AUTOMATION NETWORK AND METHOD OF SURVEILLANCE FOR SECURITY OF THE TRANSMISSION OF DATA PACKETS

摘要

An automation network for monitoring the security of a transfer of data packets includes a first processing device configured to transfer a data packet from an installation component and to the installation component, and a second data processing device which is bidirectionally connected to the first data processing device. The second data processing device generates at least one response packet, when detecting a transmission of the data packet from the first data processing device, and sends the at least one response packet back to the first data processing device. The first data processing device includes a response filter which is configured to execute a check and subsequent rejection/acceptance of the at least one response packet.
