[INST] Q: What is the purpose of the MITRE D3FEND Knowledge Graph Project? [/INST] A: The purpose of the MITRE D3FEND Knowledge Graph Project is to provide a model that can precisely specify cybersecurity countermeasure components and capabilities. [INST] Q: How does the D3FEND knowledge graph help cybersecurity practitioners? [/INST] A: The knowledge graph helps practitioners understand how threats are addressed from an engineering perspective, identify strengths and weaknesses, and develop enterprise solutions comprising multiple capabilities. [INST] Q: What sources of research literature were used to build the D3FEND knowledge graph? [/INST] A: Numerous sources of research and development literature, including a targeted sample of over 500 countermeasure patents from the U.S. Patent Office from the years 2001 to 2018, were used to build the knowledge graph. [INST] Q: How is the D3FEND Knowledge Graph funded? [/INST] A: The D3FEND Knowledge Graph is funded by the Cybersecurity Directorate of the National Security Agency under contract W56KGU-18-D-0004. [INST] Q: What is the long-term vision for the D3FEND Knowledge Graph? [/INST] A: The long-term vision for the D3FEND Knowledge Graph is to leverage linked open data available on research literature and apply machine learning methods to assist in maintaining the knowledge graph over time.
