This week is hacker week in Las Vegas. The desert playground is hosting three conferences dedicated to computer security - Black Hat USA, Def Con and B-sides LV.
Between them, they capture the entire gamut of hacker culture.
Black Hat is the sensible, grown-up conference, where the clothes might be casual but the shoes are shiny. B-sides is an unofficial companion conference for Black Hat and acts as a fringe event for the bigger show. Def Con is their freewheeling, raucous, free-spirited sibling. With tattoos. And a Mohawk.
Black Hat is now the biggest gathering of security professionals in the world and about 8,000 people involved in computer security will attend its training sessions, briefings and seminars.
But what do they all do? What is a typical day as a security professional actually like?
