This new tool enables security practitioners to create structured, detailed cybersecurity scenarios grounded in the D3FEND ontology, transforming how organizations model and respond to cyber threats. Developed through collaboration between MITRE, the National Security Agency, and defense departments, including the Cyber Warfare Directorate and the Office of the Under Secretary of Defense for Research and Engineering, D3FEND 1.0 provides organizations with a standardized vocabulary and conceptual framework for cybersecurity operations. As cybersecurity threats continue to evolve in complexity, the D3FEND CAD tool represents an important step toward more rigorous, systematic approaches to security modeling and defense strategy development. This structured approach allows professionals to create what MITRE calls “D3FEND Graphs” – knowledge graphs conforming to the D3FEND Ontology that comprise discrete activities, objects, and conditions with their necessary relationships. “With D3FEND 1.0, you can use the CAD Tool to map out potential threats and defenses, ensuring everyone on your team understands the strategies and terminology being used,” notes cybersecurity expert Julian Boddy. At its core, the system utilizes D3FEND’s comprehensive cybersecurity ontology – a semantically rigorous knowledge graph containing defined types and relations that map the cybersecurity countermeasure domain. MITRE has officially launched its innovative Cyber Attack-Defense (CAD) tool as part of the comprehensive D3FEND 1.0 release. The system also features STIX 2.1 JSON document import capability, mapping STIX Objects to D3FEND ontology classes for enhanced threat intelligence integration.
