UPS start from batteries 2 The battery autonomy finished as Fire Brigate was not able to eliminate water in time. 3 The full functionality of the SGT station is restored 4 hours 90 min.

10 IRRIIS GdS: La Security nei sistemi di controllo e automazione, nelle reti e infrastrutture San Felice (MI), 26 giugno Pagina 10 IRRIIS Inter-LCCI Communication Highway LCCI 1 LCCI 2 MIT integration with existing SCADA systems

11 IRRIIS GdS: La Security nei sistemi di controllo e automazione, nelle reti e infrastrutture San Felice (MI), 26 giugno Pagina 11 MIT Add-On Components Functional Requirements DETECT AS EARLY AS POSSIBLE the anomalous status and NOTIFY it to the dependent infrastructures. PROVIDE EARLY WARNING of deteriorating system conditions to internal and/or external LCCI operators. ESTIMATE the probability of disrupt of his own LCCI and NOTIFY to the dependent infrastructures.

12 IRRIIS GdS: La Security nei sistemi di controllo e automazione, nelle reti e infrastrutture San Felice (MI), 26 giugno Pagina 12 MIT Add-On Components Requirements ASSESS the own infrastructure RISK due to information about neighbouring status. PREVENT incident to mitigate cascading effects on dependent infrastructures. HANDLE THE EMERGENCY if needed by negotiating coordinate actions

13 IRRIIS GdS: La Security nei sistemi di controllo e automazione, nelle reti e infrastrutture San Felice (MI), 26 giugno Pagina 13 Overall MIT architecture

14 IRRIIS GdS: La Security nei sistemi di controllo e automazione, nelle reti e infrastrutture San Felice (MI), 26 giugno Pagina 14 MIT Add-On Components Internal Assessment –Tool to extract LCCI functional status Risk Assessment –Risk Estimator –Incident Knowledge Analyser Emergency Management –Assessment of cascading/escalating effects –Display of Emergency Management Procedures –Negotiator

15 IRRIIS GdS: La Security nei sistemi di controllo e automazione, nelle reti e infrastrutture San Felice (MI), 26 giugno Pagina 15 Internal Assessment functions Information extraction and fusion from different existing tools and SCADA data bases. Use the previous information to evaluate the current functional status of the LCCI. Predict the possible future states, based on the actual state and the future scheduled events.

16 IRRIIS GdS: La Security nei sistemi di controllo e automazione, nelle reti e infrastrutture San Felice (MI), 26 giugno Pagina 16 Internal Assessment Workflow

17 IRRIIS GdS: La Security nei sistemi di controllo e automazione, nelle reti e infrastrutture San Felice (MI), 26 giugno Pagina 17 Internal Assessment Benefits Provide the local operator with a unique picture about the current and future internal LCCI state, allowing him to enable or disable information sharing with the neighbouring LCCIs. Provide input for neighbouring LCCIs about the local infrastructure status. Provide input for neighbouring LCCIs about the future predicted infrastructure states.

18 IRRIIS GdS: La Security nei sistemi di controllo e automazione, nelle reti e infrastrutture San Felice (MI), 26 giugno Pagina 18 Incident Knowledge Analyser functions It will be able to assess and fuse information from multiple databases containing past incidences. It will check immediately whether on-going failures are notified as causes of major incidents in the past. It will extract possible known cascading effects of on-going failures. It will store new incidents.

20 IRRIIS GdS: La Security nei sistemi di controllo e automazione, nelle reti e infrastrutture San Felice (MI), 26 giugno Pagina 20 Incident Knowledge Analyser Benefits Each LCCI operator can make the most of the available knowledge about all the known disruptions, being warned if an on-going failure already happened in the past and led to disruption of operation even if that occurred in other LCCIs (in fact, not all the LCCIs must have experienced the same failures and the related disruptions). LCCI can make the most of findings by other sources, for example research or training outcomes.

21 IRRIIS GdS: La Security nei sistemi di controllo e automazione, nelle reti e infrastrutture San Felice (MI), 26 giugno Pagina 21 Risk Estimator functions Reasoning about the states of processes and services, mainly focusing on the services to be exchanged with other LCCIs. Estimating the levels of risks associated to services exchanges with other LCCIs. Working on a service-process model of the LCCIs by making use of a fuzzy rules-based mechanism.

22 IRRIIS GdS: La Security nei sistemi di controllo e automazione, nelle reti e infrastrutture San Felice (MI), 26 giugno Pagina 22 Visualisation of the levels of risks associated to the services LCCI internal state estimation After external & internal states correlation

24 IRRIIS GdS: La Security nei sistemi di controllo e automazione, nelle reti e infrastrutture San Felice (MI), 26 giugno Pagina 24 Risk Estimator Benefits Make operators more aware about the global LCCIs state, correlating local LCCI and external LCCIs states. Give to the LCCIs operators schematic pictures evidencing the potential risks to loss internal and external services. Improve coordination between the LCCI operator and the neighbouring LCCIs.
