## Description

DARPA is working on additional pathways to support the transition of formal methods tools, including conducting a Resilient Software Systems Accelerator (RSS Accelerator). This accelerator will provide seed funding to formal methods tool developers who partner with Defense Industrial Base companies to identify Department of Defense (DoD) systems that would benefit from the use of their tools as described above.

DARPA funding would support an initial red team assessment of the DoD system’s vulnerabilities, the application of the formal methods tool(s), and a second red team assessment to measure impact and level of effort. Conclusions from the efficacy of the tool would be incorporated into the DARPA Guide to Formal Methods to Deliver Resilient Systems for Proposals (“the FMDRS Guide”).
