Model-based systems engineering (MBSE) is a formalized methodology that is used to support the requirements, design, analysis, verification, and validation associated with the development of complex systems. In contrast to document-centric engineering, MBSE puts models at the center of system design. The increased adoption of digital-modeling environments during the past few years has led to increased adoption of MBSE. In January 2020, NASA noted this trend by reporting that MBSE, "has been increasingly embraced by...

The SEI Source Code Analysis Integrated Framework Environment (SCAIFE) is a modular architecture designed to enable a wide variety of tools, systems, and users to use artificial intelligence (AI) classifiers for static-analysis meta-alerts at relatively low cost and effort. SCAIFE uses automation to reduce the significant manual effort required to adjudicate meta-alerts that are produced by static-analysis tools. The architecture also enables low-effort integration for tools to incorporate mathematical formulas for meta-alert prioritization, data aggregation...

To ensure that risk management is effective, organizations need adaptable, agile frameworks that provide executives with a real-time view of cyber risks, and the related tools and processes they can use to address appropriate risks. Organizations should use enterprise risk management (ERM) principles, tools, and processes to understand and prioritize complex risks that compete for organizational resources. The SEI developed OCTAVE FORTE, a process model that helps organizations evaluate their security risks and use ERM...
