One of the key findings of the August 2003 Northeast Blackout was the need to modernize the electric grid. Upgrading older, less reliable electromechanical switches (cyber dumb) with highly reliable modern Intelligent Electronic Devices - IEDs (cyber vulnerable) was a cornerstone of this approach. The grid is certainly more reliable but much more cyber vulnerable because of these upgrades. The Aurora demonstration by the Idaho National Laboratory caused physical destruction of a diesel generator by exploiting the IED cyber vulnerabilities.
