Cybersecurity: Risk, Defense & Recovery
How attacks on computers and networks happen, what they cost, and how households and organizations prevent them, find them, and recover from them, as of October 2026: risk and the NIST framework's six functions; who attacks and how an intrusion unfolds; passwords, multifactor authentication, and passkeys; software flaws and patching; scams and fraud, from business email to the scam compounds; ransomware and extortion; suppliers, open-source software, and the cloud; water, power, and hospitals; what states do in cyberspace, from the Iran war to China's Typhoon campaigns; AI on both sides; detection, response, and the reporting deadlines; backups and rebuilding; cyber insurance and the war exclusion; the law in America, Europe, and Britain; and privacy and data brokers. Where the field argues, each side's case comes before the course's reading. Two worked examples run through it, a household whose accounts are taken over and a manufacturer recovering from ransomware. Opens with a dated table of key measures, the state of the art, a Who's Who, and a list of terms.** **
