What is cybersecurity? How has cybersecurity become integrally connected to our national security? What has the War in Ukraine taught us about the vulnerabilities we face? What kinds of cyber threats should we be prepared to meet in the future?To discuss these questions, we are joined by Royal Hansen, Vice President of Engineering for Privacy, Safety, and Security at Google. As Hansen explains, cybersecurity can be understood as the safety, reliability, [and] availability of the technology that has transformed our lives in the past decades. Hansen argues that we have done reasonably well in securing the technologies we rely on. But as we are ever more reliant on technology, we increase our potential vulnerability to threats posed by rogue states and by criminals. To meet future challenges, Hansen advises us to think of cybersecurity as a dynamic and evolving process, in which both private companies and the government must do what is necessary to anticipate threats and maintain supremacy in technology.
