The authors review options for improving processes for classifying and reclassifying enlisted active-duty, non?prior service airmen for initial skills training in the United States Air Force.

Cyber mission thread analysis (CMTA), which identifies mission-critical systems in a cyber threat environment, requires a disciplined, well-planned process for its execution. This report provides a proposed planning and implementation guide (1) to perform CMTA expeditiously while still giving results good enough to make decisions about mission criticality, and (2) to analyze multiple missions concurrently.

This report presents an examination of how cyber-related risks compare with other risks to defense-industrial supply chains and the implications of the differences in risks for directions in risk assessment and mitigation and for research.

This report helps the Cybersecurity and Infrastructure Security Agency codify the concept of systemically important critical infrastructure by documenting the work surrounding systemic risks and cyber risks in software supply chains.
