Abstract
A data transfer apparatus and method, which fundamentally prevent the possibility of intrusion from an external network into an internal network that provides files, thus enabling data to be reliability transferred in a situation in which information cannot be exchanged. The data transfer apparatus includes an internal network connection unit for receiving data from a host of an internal network. An internal network control unit for performing control such that the data is unidirectionally transmitted. A write control unit checks integrity of the data received from the internal network control unit and detects status of the storage unit. An external network connection unit receives a request from a host of an external network. A read/write control unit searches for, reads, and deletes data stored in the storage unit at a request of the external network host.
