This article details what the Windows® integrity mechanism is, why it was designed, how it works, and how you can code your applications for it. In this technical reference, we discuss the following topics:

• What is the Windows Integrity Mechanism?
  Discusses what an integrity mechanism is, the concept of integrity models, and why the Windows integrity mechanism was designed.
  
• Windows Integrity Mechanism Design
  Shows how the Windows integrity mechanism was designed to be an extension to the Windows security architecture.
  
• How the Integrity Mechanism Is Implemented in Windows Vista
  Shows how the Windows integrity mechanism was modified in Windows Vista® to include support for User Account Control (UAC), Microsoft Internet Explorer® Protected Mode, and the Windows Component Object Model (COM).
  
• Designing Applications to Run at a Low Integrity Level
  Shows how to design and develop applications to run at a low integrity level, and how to identify whether your application can run at a low integrity level.
  
• Appendix A: SDDL for Mandatory Labels
  Shows how to understand and implement Security Descriptor Definition Language (SDDL) functions for mandatory labels.
  
• Appendix B: Icacls and File Integrity Levels
  Shows how to use the Icacls command-line tool to manage the security settings on files. The Windows Vista version of Icacls supports mandatory labels on files.
  
• Appendix C: The Windows Integrity Mechanism and Windows Kernel Mode Code Integrity
  Discusses how the Windows integrity mechanism enhances the security of the Windows kernel by requiring that all kernel mode binaries be digitally signed on 64-bit computers that are running Windows Vista.
  
• Appendix D: Getting the Integrity Level for an Access Token
  Shows how to use the GetTokenInformation API to get the integrity level for an access token.
