The capabilities, frequency, and severity of global attacks on critical infrastructure has increased since then as control systems have evolved and become increasingly connected. The traditional approach of perimeter hardening by physically separating control systems and outside communications infrastructure is no longer adequate. Today’s interconnected control systems, have the potential to exchange information across the globe. These Industrial Internet systems require comprehensive cyber security capabilities to meet evolving cyber security threats. In this paper, we will highlight the seven strategies described by DHS to counter common exploitable weaknesses in industrial control systems. We will also examine GE’s Defense- In-Depth approach to cyber security, applying cyber defense capabilities at every level of product implementation, and how it helps to protect customers using our Industrial Internet Control System.
