Remote Authentication Dial-In User Radius (RADIUS) 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. This text is a detailed guide to the underpinnings of 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. This 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 protoc

Most applications these days are at least somewhat network aware, but how do you protect those applications against common network security threats? Many developers are turning to OpenSSL, an open source version of SSL/TLS, which is the most widely used protocol for secure network communications. The OpenSSL library is seeing widespread adoption for web sites that require cryptographic functions to protect a broad range of sensitive information, such as credit card numbers and other financial transactions. The library is the only free, full-featured SSL implementation for C and C++, and it can be used programmatically or from the command line to secure most TCP-based network protocols. Network Security with OpenSSL enables developers to use this protocol much more effectively. Traditionally, getting something simple done in OpenSSL could easily take weeks. This concise book gives you the guidance you need to avoid pitfalls, while allowing you to take advantage of the library?s advanced features. And, instead of bogging you down in the technical details of how SSL works under the hood, this book provides only the information that is necessary to use OpenSSL safely and effectively. In step-by-step fashion, the book details the challenges in securing network communications, and shows you how to use OpenSSL tools to best meet those challenges. As a system or network administrator, you will benefit from the thorough treatment of the OpenSSL command-line interface, as well as from step-by-step directions for obtaining certificates and setting up your own certification authority. As a developer, you will further benefit from the in-depth discussions and examples of how to use OpenSSL in your own programs. Although OpenSSL is written in C, information on how to use OpenSSL with Perl, Python and PHP is also included. OpenSSL may well answer your need to protect sensitive data. If that?s the case, Network Security with OpenSSL is the only guide available on the subject.

This concise guide offers the basic concepts of IP routing, free of hype and jargon. It begins with the simplest routing protocol, RIP, and then proceeds, in order of complexity, to IGRP, EIGRP, RIP2, OSPF, and finally to BGP. New concepts are presented one at a time in successive chapters. By the end, you will have mastered not only the fundamentals of all the major routing protocols, but also the underlying principles on which they are based. The basic information in IP Routing is designed to help you begin configuring protocols for Cisco routers. Although author Ravi Malhotra assumes that readers have a basic understanding of TCP/IP and are somewhat familiar with Cisco router configurations, he also assumes that you find some or all of these protocols difficult to work with. His book presents concepts simply, as nuts and bolts. Malhotra's use of plain language, analogy, and the recurring example of an imaginary network, which grows in complexity as the book progresses, will help you understand fundamental concepts behind each protocol. Once you master these concepts, you will benefit from the detailed information contained in Cisco manuals and web pages (such as bug lists, new features, design guides, etc). Depending on your skill level, you can either read IP Routing from cover to cover or use it as a reference for any of the protocols presented. The book describes administrative tools available to all the routing protocols, including those that block the advertisement of routing updates, and those that set up preferences for one routing protocol over another. Honed by years of teaching Data Communications at major universities and managing IP networks in production environments, Ravi Malhotra's knowledge of this subject makes IP Routing is the ideal primer to Internet routing protocols.

Ruby is an absolutely pure object-oriented scripting language written in C and designed with Perl and Python capabilities in mind. While its roots are in Japan, Ruby is slowly but surely gaining ground in the US. The goal of Yukihiro Matsumoto, creator of Ruby and author of this book, is to incorporate the strengths of languages like Perl, Python, Lisp and Smalltalk. Ruby is a genuine attempt to combine the best of everything in the scripting world. Since 1993, Ruby mailing lists have been established, Web pages have formed, and a community has grown around it. The language itself is very good at text processing and is notable for its broad object orientation. Ruby is portable and runs under GNU/Linux (and other Unices) as well as DOS, MS Windows and Mac. Written by Yukihiro Matsumoto ("Matz"), creator of the language, this text is a practical reference guide covering everything from Ruby syntax to the specifications of its standard class libraries. The book is based on Ruby 1.6, and is applicable to development versions 1.7 and the next planned stable version 1.8.

One of the most significant features of Visual Basic .NET is the full support of object-oriented programming. For years, developers have been asking for it, but you may not be quite sure how it can help to create and maintain scalable .NET applications. VB.NET is a language that facilitates object-oriented programming, but does not guarantee good object-oriented code. That's where Object-Oriented Programming with Visual Basic .NET comes in. It will show you how to think about similarities in your application logic and how to design and create objects that maximize the benefit and power the .NET Framework enables. The concept of separating the interface from the implementation has been around for years, but with Object-Oriented Programming with Visual Basic .NET you'll put it all into practice and you'll never willingly go back to those old ways. With chapters on object fundamentals and class anatomy, you'll lay a foundation that will prepare you to think and apply code reuse principles. Following that, you'll be ready to dive deep into code and the dynamic ecology that it interacts with. Inheritance, containment, polymorphism, overloading, and overriding are just the beginning of this adventure. From there, you'll discover exception handling, reflection, serialization, and I/O. Packed with examples that will guide you through every step, Object-Oriented Programming with Visual Basic .NET is a guide for those with some programming experience. This book is for those who know Visual Basic 6.0 and are ready or have started the process of developing with Visual Basic .NET. It is an essential tool that will build your skills, as you become a master of Visual Basic .NET. It is one thing to know how to write object-oriented code. Knowing the when and the why is what makes good programmers.

Fifty years ago, in 1984, George Orwell imagined a future in which privacy was demolished by a totalitarian state that used spies, video surveillance, historical revisionism, and control over the media to maintain its power. Those who worry about personal privacy and identity--especially in this day of technologies that encroach upon these rights--still use Orwell's "Big Brother" language to discuss privacy issues. But the reality is that the age of a monolithic Big Brother is over. And yet the threats are perhaps even more likely to destroy the rights we've assumed were ours. Database Nation: The Death of Privacy in the 21st Century shows how, in these early years of the 21st century, advances in technology endanger our privacy in ways never before imagined. Direct marketers and retailers track our every purchase; surveillance cameras observe our movements; mobile phones will soon report our location to those who want to track us; government eavesdroppers listen in on private communications; misused medical records turn our bodies and our histories against us; and linked databases assemble detailed consumer profiles used to predict and influence our behavior. Privacy--the most basic of our civil rights--is in grave peril. Simson Garfinkel--journalist, entrepreneur, and international authority on computer security--has devoted his career to testing new technologies and warning about their implications. This newly revised update of the popular hardcover edition of Database Nation is his compelling account of how invasive technologies will affect our lives in the coming years. It's a timely, far-reaching, entertaining, and thought-provoking look at the serious threats to privacy facing us today. The book poses a disturbing question: how can we protect our basic rights to privacy, identity, and autonomy when technology is making invasion and control easier than ever before? Garfinkel's captivating blend of journalism, storytelling, and futurism is a call to arms. It will frighten, entertain, and ultimately convince us that we must take action now to protect our privacy and identity before it's too late.

JDBC is the key Java technology for relational database access. Oracle is arguably the most widely used relational database platform in the world. In this book, Donald Bales brings these two technologies together, and shows you how to leverage the full power of Oracle's implementation of JDBC. You begin by learning the all-important mysteries of establishing database connections. This can be one of the most frustrating areas for programmers new to JDBC, and Donald covers it well with detailed information and examples showing how to make database connections from applications, applets, Servlets, and even from Java programs running within the database itself. Next comes thorough coverage of JDBC's relational SQL features. You'll learn how to issue SQL statements and get results back from the database, how to read and write data from large, streaming data types such as BLOBs, CLOBs, and BFILEs, and you'll learn how to interface with Oracle's other built-in programming language, PL/SQL. If you're taking advantage of the Oracle's relatively new ability to create object tables and column objects based on user-defined datatypes, you'll be pleased with Don's thorough treatment of this subject. Don shows you how to use JPublisher and JDBC to work seamlessly with Oracle database objects from within Java programs. You'll also learn how to access nested tables and arrays using JDBC. Donald concludes the book with a discussion of transaction management, locking, concurrency, and performance--topics that every professional JDBC programmer must be familiar with. If you write Java programs to run against an Oracle database, this book is a must-have.

According to Microsoft, Windows 2000 Pro combines the friendly interface of Windows 98 with the famous stability of Windows NT. Windows 2000, the successor to NT, introduces many technologies that weren't available in NT, including Plug-and-Play, support for USB devices, power management features, and more. It's 25% faster than Windows 98 and three times as stable. Unfortunately, despite all the enhancements, Microsoft forgot to address one of NT's most glaring omissions: Windows 2000 doesn't include a printed user's manual. In Windows 2000 Pro: The Missing Manual, bestselling Windows NT author Sharon Crawford provides the friendly, authoritative book that should have been in the box. It's the ideal (and desperately needed) users' guide for the world's most popular corporate operating system. The book begins at the beginning: with a guide to what's new (for former NT users), a tour of the Desktop, and logging into the network. (Virtually all Windows 2000 users are on a network.) A special focus: organizing files, folders, and windows for maximum efficiency and minimum clutter. Detailed guidance for installing, removing, and troubleshooting new software and hardware comes next. More advanced chapters explore basic networking and Internet survival, including an excellent, step-by-step handbook for setting up a peer-to-peer network without having to hire a consultant, and chapters on configuring and using the Web (Internet Explorer), email (Outlook Express), and the built-in fax software. The final part of the book covers Windows 2000's local-management options: security, user profiles, backing up, and so on--all crowned by a beefy troubleshooting guidebook. Like the other books in the Missing Manual line, Windows 2000 Pro: The Missing Manual offers superb writing, special features for both absolute novices and power users, and offers authoritative, complete coverage of its subject. Windows 2000 Pro doesn't come with a manual-but if it did, Windows 2000 Pro: The Missing Manual would be it.
