NASA depends heavily upon IT to conduct its work. The agency spends at least $1.5 billion annually on IT investments that support its missions, including ground control systems for the International Space Station and space exploration programs. The National Aeronautics and Space Administration Transition Authorization Act of 2017 included a provision for GAO to review the effectiveness of NASA’s approach to overseeing and managing IT, including its ability to ensure that resources are aligned with agency missions and are cost-effective and secure. Accordingly, GAO’s specific objective for this review was to determine the extent to which NASA has established and implemented leading IT management practices in strategic planning, workforce planning, governance, and cybersecurity. To address this objective, GAO compared NASA IT policies, strategic plans, workforce gap assessments, and governance board documentation to federal law and leading practices. GAO also assessed NASA IT security plans, policies, and procedures against leading cybersecurity risk management practices.
