description A system, inspection device and method for securely executing control applications, wherein at least one event is defined for at least one control application and the event is triggered upon potential manipulation of program code associated with the control application and/or of at least one peripheral connected to a program flow controller processing the program code, where the program flow controller monitors a flow of the control application for deviations from an expected flow behavior and triggers the defined event upon a deviation, following triggering of the defined event, the program code is processed further by the program flow controller and the event is reported to an inspection device separate from the program flow controller where the inspection device places the control application and control components with an interdependency thereon into a predefined safe operating state upon detecting a flow behavior of the control application that contravenes the inspection rules.
