Toward `verifying' a Water Treatment System [article]

Jingyi Wang and Jun Sun and Yifan Jia and Shengchao Qin and Zhiwu Xu
2018 arXiv   pre-print
In this work, we report our experience on combining model learning and abstraction refinement to analyze a challenging system, i.e., a real-world Secure Water Treatment system (SWaT).  ...  Modeling and verifying real-world cyber-physical systems is challenging, which is especially so for complex systems where manually modeling is infeasible.  ...  Conclusion and related work In this work, we conducted a case study to automatically model and verify a real-world water treatment system testbed.  ...
