PROBLEM TO BE SOLVED: To provide a switch connection control system for a communication path that attains flexible cooperation between an internal network and an external network while preventing direct intrusion of an access from the external network into the internal network by using a physical means. SOLUTION: The switch connection control system for a communication path adopts a switch connection controller that is interposed in the communication path and exclusively selects connection to one communication path or connection to the other communication path to provide a security system for preventing illegal intrusion to terminals and systems distributed on purposes by employing a sea-saw type switching technology. Since the sea-saw type switching technology physically disconnects the external network from the internal network with a control signal of an access request on purpose in this way, the system can surely protect data from illegal acts. |
