Topic Last Modified: 2005-05-25

Trustworthy Computing means helping to ensure a safe and reliable computing experience that is both expected and presumed. This goal is achieved by addressing the following set of issues that affect the level of trust placed in computing: security, privacy, reliability, and business integrity. The following table describes each of these issues in detail.

Trustworthy Computing goals

Trustworthy Computing goals Description


An organization can expect that systems are resilient to attack, and that the confidentiality, integrity, and availability of the system and its data are protected.


An organization is able to control their information and feel confident it is not only safe and used appropriately, but in a way that provides value to them.


An organization can depend on the software and hardware in their infrastructure to fulfill its intended functions.

Business integrity

Software and hardware vendors work together efficiently and behave in a responsive and responsible manner.

Although all of the issues listed are critical to ensuring a trustworthy Exchange messaging system, this guide focuses on achieving reliability and availability goals. Both Microsoft Windows Server™ 2003 and Exchange 2003 include features that can help achieve these goals. For specific information about these reliability features, see "Selecting Editions of Exchange and Windows" in Operating System and Application Measures.

For information about how to achieve security and privacy goals in your Exchange 2003 organization, see the Exchange Server 2003 Security Hardening Guide.
