The most interesting thing about Black Hat 2015 keynote speaker Jennifer Granick isn't her gender -- though she appears against a backdrop of historically male keynotes. It's that Granick is director of civil liberties at the Stanford Center for Internet and Society. She previously held the same position at the Electronic Frontier Foundation -- and is known for defending some of the more notorious criminal hackers around, including Kevin Poulsen, Aaron Swartz, Jerome Heckenkamp and the hackers in the Diebold Election Systems case. Being the keynote speaker at the Black Hat conference means she's about to go front and center with the very organizations and government entities her clients have hacked. Granick is joining a colorful catalog of former keynoters who tend to represent the interests of the international cybersecurity conference's corporate-enterprise and government attendees.
