1.3. Scope of This Guide

This guide is focused explicitly on the operations required to create and maintain a secure environment on servers running Exchange 2000. We examine two specific roles defined for servers — OWA front-end servers and back-end servers. We do not discuss how to run Internet Message Access Protocol 4 (IMAP4) or Post Office Protocol 3 (POP3) in a secure manner.

You should use this guide as part of your overall security strategy for Exchange, not as a complete reference to cover all aspects of creating and maintaining a secure environment. The diagram provides a high level view of these areas, the dark shaded box with white text is covered in this guide and the other shaded areas are covered in Security Operations for Microsoft Windows 2000 Server.
