Industrial Control Systems (ICS) are jeopardized from a large set of threat vectors, which exploit their vulnerabilities in order to impact the physical Critical Infrastructures they control. The Information Technology (IT) classical approach to cyber attacks can not be applied to ICS due to their extreme differences from main priorities to resource constrains. Therefore, innovative approaches and equipment must be developed in order to suit with ICS world. In this paper, a Smart Behavioural Filter (SBF) for the PLCs/RTUs is proposed aiming to secure the PLC/RTU itself against logic attacks, that are stealth for other more classical security approaches. Those logic attacks are usually anomaly behaviours, for instance a large number of open/close commands towards a valve. This smart field equipment can communicate with other equipment like itself in order to react in short time to cyber attacks and increase the resilience of the physical system. It can also generate alarms for the local Intrusion Detection System (IDS) The proposed equipment has been developed and validated in a real test-bed within the FP7 CockpitCI project. The results are promising.
