Figure 47. Comparing the Bob process under the earlier process-based security model and the new

component-based security model in the .NET Framework

The new security model of the .NET Framework provides many features not available in a

process-based model. One of the biggest advantages is the ability of the common language

runtime to inspect a call stack during execution and verify that every assembly in the call stack

has the rights to perform the requested task. Because the call stack is now inspected at runtime,

an “untrusted” piece of code cannot lure a trusted piece of code into doing something. This

security addition helps applications that are built using various component libraries from different

vendors.

For more information about security, search for “security” in the .NET Framework Software

Development Kit.

Security-Related Enhancements for Authentication

To authenticate local and remote users, Windows Server 2003 provides the following two new

features of note:

• Credential Manager

• Constrained Delegation

Credential Manager

Credential Manager stores usernames and passwords and also stores links to certificates and

keys. As a result, a consistent, single sign-on experience is provided for users—including roaming

users. Single sign-on makes it possible for users to access resources over the network without

having to repeatedly supply their credentials.
