Dynamical Network Models for Holistic Risk Management in Next-Generation 911 Systems

The Next-Generation 911 (NG911) initiative, which aims to update the United States' emergency communications systems to be Internet Protocol-based, should bring about profound benefits in system usability and resilience. However, there is great concern that NG911 systems will be highly vulnerable to cyber- risks, both because the increased accessibility provided by the system increases likelihood of intrusions, and because increased interconnectivity may amplify the consequence or impact of threats. The concern about cyber risks represents a significant barrier and cost in adoption of NG911, yet system stakeholders do Nt have tools available for systematically designing again risk at the planning stage, Nr for monitoring and mitigating actualized threats during operations. The purpose of this project is to develop quantitative risk assessment, monitoring, and mitigation techNlogies for the NG911 system, by developing dynamic network models and advanced analytics that enable risk management.
