The present paper provides a comprehensive review about the main concepts on situation awareness for critical infrastructure. The issues related to models and architectures for data fusion and situation awareness are reported in the framework of Critical Infrastructure Protection. Both data fusion and situation swareness have been developed in Critical Infrastructure field to merge and integrate data from several heterogeneous sensors. Since Critical Infrastructures are interconnected, the integration of sensor data is mandatory to avoid or mitigate risk of cascading and domino effects. This integration requires the cooperative signal processing of a federation of critical infrastructures.
