Abstract
A method for creating rules for recognizing anomalies in a data stream of data packets. The method includes: providing a reference time signal having successive reference points in time; for at least two data portions from one or multiple data packets determined by a selected data packet type in a data stream section, ascertaining a time series of successive values of the relevant data portion, the values of the time series corresponding to the values of the relevant data portion or being a function of these values, the values of the relevant data portion each being assigned to a respective reference point in time of the respective reference points in time; carrying out a correlation method in order to ascertain, in each case, one correlation value for at least two different time series; creating a rule for the rule-based anomaly recognition method as a function of the ascertained correlation values.
