Two premiere security conferences, Black Hat and DefCon, run back-to-back in Las Vegas this week, each with their own distinct flavor. But even these events don't meet the needs of all computer security pros, setting the stage for a widening set of satellite events. Jack Daniel, community development manager for Astaro, says he's getting to town a day early specifically for a four-and-a-half hour conference run by security vendor Codenomicon, then sitting on a panel at Security B-Sides, which directly competes with Black Hat, then speaking at DefCon. That wealth of content in one city at one time is a big draw. "It's a reason to get to Vegas this week if you can afford it," Daniel says.
