The release of toxic materials in a subway could result in widespread contamination of the system. To counter this threat, Sandia has developed and tested a method for containment and neutralization of highly toxic materials. Charged sprays of a mild decontamination chemistry are introduced to the cloud of material, knocking it to the ground and neutralizing it. The approach has been demonstrated for biological pathogens, liquid aerosols of chemical materials, and vapors in a test chamber at Sandia and in a mock subway system (photo at right) during a DHS demonstration.

NCRT leverages a rigorous methodology that originated with the Lab’s mission to ensure a safe and reliable nuclear stockpile.

Critical federal networks are under constant cyber attack from malicious actors looking to undermine our nation’s security. Sandia’s National Security Cyber Red Team’s (NCRT) job is to assess vulnerabilities in key DHS systems responsible for the defense of government networks. To detect and mitigate vulnerabilities, NCRT has performed multiple cybersecurity assessments using a rigorous methodology that originated with Sandia’s mission to ensure a safe and reliable nuclear stockpile. The NCRT methodology has been developed and refined through decades of experience on cyber and cyber-physical systems. (6600, 5600, 8900)
