The security delusion - Bruce Schneier - TED-Ed

What this episode covers

The feeling of security and the reality of security don't always match, says computer-security expert Bruce Schneier. In his talk, he explains why we spend billions addressing news story risks, like the "security theater" now playing at your local airport, while neglecting more probable risks -- and how we can break this pattern.
