Abstract: An apparatus and method for supporting bidirectional communication using unidirectional communication. The apparatus for supporting bidirectional communication using unidirectional communication includes an internal network module for performing bidirectional communication with an internal network and communicating with an external network module depending on a communication mode, the external network module for performing bidirectional communication with an external network and communicating with the internal network module depending on the communication mode, and a communication control module for controlling, of first unidirectional communication from the internal network module to the external network module and second unidirectional communication from the external network module to the internal network module, the second unidirectional communication, thus controlling a communication function corresponding to the communication mode, wherein the communication mode includes a unidirectional communication mode, a conditional bidirectional communication mode, and a bidirectional communication mode.

Abstract: Disclosed herein is a method for detecting an anomaly state based on screen output. The method includes receiving the output screen of a target device to be monitored, setting a target region to be examined in the output screen of the target device to be monitored, calculating a feature value vector corresponding to the state of the target region to be examined, calculating an anomaly score using a pretrained auto-encoder by receiving the feature value vector as input, and determining whether the target device to be monitored is anomalous using the anomaly score.

Abstract: An apparatus for supporting data communication between separate networks, which includes an internal network connection module for sending data, received from an internal network, to an intermediate connection module through one-way communication and sending data, received from the intermediate connection module through first one-way communication under the control of an internal network bypass switch, to the internal network; an external network connection module for sending data, received from the intermediate connection module through one-way communication, to an external network and sending data, received from the external network, to the intermediate connection module through second one-way communication under the control of an external network bypass switch; and the intermediate connection module for temporarily storing and managing intermediate data received from the internal network connection module or the external network connection module.
