Regional Resiliency Assessment Program Dependency Analysis Framework

The purpose of this report is to develop a common understanding and consistent analytic approach for evaluating critical infrastructure dependencies and interdependencies that will inform the programs of the U.S. Department of Homeland Security (DHS) Protective Security Coordination Division (PSCD). The framework outlined here prioritizes a need to tie together top-down and bottom-up analyses to produce a comprehensive “system of systems” view of dependencies and interdependencies that integrates the best available data. Examples of dependency and interdependency analyses from recent Regional Resiliency Assessment Program (RRAP) projects are included to illustrate practical applications of these concepts in support of infrastructure resilience.

Critical Infrastructure Interdependencies Assessment

Throughout the world there is strong recognition that critical infrastructure security and resilience needs to be improved. In the United States, the National Infrastructure Protection Plan (NIPP) provides the strategic vision to guide the national effort to manage risk to the Nation’s critical infrastructure.”1 The achievement of this vision is challenged by the complexity of critical infrastructure systems and their inherent interdependencies. The update to the NIPP presents an opportunity to advance the nation’s efforts to further understand and analyze interdependencies. Such an important undertaking requires the involvement of public and private sector stakeholders and the reinforcement of existing partnerships and collaborations within the U.S. Department of Homeland Security (DHS) and other Federal agencies, including national laboratories; State, local, tribal, and territorial governments; and nongovernmental organizations.

Analysis of Critical Infrastructure Dependencies and Interdependencies

The report begins by defining dependencies and interdependencies and exploring basic concepts of dependencies in order to facilitate a common understanding and consistent analytical approaches. Key concepts covered include; Characteristics of dependencies: upstream dependencies, internal dependencies, and downstream dependencies; Classes of dependencies: physical, cyber, geographic, and logical; and Dimensions of dependencies: operating environment, coupling and response behavior, type of failure, infrastructure characteristics, and state of operations From there, the report proposes a multi-phase roadmap to support dependency and interdependency assessment activities nationwide, identifying a range of data inputs, analysis activities, and potential products for each phase, as well as key steps needed to progress from one phase to the next. The report concludes by outlining a comprehensive, iterative, and scalable framework for analyzing dependencies and interdependencies that stakeholders can integrate into existing risk and resilience assessment efforts.
