The DepAuDE architecture provides middleware to integrate fault tolerance support into distributed embedded automation applications. It allows error recovery to be expressed in terms of recovery strategies, i.e., lightweight code fragments separated from the application code. At run time, the middleware orchestrates their execution. This paper reports on… (More)
Distributed intelligence and secure interconnected communication networks constitute recognized key factors for the economic operation of electricity infrastructures in competitive power markets. Hence, electric power utilities need to extend risk management frameworks with adequate tools for assessing consequences of ICT (Information and Communication… (More)
In order to evaluate the resiliency of architectures supporting teleoperation functions, a laboratory testbed, described in the paper, is being developed by CESI RICERCA in the context of the European Project CRUTIAL. The testbed implements a prototypal but significant power system control architecture with its integrated ICT infrastructure.
The research described concerns the partitioning of large control applications for a multi-computer system in order to meet plant localization requirements and to exploit paral-lelism. The considered applications have hierarchical structure and are composed by a network of automata. Our application domain is the automation of power stations and electricity… (More)
The objective of the chapter is to present the role of cyber security experiments within a methodological approach for the evaluation of cyber risks in grid control systems. As a starting point, a cyber-power risk index has been defined to support the identification of relevant risk factors across network attack models. Instances of attack models have been… (More)
The work presents a methodology for the experimental evaluation of cyber failures to power grid control networks. The methodology has been applied to standard communications of the grid telecontrol test bed in the Power Control System - Resilience Testing Laboratory of RSE for producing performance measures about the effects of both accidental and… (More)
