As our lives become increasingly tech driven, we’re more vulnerable to cyberattacks, and our workplaces and government are too. William Evanina, director of the National Counterintelligence and Security Center (NCSC), says it takes a whole-of-nation counterintelligence and security effort to keep our data safe. His organization is helping lead the charge. In this episode, he talks with NPR counter-terrorism correspondent Dina Temple-Raston about why Americans easily fall prey to spear phishing attacks and how our personal information, through gadgets like baby monitors, can easily be collected. They also discuss potential Russian interference in the midterm elections, Edward Snowden, government background checks, and technology and the US supply chain.
