Verfahren zum Überwachen eines Datenverkehrs eines Kraftfahrzeugs und Kraftfahrzeug mit einem Angriffserkennungssystem

The invention relates to a method for monitoring data traffic of a motor vehicle (10) by means of an attack detection system (12), wherein the attack detection system (12) for monitoring data traffic analyses at least a first part (D1) of the data from the data traffic. In this case, the first part (D1) of the data is stored in a first operating state (B1) of the motor vehicle (10). In a second operating state (B2) of the motor vehicle (10), which is different from the first operating state and in which the motor vehicle (10) is stationary and not in a driving mode, the stored first part (D1) of the data is analysed by the attack detection system (12).
