As a technologist you craft systems that are reliable, scalable, and maintainable. As a security specialist you think adversarially and poke holes in every apparatus you encounter, be it technical, social, or socio-technical. These skills are orthogonal to the ones that good user-experience (UX) designers employ in making software that is usable by “average” people, which is probably why so many security tools suck. In this talk you’ll see why your approach to designing software interfaces is broken, get a window into how professionals would make it better, and learn scrappy techniques that even the most awkward infosec nerd can use to make their software suck less for real users.
