1. A method for identifying an inadmissible message of a manipulated control device of a vehicle using a second control device of the vehicle, the method comprising:
receiving a first message of a first control device of the vehicle via a first bus system using the second control device of the vehicle;
determining a bus system, which is associated with the received first message, using the second control device, and
if the determined bus system differs from the first bus system, then determining the received first message as an inadmissible message of the first bus system by means of the second control device;
identifying the first control device as the manipulated control device using the second control device if the received first message has been identified as an inadmissible message; and
providing an alarm message to a vehicle-external server using the second control device if the received first message has been identified as an inadmissible message,
wherein the second control device is an only trustworthy source of the first message.
