Privileged Code

When you design and build secure assemblies, be able to identify privileged code. This has important implications for code access security. Privileged code is managed code that accesses secured resources or performs other security sensitive operations such as calling unmanaged code, using serialization, or using reflection. It is referred to as privileged code because it must be granted permission by code access security policy to be able to function. Non-privileged code only requires the permission to execute.

Privileged Resources

The types of resources for which your code requires code access security permissions include the file system, databases, registry, event log, Web services, sockets, DNS databases, directory services, and environment variables .

Privileged Operations

Other privileged operations for which your code requires code access security permissions include calling unmanaged code, using serialization, using reflection, creating and controlling application domains, creating Principal objects, and manipulating security policy.

For more information about the specific types of code access security permissions required for accessing resources and performing privileged operations, see "Privileged Code" in Chapter 8, "Code Access Security in Practice."
