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.

Apparatus and method for supporting bidirectional communication using unidirectional communication

A network security apparatus includes a management unit, a security policies monitoring unit, a security monitoring unit, a log security check unit, and a log transmission unit. The management unit receives network security apparatus setting information, security policies and log generation policies from the outside. The security policies monitoring unit checks whether the security policies comply with a set format. If the security policies comply with the set format, the security monitoring unit monitors whether a communication node communicates in compliance with the security policies. The log security check unit generates a monitoring log based on the log generation policies, and checks whether the monitoring log complies with a log setting format. If the monitoring log complies with the log setting format, the log transmission unit transmits the security log to the outside, thereby performing the outside network security.
