  • Resilient PNT Standard IEEE Conformity Assessment Program Fact Sheet

    The IEEE Conformity Assessment Program (ICAP) provides the technical means to verify standard compliance and credibility for CI end users.

  • Addressing the Nation's Wildfire Problem: An S&T Roadmap

    As climate conditions are becoming hotter and drier, wildfires have grown more intense and destructive across much of the United States. The public safety challenges from wildfires are most acute in the area known as the wildland urban interface where lives and infrastructure are at most risk. Addressing the nation’s wildfire problem will invariably involve bridging different cultures of fire safety and risk that have traditionally been separate and developing a mix of social and technological innovations and ecosystem services to enable better wildfire mitigation and firefighting practices.

  • Department of Homeland Security Core Ontology for Maritime Domain Awareness Fact Sheet

    The objective of the Department of Homeland Security (DHS) Core Ontology for Maritime Domain Awareness effort is to provide DHS with the base of a semantic framework, in the form of a DHS Core Ontology, a Maritime Domain Awareness Ontology, and a Computational Analytic Ontology. ​The semantic framework will be an evolving part of the DHS data architecture enabling the functionality to create data that is integrated, familiar and trusted.​ The base framework will enable evolution by having a core ontology of DHS terms which are then reused to create interoperable ontologies covering the numerous and diverse domains of interest to DHS.

  • Earth Systems Science: Key Themes, Trends, and Emerging Concerns

    Our Earth system is facing a multitude of challenges across a variety of threat vectors. Identifying, characterizing, quantifying, and addressing these risks remains difficult. Threats like climate change pose existential risks but are not well understood from an integrated systems and safety and security perspective. This paper will cover a few themes that should drive our thinking and research agenda on resilience, disaster preparedness, and climate change and be factored into our calculus going forward.

  • Extreme Weather: Opportunities for Improved Preparedness and Resilience

    This report is built on a DHS Science and Technology and National Oceanic and Atmospheric Administration joint workshop hosted at the University of Oklahoma National Weather Center in February 2024 to examine policy, mission, science, and technology requirements to support homeland security, emergency management and public safety missions in the face of extreme weather.

  • Emergency Management of Tomorrow Research: Emergency Operations Center of the Future Tabletop Exercises

    DHS S&T partnered with Pacific Northwest National Laboratory (PNNL) on the Emergency Management of Tomorrow Research (EMOTR) program. PNNL hosted three tabletop exercises (TTX) to develop concepts for the Emergency Operations Center (EOC) of the Future and provide recommendations to assist DHS S&T in future decision-making with regards to research and development (R&D) and investments toward establishing a framework for a national, coordinated approach to EM.

  • GPS Equipment Testing for Critical Infrastructure Fact Sheet

    The GPS Equipment Testing for Critical Infrastructure (GET-CI) test series is part of the Science and Technology Directorate's Positioning, Navigation, and Timing Program's collaborative efforts designed to help industry partners test and evaluate their technologies to become more resilient against disruptions.
