“…We have applied our techniques to a non-trivial case study involving a prosumer-based smart microgrid, and applied CTL model checking for automatically checking the localized verification conditions. It would be interesting to enrich filter functions with further information about grid stability, optimization of energy consumption [4], or timing constraints [6]. For the smart microgrid case study we have manually derived the CTL verification conditions, but it should be possible to automatically generate these temporal logic formulas from the definition of filter functions.…”

A security policy specifies a security property as the maximal information flow. A distributed system composed of interacting processes implicitly defines an intransitive security policy by repudiating direct information flow between processes that do not exchange messages directly. We show that implicitly defined security policies in distributed systems are enforced, provided that processes run in separation, and possible process communication on a technical platform is restricted to specified message paths of the system. Furthermore, we propose to further restrict the allowable information flow by adding filter functions for controlling which messages may be transmitted between processes, and we prove that locally checking filter functions is sufficient for ensuring global security policies. Altogether, global intransitive security policies are established by means of local verification conditions for the (trusted) processes of the distributed system. Moreover, security policies may be implemented securely on distributed integration platforms which ensure partitioning. We illustrate our results with a smart grid case study, where we use CTL model checking for discharging local verification conditions for each process under consideration. * This work was carried out as part of the DMILS project www.d-mils.org which is funded by the European Commission under the contract Nr.
