The Missile Defense Agency (MDA) is seeking proposals for the development of autonomous tools aimed at passive vulnerability screening of systems outside its accreditation boundary. The primary objective is to identify externally reachable vulnerabilities in software relevant to military operations, utilizing an innovative approach that combines automated software fuzzing with passive cyber risk sensing techniques. This initiative is critical for enhancing the security posture of military networks and systems, as it addresses current limitations in vulnerability detection methods. Proposals for Phase II are due by February 5, 2025, with the opportunity expected to open on January 8, 2025. Interested parties can find more information and submit proposals through the official solicitation portal at dodsbirsttr.mil.
