GridEx IV pushes grid past 'breaking point'
In mid-November, Tim Yardley, associate director of technology at the Information Trust Institute (ITI), participated in GridEx IV, a biennial security exercise designed to simulate a cyber/physical attack on electric and other critical infrastructures across North America. Yardley's role involved helping to show what a GridEx-level event would look like on a digital replica of the grid. Yardley ran the dire GridEx scenarios through the ITI testbed, funded in part through the Defense Advanced Research Projects Agency (DARPA). The ITI testbed is also funded in part by the U.S. Department of Energy Office of Electricity and Energy Reliability (DOE-OE) and is used to support CREDC research efforts.
