  • Data processing system security device and security method
    Patent number: 9990493
    Abstract: Provided is a security device and method that protect a data processing system from various types of malicious code and prevent the divulgence of data and erroneous operation. The security device for a data processing system includes: an execution module configured to be called by a security loader when a stub file, including a security loader formed in a routine form and a stub composed of an original executable file, is executed, and to perform processing so that the original executable file restored from the stub by the security loader is executed; and a monitoring module configured to monitor the operation of the data processing system attributable to the execution of the restored original executable file.
