Description
An application's trust level determines the permissions granted by the ASP.NET Code Access Security (CAS) policy. An application with full trust permissions may access all resource types on a server and perform privileged operations, while applications running with partial trust have varying levels of operating permissions and access to resources. The CAS determines the permissions granted to the application on the server. Setting a level of trust compatible with the applications will limit the potential harm a compromised application could cause to a system.
