A system and method for analyzing a patch file determine the similarity between a patch file of an application program and an existing file in terms of an operation pattern and a file type and also determine whether risky behavior is performed by the patch file, thereby detecting a file disguised as a patch file. The system for analyzing a patch file includes: a program analysis module configured to collect setup information configured in an application program and generate the collected information as reference information; a reference information database (DB) configured to store the reference information; a patch file analysis module configured to generate setup information configured in a patch file of the application program as patch information by analyzing the patch file; and a comparison module configured to search for reference information and compare the patch information with the reference information.

System and method for analyzing patch file

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.

Data processing system security device and security method

A file security management apparatus and method which protect various types of systems for executing files, entering from the outside, from malicious code, and which prevent data from being divulged from the systems and also prevent the systems from operating erroneously, thereby ultimately protecting the systems. The file security management apparatus includes a conversion module configured to convert an incoming file, received by a system, into a monitoring target file; a search module configured to identify a selection for the execution of the monitoring target file, and to output incoming files, configured in the monitoring target file, into a search window; and a security module configured to decrypt the monitoring target file to the incoming file, and to perform processing so that the incoming file is executed via a corresponding application program in an isolated drive set as an isolated environment.

File security management apparatus and management method for system protection

A system for controlling exit of saved data from a security zone, comprising an access control device, the access control device comprising an access detection module for detecting access of an application to a security zone and access of an application to a general zone, a target checking module for comparing the application, detected by the access detection module, with a list and then controlling access of the application to the security zone and access of the application to the general zone, and a processing control module for controlling writing of data of the application to the general zone.
