This paper presents the technical and policy issues, architectural considerations, ongoing assessment results, and plans for Distributed Mission Operations Network (DMON) multi-level security (MLS) implementation. In this paper, the Combat Air Force (CAF) Distributed Mission Operations (DMO) Operations and Integration (O&I) team builds on previous Combat Air Force Distributed Mission Operations Multi-Level Security feasibility research and recommendations. Combat Air Force Distributed Mission Operations involves simulations built from components provided by independent vendors for different training communities. The Combat Air Force Distributed Mission Operations MLS problem comes when not all participants have the appropriate clearances for all information. There is a need for aircrews with different capabilities at different security levels, need-to-know, and categories to train together. MLS for simulation is a very challenging problem, not yet solved globally, yet critical to accurate representation of war fighting to distributed audiences at different security levels.

Findings in this paper are based on a Combat Air Force Distributed Mission Operations O&I research and development (R&D) task order focusing on the integration of a MLS Guard into the Combat Air Force Distributed Mission Operations Network. The research involves analyzing and documenting technical architectures for incorporating a MLS Guard into the evolving Combat Air Force Distributed Mission Operations system. The research also will include assessment of the MLS Guard integrated with the Combat Air Force Distributed Mission Operations Portal Kit in a test environment and on the Distributed Mission Operations Network. In addition, the research addresses training feasibility and associated limitations of the guard security rule sets.
