Model-Based Systems Engineering Cybersecurity for Space Systems

As industries in various sectors increasingly adopt model-based systems engineering (MBSE) for system lifecycle design and development, engineers can manage describe of higher complexity than ever before. This is especially true the field space systems; while past missions have developed using document-based planning, it only last several years that NASA other organizations industry begun MBSE. One crucial factor development often overlooked cybersecurity. become more complex cyberphysical nature, cybersecurity requirements difficult to capture, through methods; a need means by which continuously verify validate arises. By expanding upon National Institute Standards Technology (NIST) framework cyber resiliency, this work proposes methodology uses MBSE traceability functionality demonstrate adequate SysML modeling capabilities. Key goals, objectives, strategic principles leading achieving at all levels system’s architectural hierarchy are presented. Recommendations future include addition sector Department Homeland Security Cybersecurity & Infrastructure Agency’s list critical infrastructure improve standardization control cyberinfrastructure.
