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

摘要

The invention relates to an automation network for monitoring the security of the transmission of data packets, comprising at least a first data processing means (1), which is provided for the transmission of data packets from a system component and in a system component and a second data processing means, wherein at least the first data processing means (1). is bidirectionally connected to the second data processing means for transmitting the data packets, wherein upon transmission of a data packet from the first data processing means (1) to the second data processing means detected by the second data processing means and response packets (5) are generated, which from the second data processing means to the first Data processing means (1) are returned, wherein the first data processing means (1) comprises a response filter (6) with which a check and subsequent rejection / acceptance of the response packets (5) d is feasible.
