A computer implemented method for discovering a software product in a corporate data processing system comprises: connecting a first computer to a knowledge database, the knowledge database comprising at least one software product indicating identifier that is adapted to identify a software product. Subsequently, the first computer may select, from the knowledge database, one of the at least one software product indicating identifiers. Then the first computer may connect to the corporate data processing system. This step is followed by analyzing, by the first computer, the corporate data processing system for an occurrence of the software product indicating identifier in the corporate data processing system. Eventually the first computer may write a result of the step of analyzing to a list of discovered software products.
