Jack Goldsmith is a professor of law at Harvard University and served as Assistant Attorney General in the Office of Legal Counsel (2003-2004). In this Conversation, Goldsmith shares his perspective on America’s vulnerabilities to cyber attack—the complex and systemic threats to our digital and physical infrastructures, as well as to our politics via hacking and digital espionage. As Goldsmith explains, we have not done nearly enough to counter cyber threats through better defense or employment of countermeasures against adversaries. Finally, Kristol and Goldsmith consider what the government and private sector can do to improve our cybersecurity.
