Abstract	We are seeing a significant shift in the types and characteristics of computing devices that are commonly used. Today, more smartphones are sold than personal computers. An area of rapid growth are also cloud systems; and our everyday lives are invaded by sensors like smart meters and electronic tickets. The days when most computing resources were managed directly by a computer's operating system are over---data and computation is distributed, and devices are typically always connected via the Internet. In light of this shift, it is important to revisit the basic security properties we desire of computing systems and the mechanisms that we use to provide them. A building block of most of the security we enjoy in today's systems is access control. This panel will examine the challenges we face in adapting the access control models, techniques, and tools produced thus far to today's and tomorrow's computing environments. Key characteristics of these new systems that may require our approach to access control to change is that in many (e.g., cloud) systems users do not directly control their data; that a vast population of users operating mobile and other new devices has very little education in their use; and that cyber-physical systems permeate our environment to the point where they are often invisible to their users. Access control comprises enforcement systems, specification languages, and policy-management tools or approaches. In each of these areas the shifting computing landscape leaves us examining how current technology can be applied to new contexts or looking for new technology to fill the gap. Enforcement of access-control policy based on a trusted operating system, for example, does not cleanly translate to massively distributed, heterogeneous computing environments; to environments with many devices that are minimally administered or administered with minimal expertise; and to potentially untrusted clouds that hold sensitive data and computations that belong to entities other than the cloud owner. What technologies or system components should be the building blocks of enforcement in these settings?.
