HOW TO: Adjust .NET Framework Security on a Zone-by-Zone Basis (815148)


The information in this article applies to:

  • Microsoft .NET Framework 1.0
  • Microsoft .NET Framework 1.1

IN THIS TASK

SUMMARY

This article describes how to adjust the .NET Framework security on a zone-by-zone basis. The level of trust that you assign to an assembly determines what system resources that assembly has access to. By default, trust is assigned to managed assemblies based on the zone that the assembly resides in. For example, assemblies that run from the local computer receive the Full trust level. Assemblies that run from the Internet are assigned the None trust level. This article describes how to adjust the trust levels that are assigned to different zones and thereby to assemblies that run from those zones.
