The security "unconference" is back in Vegas next week, and this time the setting is a gated private resort with multiple swimming pools and a sand beach, and the number of attendees signed up so far for the free -- yes, free -- event has doubled. But that doesn't mean Security BSides will lose the intimate vibe that its organizers envisioned and encouraged when they first launched it in Las Vegas a year ago. It won't be quite as cozy as last year, where there were about 40 to 100 people tops at one time at the smaller "hacker house" the BSides organizers rented. So far, there are close to 400 attendees expected for this year's event. But BSides won't pack hundreds of attendees in a room like Black Hat USA and Defcon, which are headlining the security conferences in Sin City next week, will. "There will still be plenty of rooms where you can continue the conversation," notes Jack Daniel, one of the founders and organizers of BSides. It's those side conversations that security folk thrive on, even at the bigger events.
