Cybersecurity is usually discussed as a threat to our personal or organizational finances. Credit card fraud, online scams, and intellectual property theft are easy money for cybercriminals, who are unlikely to face legal consequences. Likewise, cyberespionage is a relatively easy and low-cost way for nation states to acquire high-value intelligence. There is relatively little discussion on the risks of cyberattacks on physical infrastructure or the growing role of cybercrime in the operation and funding of terrorist groups—but the dangers are real and growing.
