  1. Microsoft Installer Technologies and patch management approaches

  2. Internal Competition Breeds Variety • MSI (Microsoft Installer Service) • Microsoft Update • Office Update • SUS (Software Update Service) • SMS (System Management Server) • Others (MS SQL group, MS Exchange Group,…)

  3. Stated Goals: end of 2004? • One method for updating applications (MSI version 3.0) • One method for updating operating systems (update.exe)

  4. Current Problems • Inconsistent UI • Inconsistent features • Inconsistent reporting results • All leading to unpatched machines

  5. MSI Capabilities • Compatible installers can be deployed via Group Policies • Compatible installers can be created by 3rd parties • Transforms can be used to add customizations without requiring installer source code access • Applications can be made “self-healing”

  6. MSI Capabilities continued • Users do not need to be local administrator • Introduces UI consistency into application installers • Handles removal as well as installation

  7. MSI problems • New versions of MSI can’t be deployed using MSI • Not all MSI installers can be used with Group Policies • Microsoft HotFixes and QFEs can’t be installed with MSI • MSI can’t update core OS components

  8. Microsoft Update Features • Web interface • Can install core operating system components

  9. MS Update disadvantages • Mostly a pull technology • Users must be member of local administrator group • Specific to Microsoft issued code • No “role based” deployment • Subject to denial of service attacks • No “self-healing” • Can be confused about what has been installed

  10. Office Update • Nearly the same as Microsoft Update • Simply another web site with a different group maintaining a different set of configuration files (and ActiveX controls?)

  11. SUS • Locally maintained version of Microsoft Update • SUS only supports OS updates at this time (no MS SQL Server or Office Updates) • Can only distribute Microsoft signed binaries, no 3rd party support • SUS administrators get to decide which updates from Microsoft to deploy locally

  12. SUS and machine roles • Like Microsoft update, SUS does not have the concept of roles • Sites desiring “role” based machine deployment need multiple SUS servers

  13. SMS • Microsoft’s heavy weight solution • Used by Microsoft’s internal ITG for deployment and patch management • Can be used to deploy OS components, MS applications, 3rd party applications • Role based or global • Can support downlevel products • Central deployment of hotfixes

  14. (over stated ) Conclusion • Microsoft will continue to NOT meet our needs over the next two years • Lack of support for 3rd party applications via update.exe • Lack of self-healing via update.exe • Lack of OS patching via MSI • A continuing revenue stream from SMS
