To be most effective, the NCDC should be placed in the Office of the National Cyber Director (ONCD), which was established by Congress in late 2020 as a new element of the Executive Office of the President. Serious and Growing Cyber Threats to US National Security Both state and nonstate adversaries are conducting sustained cyber-enabled campaigns that aim to advance those adversaries’ interests and undermine the interests of the United States. The fabric of American society and the US political system are under attack in cyberspace, as Russia and other countries are conducting cyber-enabled disinformation attacks to sow domestic discord and undermine democracy in the United States. China’s cyber-enabled theft of US intellectual property has been estimated to cost the United States 1–2 percent of its gross domestic product annually. The US government and private sector are also vulnerable to disruptive and destructive cyber attacks, as exemplified by Iran’s distributed denial-of-service (DDoS) attacks on Wall Street from 2012 to 2013 and North Korea’s 2014 cyber attack on Sony Entertainment and its WannaCry ransomware attacks of 2017. Cyber crime costs US firms hundreds of billions of dollars per year; cyber ransomware attacks threaten business operations, and those targeting the health care industry have disrupted hospitals and put patients at risk. The failure to stem cyber intrusions, as exemplified by Russia’s massive SolarWinds hack discovered in late 2020 and the hack of Microsoft Exchange discovered in early 2021 (and attributed by many to China), poses incalculable risks to American security. In addition to the day-to-day challenges from malicious cyber activity below
