Professors supporting DHS vulnerability management, risk modeling and analytics


Paulo Costa, Associate Professor, Cyber Security Engineering/Systems Engineering and Operations Research (CYSE/SEOR), Peggy Brouse, Professor, (CYSE/SEOR), and Duminda Wijesekera, Professor and Chair, Cyber Security Engineering (CYSE), are working with the U.S. Department of Homeland Security (DHS). The researchers are conducting work as part of a partnership focused on an operational pilot that will implement isolation architecture to gather incident rate data in the context of Mason’s operational environment, and isolation architecture effectiveness data from that operational environment. Coupled with the Cybersecurity and Infrastructure Security Agency (CISA) Office of the Chief Economist’s (OCE) analysis of cost per incident, this operational test data will be used by the Cyber Security Division (CSD) to derive technical efficiency and cost effectiveness of the isolation architecture and scale it to the Federal Civilian Executive Branch (FCEB).

The researchers received $48,000 from DHS for this project. Funding began in January 2021and will end in April 2021.
