Understanding Code Access Security in Reporting Services

Understanding Code Access Security in Reporting Services

SQL Server 2000

The Microsoft® .NET Framework provides a rich security system that can run code in tightly constrained, administrator-defined security contexts. The .NET Framework system that secures code is referred to as code access security (or evidence-based security). Under code access security, a user may be trusted to access a resource, but if the code the user executes is not trusted, access to the resource will be denied.

Security based on code, as opposed to specific users, permits security to be expressed for custom assemblies or data, delivery, rendering, and security extensions that you develop for Reporting Services. Your extension code may be executed by any number of users of Reporting Services, all of which are unknown at development time. The custom assemblies or extensions that you develop require specific security policies in Reporting Services. These security policies are represented as types in the .NET Framework. For a more complete understanding of code access security in the .NET Framework, see "Code Access Security" at this Microsoft Web site.
