Abstract

A device and method for intrusion detection in a computer network. A data packet is received at an input of a hardware switch unit, an output of the hardware switch unit is selected for sending the data packet or a copy as a function of security layer information from the data packet and of a hardware address, context information for the data packet being determined, an actual value from a field being compared in a comparison by a hardware filter with a setpoint value for values from this field, the field including security layer data or mediation layer data, and an interrupt for a computing device being triggered as a function of a result of the comparison, an analysis for detecting an intrusion pattern in a network traffic in the computer network, triggered by the interrupt, being carried out as a function of the context information for the data packet.
