A data packet is received at an input of a hardware switch unit, an output of the hardware switch unit being selected for sending the data packet or a copy as a function of data link layer information from the data packet and of a hardware address from a memory of the hardware switch unit. An actual value from a field of the data packet is compared by a hardware filter with a setpoint value for values from this field, the field including data link layer data or network layer data, and the data packet or a copy of the data packet being provided to a computing device as a function of a result of the comparison. The analysis for detecting an intrusion pattern in a network traffic in the computer network id carried out by the computing device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for intrusion detection in a computer network","description":"Device and method for intrusion detection in a computer network.
