Today's cyberspace is a powerful, virtual environment enabled by our global digital infrastructure that provides a bright landscape for commerce, science, education, communication, and government. The future of America's prosperity hinges on rebalancing cyberspace to mitigate threats and maximize benefits, ensuring security and privacy in a constantly changing adversarial environment. Recognizing this great need, we requested original paper submissions in four general areas derived from the Federal Cybersecurity R&D program thrusts: Designed-In-Security (DIS) Builds the capability to design, develop, and evolve high-assurance, software-intensive systems predictably and reliably while effectively managing risk, cost, schedule, quality, and complexity. Tailored Trustworthy Spaces (TTS) Provides flexible, adaptive, distributed trust environments that can support functional and policy requirements arising from a wide spectrum of activities in the face of an evolving range of threats--recognizing the user's context and evolves as the context evolves. Moving Target (MT) Enables us to create, analyze, evaluate, and deploy mechanisms and strategies that are diverse and that continually shift and change over time to increase complexity and cost for attackers, limit the exposure of vulnerabilities and opportunities for attack, and increase system resiliency. Cyber Economic Incentives (CEI) Develops effective incentives to make cybersecurity ubiquitous, including incentives affecting individuals and organizations.
