A system and system for controlling the execution of executable files. The executables are identified by either a cryptographic digest or a digital certificate. The cryptographic digest is computed from the binary image of the executable. An executable that is attempting to execute is intercepted by a protection module that consults a database of stored rules over a secure channel to determine whether or not the executable can be identified as a permitted executable and whether or not it has permission to execute on a particular computer system under certain specified conditions. If a stored permission is available, it is used to control the execution. Otherwise, the user is consulted for permission.

On-line centralized and local authorization of executable files

A system and method for controlling the execution of executable files. The executables are identified by either a cryptographic digest or a digital certificate. The crytographic digest is computed from the binary image of the executable. An executable that is attempting to execute is intercepted by a protection module that consults a database of stored rules over a secure channel to determine whether or not the executable can be identified as a permitted executable and whether or not it has permission to execute on a particular computer system under certain specified conditions. If a stored permission is available, it is used to control the execution. Otherwise, the user is consulted for permission.

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.

Generic framework for runtime interception and execution control of interpreted languages

A system and method for securing data on a mass storage device. A centralized device permission store contains device identifiers for the mass storage devices to be secured along with keys of a symmetric cipher that have been encrypted with public keys or pass phrases of authorized users of the devices. A list of these users also contained in the store. A helper module provides the private key or pass phrase, for imported keys, needed to decrypt the key of the symmetric cipher, which is used to encrypt and decrypt blocks of data stored on the mass storage device. When a read request is made, a protection module intercepts the request, obtains the block from the mass storage device and decrypts the block. When a write request is made, the protection module intercepts the request, encrypts the block and has it stored on the mass storage device.

Transparent encryption and access control for mass-storage devices

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 asociated 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.
