The present invention generally relates to network-attack-resilient intrusion-tolerant Supervisory Control and Data Acquisition (SCADA) systems. Some implementations utilize redundant, proactively-recovery-configured servers at multiple centers communally executing a replication protocol. Some implementations, in addition to control centers, include data centers, which participate in the replication protocol, except that they may not be capable of controlling remote units such as Remote Terminal Units (RTUs).

Network-attack-resilient intrusion-tolerant SCADA architecture

Systems, computer readable media, and method concern assigning an abstraction representation to data associated with a system of the SCADA environment. The method also includes providing the abstraction representation to a control system associated with the system of the SCADA environment. The control system is implemented in a computer system. Further, the method includes receiving actual data from the system of the SCADA environment. Additionally, the method includes generating abstract data from the actual data using the abstraction representation. The method, also includes forwarding the abstract data to the control system.
