Every January about 2,500 attendees flock to the World Economic Forum in Davos-Klosters, Switzerland—a country known for its mountains, banks, chocolates and watches—to explore the trends and opportunities pushing global, regional and industry transformation. As expected, the participants are greeted with beautiful scenery, lots of snow, friendly locals—and, of course, a plethora of security. The reason: Among those participating are some of the world's most influential business, political, and intellectual leaders of our time.
From snipers on rooftops to checkpoints run by the Swiss Army, security is taken extremely seriously in and around this small town of just 11,000 residents. And according to Edward Stroz, the executive chairman of Stroz Friedberg—a firm based in New York City that offers global solutions and services to address investigative, intelligence and risk-management challenges—it needs to be. The former FBI agent told CNBC that this annual five-day global meeting is a prime target.
"Anytime you have the chance to answer the questions of who, when, where, why and how, you give an adversary or any kind of threat agent an advantage." At the World Economic Forum all of those factors are in place, he said, from the central location, to the time, to the list of attendees. Stroz, however, warned: One of the biggest risks may be what most people won't expect—one that, despite all of the visible security, may be difficult to prevent.
