ACSAC is renewing its focus on tackling hard, cutting-edge, cyber security problems requiring cooperation from government, industry and academia. A track of orchestrated sessions will include government and industry speakers to frame the problem, industry and academic speakers to discuss issues and challenges related to the problem, and academic speakers to introduce promising security research. We will also address failed attempts that provide useful lessons learned. The primary goal of this special track will be to foster discussion that can expose opportunities for further collaboration and highlight promising research directions. For 2014, ACSAC continues with Cybersecurity for Cyber-Physical Systems for its hard topic theme. From a safety perspective, such systems have undergone extensive study; their proliferation now motivates focused research from a security perspective.
