2022 Year in Review
Modernizing Land-Based U.S. Nuclear Deterrent
The SEI continues its work in software assurance and cybersecurity for the Sentinel program, the new and modernized land-based leg of the U.S. nuclear triad, formerly called the Ground-Based Strategic Deterrent system. In 2022, the technical team advanced its focus on delivering immediate, relevant impact.
The SEI team conducted an architecture evaluation that supports a continuous development cycle and analyzed software assurance to identify risks in not addressing cybersecurity early. Other contributions included groundwork for a software architecture office; formalizing enterprise Agile development processes within the program; improving software measurement, cost analytics, and estimation; workforce development on many software development and acquisition topics; and a nuclear certification technical reference framework.
Activities in 2022 prepared Sentinel to understand and address continuous design to support the DevSecOps framework of continuous development, as well as address planning for software assurance and certification in the coming years.
