After recent attacks threw the rampant insecurities of internet-connected cameras, video recorders, and other gadgets into sharp relief, Washington lawmakers and officials are urging tech firms to do more to secure the Internet of Things. At a House Energy and Commerce subcommittee hearing last month, lawmakers said the attacks raised national security concerns and questions about the need for government intervention. “We are in this sorry and deteriorating state because there’s almost no cost for a manufacturer to deploy products with poor cybersecurity,” says Kevin Fu, associate professor in electrical engineering and computer science, who was an expert witness at the hearing. “In the long term, it’s going to take sustained support from government, industry, and universities to get security built into the billions of emerging IoT devices.”
