Static Detection of Logic Flaws in Service-Oriented Applications

Application or business logic, used in the development of services, has to do with the operations that define the application functionalities and not with the platform ones. Often security problems can be found at this level, because circumventing or misusing the required operations can lead to unexpected behaviour or to attacks, called application logic attacks. We investigate this issue, by using the CaSPiS calculus to model services, and by providing a Control Flow Analysis able to detect and prevent some possible misuses.
