Security professionals constantly face threats, but no one explains them in the way that Winn Schwartau does.

During a keynote at this year's SC Congress Canada in Toronto, the author and chairman of M@D Partners dove into the history of information security, citing both the successes and failures, leaning on his customary shoot-from-the-hip style. Schwartau says he likes to get the audience out of their comfort zone, which is necessary to solve today's complex security problems.

In this video Dan Kaplan, executive editor of SC Magazine, sits with Schwartau to discuss what exactly keeps him up at night as a security professional. And Schwartau is scared about a lot, from networked devices all the way to solar flares, but believes there is still time to institute changes. And it starts with the human factor.
