How to protect the power grid from low-budget cyberattacks

Cyberattacks against power grids and other critical infrastructure systems have long been considered a threat limited to nation-states due to the sophistication and resources necessary to mount them. … Michail Maniatakos, a research professor at the NYU Tandon School of Engineering and an assistant professor of electrical and computer engineering at NYU Abu Dhabi, detailed the discovery of a security flaw in the authentication mechanism of a legacy protective relay — a component that responds to changes in flow across the grid to isolate electrical faults.
