Note from the editor

A first-ever cyberattack against U.S. wind and solar assets in 2019 opened a new front in the ongoing battle to ensure the security of the nation's power grid.

More recent incidents involving multinational energy company Enel as well as a natural gas compressor station also show a growing threat to the energy sector.

To reduce the risks, companies are examining their security culture and turning to new approaches like machine learning, while the Trump Administration is working to address threats from China, Russia and other countries.

The following trendline examines various threats, responses and challenges in the ever expanding "cat and mouse game" of cybersecurity.
