Introduction to Microsoft ISA ServerSolutions in this chapter:
- What Is ISA Server
- ISA Server Features Overview
- Who This Book Is For and What It Covers
The information technology (IT) world is full of acronyms; insiders refer to this vast maelstrom of initials as "alphabet soup." Sometimes it seems that there are so many acronyms—representing so many different concepts, products, components and protocols—that we've used up all the possible letter combinations and now we've started over. As you learn about this world, you'll find many instances in which the same acronym you had previously used in one context is now being used to describe something entirely different.
Hence, in this book, ISA has nothing to do with the Industry Standard Architecture (ISA) bus that long-time PC aficionados know and love (or at least know). Nor does it have anything to do with the Instrumentation, Systems, and Automation Society, an organization devoted to measurement and control technologies. Rather, ISA is yet another new server product from Microsoft (or more accurately, as you'll see, a new name for an improved version of a not-so-new product). This book will acquaint you with ISA Server's features and functionality.
In conjunction with the release of Microsoft's new business-oriented operating system, Windows 2000, the software company announced that it would be developing several new server products that would either provide new functionality in Windows 2000-based networks or provide enhancements to the functionality to add-on server products that were originally designed to run on Windows NT 4.0.
New versions of old standbys, such as Exchange 2000 and SQL Server 2000, were developed, with improved features and the ability to integrate with Active Directory. Brand-new products, such as the Microsoft Mobile Information 2001 Server and the Microsoft Application Center 2000 Server, were planned to take advantage of the latest trends in PC computing, such as wireless networking and the application service provider (ASP) explosion. Some of Microsoft's existing servers, such as SNA and Site Server, received new monikers like Host Integration Server and Commerce Server to reflect their updated features.
Another product that got a new name was Microsoft's Web-caching, filtering, and connection-sharing software package, Proxy Server. The Windows 2000-compatible version was code-named Comet in the development stages, but the final release was called Microsoft Internet Security and Acceleration Server 2000, or more simply, ISA Server...
Why "Security and Acceleration" Server?
Internet Security and Acceleration. It sounds good, but what does it mean? Let's look at those two factors—security and acceleration—and the role each plays in ISA Server,
