The Trump administration on Wednesday issued an executive order banning the acquisition of foreign-made technology used to manage electricity and power.

The White House said the decision was made because “certain foreign actors are increasingly creating and exploiting vulnerabilities” in the technology — known as bulk-power systems. 

The order warns that the equipment powering critical infrastructure may have digital backdoors allowing foreign governments to access equipment remotely or cause supply-chain disruptions.

“During my first term, I found that the bulk-power system could be a target of those seeking to commit malicious acts against the United States, including malicious cyber activities, because of the significant risks that a successful attack would have on our economy, human health and safety, and national defense,” President Donald Trump said.
