The Cybersecurity and Infrastructure Security Agency (CISA) leads the national effort to understand, manage, and reduce risk to our cyber and physical infrastructure. CISA must assess risks that cover a broad range of scenarios over a complex set of interdependent critical infrastructure (CI) systems. While many threat and hazard impact models and data sets exist, there is no overarching analytic structure that organizes and integrates these disparate sources into a unified risk assessment. CISA is building capabilities that will address these challenges to support stakeholders across all levels of government and the private sector. 

First, CISA has developed a National Critical Functions (NCFs) data structure to organize and describe critical infrastructure. This data set provides a set of decompositions structured as directed graphs that break down each identified function into enabling sub-functions that detail the operation and interdependencies across disparate CI systems.  The functional description of NCFs serves as a complementary lens to the sector-based organization of CI and better facilitates systemic and cross-sector risk analysis. 

Cyrus Jian Bonyadi is a PhD student working on developing a set of corollaries for consensus theory in distributed system security. Cyrus is a former member of the UMBC Cyberdawgs cyberdefense team and maintains a relationship with UMBC as a full time researcher at Sandia National Labs. 

Host: Alan T. Sherman, sherman@umbc.edu. Support for this event was provided in part by the National Science Foundation under SFS grant DGE-1753681.  The UMBC Cyber Defense Lab meets biweekly Fridays 12-1pm.
