Massive global events like the Olympics are a magnet for cybercriminals and hacktivists. There are incredible complex systems to disrupt, billions in digital dollars moving around and the eyes of the world's media are watching for any logistical failure. But much like intelligence services coordinate to prevent physical terrorism, there's a network of cybersecurity units from nations around the world doing the same thing in the digital space.

So how do you keep the Olympics secure, digitally? Where are the vulnerabilities in this type of event? What do organizations like the IOC or even ordinary citizens following the games need to know about the risks? We're talking to the folks that do this work for Canada to try to stay ahead in a rapid technological arms race.
