The invention relates to a method (800) for detecting a denial-of-service attack in a communication network (300, 500), wherein an attacker (201) with a source network address transmits a request with a response network address to a target server (103) in order to request a transmission of a response packet to the response network address from the target server (103), the response network address differing from the source network address of the attacker (201), and the target server (103) transmits a response packet to the response network address in response to receiving the request. The method (800) has the following steps: receiving (801) a data packet originating from the target server (103) by means of a monitoring server (301), to which the response network address is assigned, and outputting (802) a warning signal (402) by means of the monitoring server (301) if the received data packet is an unrequested response packet received by the monitoring server (301). |
