Critical Infrastructures (CIs) such as power grid, water and gas distribution\nare controlled by Industrial Control Systems (ICS). Sensors and actuators of a\nphysical plant are managed by the ICS. Data and commands transmitted over the\nnetwork from the Programmable Logic Controllers (PLCs) are saved and parsed\nwithin the Historian. Generally, this architecture guarantees to check for any\nprocess anomalies that may occur due to component failures and cyber attacks.\nThe other use of this data allows activities such as forensic analysis. To\nsecure the network is also crucial to protect the communication between\ndevices. A cyber attack on the log devices could jeopardize any forensic\nanalysis be it for maintenance, or discovering an attack trail. In this paper\nis proposed a strategy to secure plant operational data recorded in the\nHistorian and data exchange in the network. An integrity checking mechanism, in\ncombination with blockchain, is used to ensure data integrity. Data redundancy\nis achieved by applying an efficient replication mechanism and enables data\nrecovery after an attack.\n
