Constrained Execution Environment - A runtime environment that constrains mobile code to prevent its access to local system and network resources including the local file system, operating system settings, and parameters (e.g., Microsoft Windows Registry), and its ability to establish network connections other than to the mobile code's originating server. Examples of constrained execution environments include Java Runtime Environment sandbox, .NET Common Language Runtime, and a browser's JavaScript sandbox. E2.3.
