Caleb Davis & Nathan Smith

Making a Sick Badge

This year we created our first DEF CON badge and enjoyed almost every second of it. In this presentation we hope to enable other security professionals to tinker with badge development and give them tools and tricks to help facilitate their creativity. We think that understanding the process to create a working thing helps us all better understand where we can do things more securely and how to break things better. We will review the boring and unavoidable design questions that must be addressed, the exhilarating process of creating something that works well, and scaling up from a working prototype. We will demonstrate using real steps we took this year to make our badge for the Biohacking Village.
