Security Changes Under Windows Server 2003

Windows Server 2003 is the first operating system to be launched under the Trustworthy

Computing initiative. As a result, significant changes have been made to ensure that Windows

Server 2003 is one of the most secure operating systems ever released by Microsoft. To make

this commitment a reality many new features and changes have been added to the product.

Because Windows Server 2003 includes too many new features to list, the sections that follow

discuss changes of particular interest to organizations that are migrating from Windows NT 4.0

Server. This section provides an overview of key differences in security-related features between

Windows NT 4.0 and Windows Server 2003. In particular, changes to security-related features are

discussed in more detail for IIS 6.0, COM+, the .NET Framework, authentication, access control,

and network security.

Goals of the Trustworthy Computing Initiative

A short way of introducing the Trustworthy Computing initiative is to look at its goals, and then

review the features and changes to Windows Server 2003 that help implement these goals.

The Trustworthy Computing Initiative considers trust from a user’s point of view. The goals are

designed to answer key user questions: Is the technology there when I need it? Does it keep my

confidential information safe? Does it do what it’s supposed to do? And do the people who own

and operate the business that provides the technology always do the right thing? These are the

goals that any trustworthy computing has to meet as the following table summarizes.

Trustworthy Computing Initiative Goals

Goal Description

Security The customer can expect that systems are resilient to attack and

that the confidentiality, integrity, and availability of the system and its

data are protected.

Privacy The customer is able to control data about themselves, and those

using such data adhere to fair information principles

Reliability The customer can depend on the product to fulfill its functions when

required to do so.

Business The vendor of a product behaves in a responsive and responsible

manner.

Microsoft has created a framework to track and measure its progress in meeting the security

goals and objectives of the Trustworthy Computing initiative. For more information, see the

Building a Platform for Trustworthy Computing

white paper on the Microsoft Security Web site and

Windows Server 2003 Security Guide
