Abstract

Device and method for intrusion detection in a computer network. A data packet is received at an input of a hardware switch unit, an actual value from a field of the data packet being compared in a comparison by a hardware filter with a setpoint value for values from the field, the field including data link layer data or network layer data, a value for a counter determined as a function of a result of the comparison being provided by the hardware switch unit, and a computing device determining a result of the intrusion detection as a function of the value of the counter in the hardware switch unit and independently of information from the data packet, in particular, without an evaluation of information from the data packet by the computing device.
