### Project T62 — DoD Information Network (DODIN) Systems Engineering and Support

The DoW Information Network (DoWIN) Systems Engineering and Support project identifies key technology areas that are essential to DISA including Machine Learning/Artificial Intelligence (AI), Mobility, Assured Identity, Rapid Transition, and Cyber Defense, among other technologies. It ensures DISA’s technical strategies align with the DoW IT Efficiency Strategy and the latest Department of War Chief Information Office (DoW CIO) Capabilities Planning Guidance (CPG). These strategies establish the foundation for DISA's technology investments and technical development. DISA leverages emerging technology to drive efficiencies and cost savings to the DoW, the Warfighter, and other Federal Agencies. DISA also provides decision-oriented information to the Secretary of War, Joint Staff, Military Services, Combatant Commands, and other mission partners. Key support areas include: Cyber Security and Cloud Computing: Cyber security and cloud computing present critical near-term challenges, especially the ability to securely leverage commercial cloud service offerings. DISA’s partnership with Defense Advanced Research Projects Agency (DARPA) will assess and transition relevant and mature solutions. Solutions included are applications that detect and mitigate cyberattacks, routing capabilities, embedded system defense capabilities, and resilient network capabilities. A major ongoing effort is Quantum Resistant Cryptography (QRC), which uses encryption algorithms to authenticate and secure data-in-transit and at rest that are susceptible to attacks from a computer. QRC is necessary to improve encryption on existing DoW systems, services and applications. DISA is working to measure the impacts of the National Institute of Standards and Technology (NIST) selected QRC algorithms on widely used applications and protocols. Technology Assessments: Through partnerships with industry, academia, and the Federal sectors, DISA produces requisite cyber measures and ensures optimal use of commercial cloud services. DISA will conduct technology assessments, process improvements, and analysis of potential technology to ensure consistency with DoWIN architecture and standards.

> R-2A activities carry the prior, current and budget year only — no five-year plan. Coverage is partial, so count them, never total them.

### Project E65 — Modeling and Simulation and Enterprise Architecture

The Modeling and Simulation activity provides architecture, systems engineering, and E2E analytical functions for DISA and its customers, ensuring integrated capabilities fulfill warfighter mission requirements. Modeling and Simulation activities support the DoW communications planning and investment strategy, to include application performance assessments, contingency planning, network capacity planning and diagnostics, and systems-level modeling and simulation. Efforts provide information awareness for Combatant Commands through application solutions for integrated networks, including DoW’s missions and the Defense Information Systems Network (DISN), by: • Supporting the development and implementation of DoWIN EWSE processes essential to evolving the DoWIN, enabling interoperability, and improving E2E performance for critical DoWIN programs. • Developing standardized systems analyses and integration processes to improve integration across DISA for all DISA-developed communication systems and services to avoid interoperability issues. • Providing underlying modeling, simulation, and analytical support for E2E systems engineering and assessment. The Architecture effort provides interoperability, performance analysis, and systems engineering support for architecture evolution across DISA. DISA works with its customers to ensure integrated capabilities can fulfill warfighter mission requirements and continuously revise these Enterprise Architectures to meet the needs of the department.

## Mission & acquisition strategy

The Defense Information Infrastructure Engineering and Integration effort encompasses two projects, the Modeling and Simulation End-to-End (E2) Architecture and the DoW Information Network (DoWIN) Systems Support. Within the Modeling and Simulation End-to-End Architecture project, there are two major activities: Modeling and Simulation and Enterprise Architecture. Modeling and Simulation: The Modeling and Simulation activity provides systems engineering and E2E analytical functions for DISA and its customers, ensuring integrated capabilities fulfill warfighter mission requirements.

Enterprise Wide Systems Engineering (EWSE) uses contractors to assist/supplement the Government lead/team for technical activities. Subject matter experts in both large and small businesses are sought for the engineering support. Firm fixed price contracts with one option year are typically used in open competition. Modeling and Simulation uses a range of contractors for modeling support to the various projects. Contractors range from small to large business, predominantly using open competition methods and Firm Fixed Price (FFP) tasks and utilizing multi-year (base plus option years) contracts where possible.
