In a new book, Janet Napolitano, the former head of the Department of Homeland Security, says it is “impossible to overstate the urgency of improving our country's cybersecurity.” She says we're vulnerable all over the place, from critical infrastructure like utilities and 911 dispatch systems to our elections and our personal data. But there are lots of federal agencies in charge of it, and they have to work with lots of private companies to address it.
Host Molly Wood spoke with Napolitano about her new book “How Safe Are We? Homeland Security Since 9/11.” She asked her what she wishes her agency had done differently. The following is an edited transcript of their conversation.
