The invention discloses a model evaluation method based on a multiple-index-dimension composite distance. According to the method, various information system risk assessment models already existing are firstly analyzed, so that various information indexes are extracted from the information system risk assessment models; according to data collected from an information system, parameters are normalized, the vector quantity length is calculated according to index dimensions, and finally the composite distance is obtained. Objective evaluation can be performed on the risk analyzing models accurately according to the collected data, people can be helped to predict the occurrence of risks, and errors possible to happen in future are prevented.
