Abstract: Provided herein is a method and system for the security of the file input and output of application programs. At a security process running step, an application program and an security process are executed independent of a main process of the application program. The security process is connected to a filter driver to control the filter driver. At an event generation step, the filter driver checks an event being processed by the application program, stops the processing of the event, and transfers event information regarding the event to the security process. At a control policy checking step, the security process compares the event information with a corresponding security control policy, and transfers the determination of the comparison to the filter driver. At an execution step, the filter driver continues the following processing of the corresponding event in conformity with the determination of the security process.

Abstract: Disclosed herein is a control system. The control server includes a management server, a plurality of client terminals configured to includes first and second client terminals and communicate with the management server, and a file server configured to store documents shared by the first and second client terminals. Each of the first and second client terminals includes an external device recognition module that reads codes of external devices that are communicably connected to or separated from the first or second client terminal. The management server includes an external device DB that stores the codes of the external devices, and an external device verification module that searches the external device DB for information about a code, and performs control so that a document stored in the file server is stored in an external device and is then transferred from the file server if the information about the code is found to exist.

Abstract: A system for controlling access to a file server is disclosed. The system for controlling access to a file server includes a management server, a plurality of client terminals for communicating with the management server, and a file server for storing one or more documents shared by the plurality of client terminals. Each of the client terminals includes a file server access module for verifying a user, and a security explorer tool driving module for outputting one or more documents stored in the file server. The management server includes an authorized user information database for storing authentication information, a user verification module for checking user information and searching for authentication information, and a document classification module for searching the file server for documents within the authorization limits based on the user, and transmitting the found documents to the security explorer tool driving module, thereby restricting documents depending on the users.
