The Department of Defense (DOD) is seeking proposals for User and Entity Behavior Analysis (UEBA) as part of their Small Business Innovation Research (SBIR) program. The objective of this solicitation is to develop a UEBA capability that will streamline authentication to the network and services while enhancing the cybersecurity posture of the tactical network. The UEBA solution will serve as a critical enabler to the Army's Zero Trust Architecture (ZTA) implementation. The technology will leverage data already collected and normalized by the Elastic Stack, including data from various systems and events. The UEBA should include a well-documented and flexible REST API for obtaining necessary telemetry for authorization decisions. The project will be conducted in two phases, starting with a proof of concept in Phase I and the development of a prototype in Phase II. The potential applications of UEBA include IoT monitoring, healthcare security, and finance fraud detection. The solicitation is open until March 31, 2025.
