Reuben A. Paul, aka RAPstar, has something of a head-start when it comes to learning about computer security: his father, Mano Paul, has been a security researcher (and instructor) for many years. So Reuben grew up around computers, seeing firsthand that they're neither mysterious nor impregnable. Reuben, though, has a curious mind and his own computer security interests, and a knack for telling others about them; last month, he became the youngest-ever speaker at DerbyCon, and explained some of what he's picked up so far on what kids can learn about security, as well as what the security field can learn from kids. (One hard to dispute nugget: "Kids are the best social engineers, followed by puppies.") Ask of Reuben whatever you'd like, below (please, one question per post), and we'll get answers to selected questions when we catch up with him at next week's Houston Security Conference. (This year's conference is sold out, but there's always 2015.)
