Abstract: Various embodiments herein each include at least one of systems, methods, and software that provide domain-specific configurable fraud prevention solutions. One such embodiment, in the form of a method, includes presenting a user interface including a plurality of controls tailored to present and receive input defining fraud detection rules. Input may then be received within the user interface defining a fraud detection rule where the input identifies at least one transaction-related data item and a data condition. This method then stores the received input as a fraud detection rule in a rule base.
