CONTROL FLOW INTEGRITY SYSTEM AND METHOD

A CFI system constituted of: at least one protection module, each comprising a respective allowable flow model associated with at least one of a plurality of portions of a process; and at least one process protection manager, arranged, responsive to a control flow instruction in one of the plurality of portions of the process, to: compare one or more parameters of the control flow instruction to the allowable flow model of the associated protection module; and responsive to an outcome of the comparison indicating that the compared parameters do not meet a respective parameter of the allowable flow model, generate a predetermined signal, wherein each protection module is implemented as a shared object, wherein each process protection manager is implemented as a shared object, and wherein the at least one protection module and the process protection manager are loaded into the process.
