synERGY: Detecting Advanced Attacks Across Multiple Layers of Cyber-Physical Systems.

Today's security solutions usually address only single architectural layers, and are unable to take account of the full picture. This leads to a system operator having only a limited view regarding the root cause of a cyberattack, which can reduce the overall availability of cyber-physical systems (CPS). Particularly for complex and stealthy multi-stage attacks, an approach is required that correlates information from all CPS layers, including the field area, the SCADA backend, the enterprise IT and the WAN (in the case of large-scale CPS) to promptly react to emerging malicious activities.
