the the RFCs. This book does not measure up.
It is poorly organized, is ridden with glaring errors, and does not explain key concepts well, if at all. If the author has brought any technical expertise on the subject matter to bear, it certainly does not show up. It looks and feels like a potpourri of hastily put together notes by a sysadmin technician; nothing more.
