Abstract

A method operates a technical or non-technical system. At least one information element of a first type which relates to the system and is dependent on the respective system state of the system is transmitted according to the method from at least one first facility of the system to at least one second facility. The second facility uses at least one information element of a second type which originates neither from the first facility nor from a different facility of the system, i.e. it comes from a source other than the system, to estimate the system state, checks, on the basis of the estimated system state, whether the received information matches the estimated system state to a predefined extent, and, in the event of a match to the predefined extent, regards the information as trusted, and otherwise generates a warning signal indicating a possible data attack.
