Biden's new policy is largely a rewrite of the Obama administration's rule to safeguard U.S. critical infrastructure called the Presidential Policy Directive, or PPD-21, which was published in 2013. The effort to redraft that Obama-era infrastructure policy began over a year ago, in part to modernize it and keep up with hackers who have benefited from over a decade of technological advancement. The Biden administration has warned China not to help Russia in its invasion of Ukraine, or else the U.S. would be ready to act with sanctions. "We're aware now of the serious Chinese threat to our critical infrastructure, specifically prepositioning to disrupt or destroy critical infrastructure in the event of a major crisis," a senior administration official said. "The presidential policy directive that was created in 2013 didn't mention anything about CISA's role because we weren't created yet," a senior administration official said.
