deutsche Version
WUSCH is acronym for Windows Update Service at CHemnitz University of Technology.

Basis und target

This service is an offer of the computing center (URZ) to improve the security on Windows-based PCs used in the campus net. The basis is the opportunity, integrated in new Windows platforms, to update an installation automatically by Windows-Update. Normally this updates will be downloaded from Microsoft servers.

WUSCH is about to offer this service in the campus net by the Chemnitz University of Technology. A decrease of extern traffic and a possible local administration of such Updates are the advantages (see Scope of service). Now it is possible to update computers without direct access to the internet.

Service Level Agreement (SLA)

Scope of service

The URZ is running servers saving security patches, provided by their manufacturer, to distribute them autmatically. The synchronisation to Microsoft is done normally once per day.

The approvement of those patches is done by URZ after a simple review. This includes a classification and, if possible, a successful test installation without any negative results or effects.

Due to heterogeneity on target systems responsibility for correctness of this patches is declined. This also includes compatibility to the running system.

Service packs for the operating system because of their complexity aren't provided for automatic installation. Those can be downloaded for manual installation from Security recommendation for Windows-PSs/Service Packs (german).
