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.

Abstract: An apparatus for protecting traffic trend in a network of a control system using artificial communication is provided. In accordance with an embodiment, the apparatus includes a communication terminal device installed in a network and configured to create and filter artificial communication. A communication server device determines whether to create artificial communication at a current time in the communication terminal device, requests a transmitting side-communication terminal device to create artificial communication, and requests a receiving side-communication terminal device to filter the artificial communication.
