Classified/SIPRNet and JWICS financial processing: unlike weapon-systems and intelligence data architectures, mainstream DoD general-fund financial accounting is predominantly an unclassified (NIPRNet) function, because most appropriated-fund transactions themselves are unclassified even when the underlying program is sensitive. The one clearly documented exception among the systems above is GFEBS-Sensitive Activities (GFEBS-SA), a fully separate, security-hardened instance for classified/sensitive-activity Army funding lines. Special Access Program (SAP-the-acronym-collision, i.e., Special Access Program) financial tracking and intelligence-community (IC) mission funding are handled through separate IC financial-management channels (outside the scope of the conventional-forces systems in this paper) and are not documented in open sources with the same level of system-architecture detail; where sensitive-activity funding must be tracked, DoD's approach has generally been a parallel hardened instance of the same COTS platform (as with GFEBS-SA) rather than a wholly distinct financial system.
