Microsoft Internet Security and Acceleration Server 2000 is more than a simple firewall product. A simple firewall product contains packet and circuit filtering, but Microsoft adds application filtering, which allows for extensibility. In addition to filtering, ISA also provides caching, publishing, and routing. These are features that web administrators are looking for in a product that provides web security and network performance enhancements. The reader will also receive comprehensive appendices on information related to all ISA Server performance counters and ISA Server messages. Readers will find information in this book that they won't find in any other book on the market, including how to install ISA clients via SMS, publish products such as SQL Server and Oracle, and set up ISA to prevent SMTP hacks.
