Providers of critical infrastructure services strive to maintain the high availability of their SCADA systems. This paper reports on our experience designing, architecting, and evaluating the first survivable SCADA system—one that is able to ensure correct behavior with minimal performance degradation even during cyber attacks that compromise part of the(More)
