Enforcement Monitoring wrt. the Safety-Progress Classification of Properties
Résumé
Runtime enforcement is a powerful technique to ensure that a program will respect a given set of properties. We extend previous works on this topic in several directions. Firstly, we propose a generic notion of enforcement monitors based on a memory device and finite sets of control states and enforcement operations. Moreover, we specify their enforcement abilities wrt. the general safety-progress classification of properties. Furthermore, we propose a systematic technique to produce an enforcing monitor from the automaton recognizing a given safety, guarantee, or response property. Finally, we depict a prototype toolbox implementing the features proposed in this paper.
