This year when U.S. Cyber Command convened with allied countries to test how they would collectively defend against a cyber-operation targeting allied networks, the units came together for what appeared to be a straightforward simulation of an attack against a European airbase.
The worldwide coronavirus pandemic made the simulation less than straightforward.
For the first time ever, participants conducted the exercise from home on a new platform, according to U.S. military cyber commanders involved in the exercise. The annual simulation, which simulated an attack that impacted both information technology (IT) and operational technology (OT), took place on the Persistent Cyber Training Environment (PCTE).
