The security measures this year at the Sun Valley, Idaho, Allen & Co. media conference are tighter than ever before. The staff at the Sun Valley Inn are also concerned about drones above.

The Sun Valley conference reportedly blocked off large portions of the resort to people who weren't invited to the exclusive event where media and tech moguls wheel and deal. One of the pools is reportedly closed, as is the Duchin bar during the evening. The lobby was also reported to be closed.

Another report highlights the extent to which security measures have been taken to secure the event from the public, or from would-be intruders.

Event staff at the Sun Valley Inn are keeping their eyes in the skies scouting for drones and remote aerial vehicles, likely armed with cameras to take photos of moguls like Google's Eric Schmidt to sell to news agencies.

This year, Facebook CEO Mark Zuckerberg will reportedly be at the conference. So will AOL's own Tim Armstrong. Other notable guests include LinkedIn's Jeff Weiner, Twitter's Dick Costolo, Greylock Partners venture capitalist Reid Hoffman and Amazon's Jeff Bezos.

Nonauthorized press aren't even allowed a glimpse of these industry leaders.

Commercial use of drone vehicles is technically against the law, according to the U.S. Federal Aviation Adminstration. Congress is working on changes to the law in regard to aerial vehicles under 55 pounds.

"You cannot operate any aircraft in a way that endangers the safety of people and property on the ground," FAA spokesperson Les Dorr told the press. "If you're buzzing over people, we could take enforcement action."
