The stereotypical view of computing, and hence computer security, is a landscape filled with laptops, desktops, smartphones and servers; general purpose computers in the proper sense. However, this is but the visible tip of the iceberg. In fact, most computing today is invisibly embedded into systems and environments that few of us would ever think of as computers. Indeed, applications in virtually all walks of modern life, from automobiles to medical devices, power grids to voting machines, have evolved to rely on the same substrate of general purpose microprocessors and (frequently) network connectivity that underlie our personal computers. Yet along with the power of these capabilities come the same potential risks as well. My research has focused on understanding the scope of such problems by exploring vulnerabilities in the embedded environment, how they arise, and the shape of the attack surfaces they expose. In this talk, I will particularly discuss recent work on two large-scale platforms: modern automobiles and electronic voting machines. In each case, I will explain how implicit or explicit assumptions in the design of the systems have opened them to attack. I will demonstrate these problems, concretely and completely, including arbitrary control over election results and remote tracking and control of an unmodified automobile. I will explain the nature of these problems, how they have come to arise, and the challenges in hardening such systems going forward.
Bio: Stephen Checkoway is a Ph.D. candidate in Computer Science and Engineering at UC San Diego. Before that he received his B.S. from the University of Washington. He is also a member of the Center for Automotive Embedded Systems Security, a collaboration between UC San Diego and the University of Washington. Checkoway’s research spans a range of applied security problems including the security of embedded and cyber-physical systems, electronic voting, and memory safety vulnerabilities.
