Claim 11:
12. A cyber attack detection device, configured to monitor data transiting via a user equipment, the device comprising a processor and a memory, the device configured to:
obtain at least a first decision provided using a first cyber attack detection technique and a second decision provided using a second cyber attack detection technique, the first and second decision indicating whether the data are associated with cyber attack traffic;
obtain a third decision provided using a third detection technique indicating whether the data are associated with cyber attack traffic, the third detection technique, in order to provide the third decision, using the first and second decisions and information representative of confidence levels assigned to the first and second detection techniques;
update the confidence levels assigned to the first and second detection techniques on the basis of the first, second and third decisions; and
adapt at least one rule applied by the first or the second detection techniques for providing the first and second decisions, the adaptation activated on the basis of the first, second and third decisions and of the updated confidence levels.
