Abstract
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.
