Defense Operations Security Initiative (DOSI)

Abstract

This program supports the National Strategy and Department's priorities to Deter Aggression, Defend the Homeland, Prevail in Conflict, and Build Sustainable and Long-Term Advantage. This program also supports DoD Data Strategy, specifically enabling next-generation approaches to protect data as it is a strategic asset. The Defense Operations Security Initiative (DOSI) establishes and leads the Department's next-generation Operations Security (OPSEC) capability development and affiliated investment strategy. Investments support DoD's current and emerging OPSEC capability gaps, including countering advances in non-U.S. Intelligence, Surveillance, and Reconnaissance (ISR) capabilities and denying the understanding of U.S. capability, capacity, readiness, and critical technology and information from adversaries. These investments spur Department innovation and preserve U.S. technology superiority. DOSI analysis and engineering lead the community's ability to sustain and maximize technology advantage as they are transitioned to Service and Agency programs for sustainment, maintenance, and capacity programming. Test and evaluation analyses establish measure and countermeasure effectiveness in current and emerging operational environments.
