National Security Sciences
Our multi-disciplinary teams are passionate about creating science-based solutions to complex security threats that put public safety, national defense, energy infrastructure, and the economy at risk. By joining with us, you gain the opportunity to be at the forefront of solving some of the most critical national security challenges facing our nation.
About the National Security Sciences Directorate
The National Security Sciences Directorate (NSSD) leads scientific and technological breakthroughs to confront some of the nation’s most difficult security challenges. We develop applications needed for the security of our nation today and target our vision on how these challenges may manifest themselves in a decade or more.
NSSD focuses on cybersecurity and cyber physical resiliency, data analytics, geospatial science and technology, nuclear nonproliferation, and high-performance computing for sensitive national security missions. We also enhance ORNL contributions to national security challenges by working closely with leading researchers at the lab in areas such as nuclear and chemical sciences and engineering, applied materials, advanced manufacturing, biosecurity, transportation, and computing.
CYBER PHYSICAL LABORATORY
Inside ORNL’s Cyber Physical Laboratory (CPL), multi-disciplinary teams join together to innovate technologies, processes, and data analysis methods to ensure the resilience and security of critical infrastructure. These cybersecurity researchers, computer scientists, engineers, and mathematicians work together to advance the security of cyber physical systems by characterizing adversaries and security risks and developing mitigations for dynamic cyber threats. The CPL and the work of these teams is creating groundbreaking digital twin technology, advanced forensics, and automated vulnerability mapping capabilities for enhancing the security and resilience of the electric grid, transportation systems, manufacturing systems, and the nation’s fastest supercomputer, Summit.
The National Security Sciences Directorate is home to scientific leadership in three critical areas:
The Cyber Resilience and Intelligence Division enhances national security by advancing the resilience and security of critical cyber infrastructure, innovating advanced sensing and analytic ecosystems to characterize adversaries and security risks, and developing mitigations for dynamic cyber threats. To achieve this mission the team leverages multidisciplinary capabilities such as cybersecurity, computer/data science, engineering, and mathematics. We focus our research in two sections: Adversary Intelligence Systems and Resilient Complex Systems.
The Nuclear Nonproliferation Division supports nonproliferation
and security missions of the National Nuclear Security
Administration, including development and implementation of technologies; engagements to strengthen nonproliferation regimes;
and research and development to detect and monitor foreign
nuclear fuel cycle and weapons development activities, movement or diversion of special nuclear material, and nuclear explosions. Our major research sections include Nuclear and Radiological Security, Proliferation Detection and Deterrence, Safeguards and Treaty Verification, and Mission Management Systems.
The Geospatial Science & Human Security Division performs interdisciplinary research on how we observe, analyze, and visualize landscape and human dynamics. Utilizing data and computing at unprecedented scale, we shed light, often in near real-time, on critical situations arising from geopolitical instabilities, natural disasters, resource scarcities, and health crises that impact human safety and security.
In addition, NSSD’s National Security Programs work closely with researchers across the lab in nuclear and chemical sciences and engineering, applied materials, advanced manufacturing, biosecurity, transportation, and computing.
Securing the Nation
Over the 75-year history of Oak Ridge National Laboratory, we have established global leadership in the sciences and technologies that underpin nuclear nonproliferation, counterproliferation, and counterterrorism. More recently we have pioneered applications based on geospatial sciences, cybersecurity, data analytics, advanced manufacturing, energy systems, and materials science to meet critical national security needs. We now seek to broaden our competencies in areas that include 5G mobile network technology, data privacy research, bias prevention in modeling, and software vulnerability science.
