    Abstract: 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.

    Abstract: A physical unidirectional communication apparatus and method intended to utilize a structure that exploits an electrical signal by which data cannot be transmitted and to guarantee the reliability of data transmission via a transmission method that uses the structure. The physical unidirectional communication apparatus includes a unidirectional data transmission line, a data reception status transmission line, an internal network connection system unit for performing communication with an internal network transmission host and transmitting transmission data to an external network connection system unit through the unidirectional data transmission line, and the external network connection system unit for performing communication with an external network reception host, receiving the transmission data from the internal network connection system unit, generating reception status information of the transmission data, and transmitting the reception status information to the internal network connection system unit through the data reception status transmission line.

    Abstract: An out-of-vehicle device interface apparatus includes a request message reception unit, a response message request unit, and a response message transmission unit. The request message reception unit receives a request message from an out-of-vehicle device, generates electrical signals in electric lines, and transfers the request message. The response message request unit requests response messages for the request message from one or more devices constituting an in-vehicle network based on one or more of the electric lines in which electrical signals have been generated. The response message transmission unit receives the response messages from the one or more devices, and transfers the response messages to the out-of-vehicle device via unidirectional communication.

    Abstract: A whitelist-based network switch defines a whitelist and a handling rule based on an access control list, security policies, etc., and monitors and blocks network traffic based on the whitelist and the handling rule. The whitelist-based network switch includes a whitelist monitoring unit for storing a whitelist including permitted communication rules, monitoring one or more packets input through a plurality of switch interfaces based on the whitelist, and permitting communication of each packet conforming to the whitelist, and a whitelist management unit for updating the whitelist and transmitting an updated whitelist to the whitelist monitoring unit.
