Abstract
The invention relates to a method for monitoring a security network interface unit (), for example a firewall, which receives a stream of data packets via a first interface (), checks said data stream with respect to filtering rules, and outputs said data stream to a second interface (). The method has the steps of duplicating and outputting the data stream to the second interface (), checking the output data stream for inadmissible data traffic, transmitting a warning message to the security network interface unit if inadmissible data traffic is detected in the data stream, and restricting the data stream by means of the security network interface unit if the warning message is received in the security network interface unit (). The device or the system according to the invention comprises units which are designed to carry out the aforementioned method.
