When asked what his father did for a living, my son explained to his kindergarten teacher that "he steals things, but it's OK because he gets paid to do it".
He wasn't wrong. I'm a hacker, and I run a team of hackers. We spend our days discovering ways to break into anything that can connect to the Internet - servers, automated teller machines, light bulbs, for example - in an attempt to access information that was never meant to be seen. If we get to it before a criminal does, then we've done our job.
