Abstract: A system and method for controlling execution of an interpreted language. Statements of the interpreted language to be executed by a script engine are intercepted by a protection module and control is passed to a script helper module that is associated with the script engine. The script helper module establishes a secure communications channel with an authorization component and passes the statements and an authorization request to the authorization component. The authorization component sends a reply to the script helper module which either permits the script engine to execute the statement or cancels the attempted execution. When the script engine is loaded, a list is updated identifying the script engine. If a script helper module is not present for the loaded script engine, a boot-strap loader is called to load the script helper module. A special information block contains data as to the location of the interception points.

Abstract: A method and device monitor usage of external storage media. The method and system selectively shadow I/O (input/output) from/to only external storage media. The method selectively shadows only accesses to external storage media connected to a computer. The method detects a data access to an external storage medium and writes a copy of the accessed data to a storage location other than the external storage medium. In one embodiment, the access is a write operation. In one embodiment, the method intercepts an I/O request from the computer to an external storage media drive in which the external storage media is inserted. In the case of the Windows NT or Windows 2000 operating systems, the intercepted I/O requests are preferably IRP_MJ_CREATE, IRP_MJ_WRITE, IRP_MJ_CLOSE and IRP_MJ_FILE_SYSTEM_CONTROL packets. An apparatus comprises a detector and a storage connected to the detector. The detector receives I/O requests to an external storage medium. The storage is one other than the external storage medium.
