Terrorism Prevention

The Science and Technology Directorate (S&T) supports the Department of Homeland Security (DHS) terrorism prevention mission by conducting applied research, evaluation, and integrating scientifically derived knowledge to inform policy and programs throughout the Homeland Security Enterprise.

What terrorism prevention resources does S&T offer?

In conjunction with the Office for Targeted Violence and Terrorism Prevention, S&T develops wide-ranging resources for government and local partners to (a) support our understanding of individual motives for engaging in, and disengaging from violent extremism, (b) develop and assist locally-tailored interventions with local partners, and (c) evaluate the effectiveness of terrorism prevention activities and policies.

  • Research products
    Wide ranging evidence-based products from projects designed to build foundational knowledge of the nature of the threat, and effective responses.
  • Fact sheets
    Provide key information about issues relevant to terrorism prevention for government, law enforcement, local communities, stakeholders, international partners and more.
  • Evaluations
    Rigorous evaluations of terrorism prevention programs and policies across the Homeland Security Enterprise using behavioral and social science methodologies.

S&T also transitions, to the public, data tools that provide insights into violent extremism. These resources focus on three areas:

S&T Develops Terrorism Prevention Research Findings Dashboard
Sept. 28, 2018 -- To counter the continually growing and changing threat of violent extremism, DHS S&T has developed a free and publicly accessible research findings dashboard that hosts more than 1,500 cataloged terrorism prevention and countering violent extremism research documents. This dashboard is an agile, multi‑disciplinary knowledge‑based capability that helps to systematically develop a landscape of the existing research in this topic area across multiple disciplines, including social and behavioral science.

S&T Develops the First Line of Defense Against Acts of Targeted Violence
Aug. 28, 2018 -- Since 2010, the U.S. government has invested more than $20 million into understanding all forms of radicalization to violence, as well as effective prevention and intervention measures.

Understanding Engagement in Violent Extremism

Operational Research Roadmap

Engage stakeholders to understand how organizations:

  1. Define their terrorism prevention mission
  2. Decide what actions to undertake
  3. Interact with other stakeholders

International Expert Engagement

Engage international experts to share terrorism prevention best practices and to guide the development and implementation of safe and effective programs. Domestic government agencies and law enforcement organizations from Australia, Canada, New Zealand, the United Kingdom, and the United States have agreed to exchange information and coordinate applied research efforts under the framework of the Five Country Research & Development Network (5RD).

Developing Local Terrorism Prevention Capabilities

Risk Assessment Tools to Support Secondary and Tertiary Interventions of Violent Extremism

Engaging stakeholders to understand whether and how individual risk assessments are currently performed, perceptions of such tools, and recommendations for the creation and implementation of successful individual assessment tools.

Text-Enabled Safe Referral Call Center Protocols & Evaluation

S&T is filling a gap by funding the creation of protocols for safe-referral systems for friends, family, and other influencers to connect individuals with social service resources. Through coordination from the Office for Terrorism Prevention Partnerships (OTPP), S&T performers have identified a domestic crisis hotline center to partner with for pilot testing of the protocols.

Evaluating Terrorism Prevention Programs and Interventions

Program Evaluations in Boston and Los Angeles

Program evaluations in cities with terrorism prevention programs aim to increase understanding of needs, awareness of community-based interventions for reducing violent extremism, and the understanding of metrics to determine the impact of the program. Findings on scalability and sustainability will be delivered to:

  • Practitioners
  • Social and community service agencies
  • National policymakers
