To direct the Chief Information Officer of the Department of Defense and the Director of the Defense Information Systems Agency to jointly provide to the Committees on Armed Services of the Senate and House of Representatives a briefing on the plan of the Department of Defense to transition away from the Joint Regional Security Stacks, and for other purposes.

HR 9290 requires the Department of Defense's Chief Information Officer and the Defense Information Systems Agency Director to jointly provide a briefing to the Senate and House Armed Services Committees within 120 days of enactment. The briefing must detail the DoD's plan for transitioning away from the legacy Joint Regional Security Stacks (JRSS) system, focusing on how users will maintain secure access to data and applications under a "zero trust" security model. The bill emphasizes using scalable, certified solutions developed through open vendor processes rather than custom solutions, and ensures the transition meets DoD's 2027 zero trust goals. This is a procedural requirement directing DoD leadership to report on a specific technical transition, affecting only the DoD and congressional committees.
