A method and apparatus for prioritising alarms in an account fraud detection system. The method involves assigning a numeric weight to each of a plurality of behavioural characteristics of an alarm raised against an account, and computing a fraud score for that alarm responsive to those numeric weights. Numeric bounds may be imposed on the score, and a term may be added dependent on the number of alarms raised on the account.
