A national study on electric grid security called on the United States to do more to protect its grid against high-impact attacks.

With growing risks to the nation's electrical grid from natural disasters and as a potential target for malicious attacks, the U.S. Department of Energy (DOE) and the U.S. Department of Homeland Security (DHS) should work closely with utility operators and other stakeholders to improve cyber and physical security and resilience, said the report, which was from a new congressionally mandated report by the National Academies of Sciences, Engineering, and Medicine.
