Abstract: This paper presents a system concept for integrating the mass of information critical to infrastructure protection operations. Our main focus and contribution lies in (1) coupling risk assessments into a dynamic decision support process, and (2) providing a collaboration and visualization decision support interface for representing complex and changing infrastructure protection information. The system concept supports adaptive decision making based upon dynamic risk and readiness assessments. Users benefit from having a more comprehensive and up-to-date risk picture on which to base their judgments.
