MITRE DEFEND Framework
MITRE D3FEND is a knowledge graph of cybersecurity countermeasure techniques that complements the MITRE-ATT&CK framework by providing defensive techniques.
MITRE defend framework overview
DEFEND (Detection, Denial, and Disruption Framework Empowering Network Defense) is a knowledge graph developed by MITRE that catalogs defensive cybersecurity countermeasure techniques. It provides a standardized taxonomy of over 200 defensive techniques organized into seven tactical categories.
While MITRE ATT&CK describes "how adversaries attack," D3FEND describes "how defenders respond." The two frameworks are complementary and bidirectionally mapped, enabling security teams to identify appropriate defensive countermeasures for specific attack techniques.
Key concepts
Defensive Techniques
Over 200 standardized defensive techniques organized hierarchically with parent techniques and sub-techniques. Each technique includes a definition, digital artifacts it operates on, and mappings to ATT&CK offensive techniques.
DEFEND Tactics
Seven high-level tactical categories that organize defensive techniques:
- Model: Understand the system and its behavior
- Harden: Reduce attack surface and vulnerabilities
- Detect: Identify malicious activity
- Isolate: Contain threats and limit damage
- Deceive: Entice, and allow potential attackers access to an observed/ controlled environment
- Evict: Remove threats from the environment
- Restore: Return the system to a better state
Digital Artifacts
Over 800 asset types that defensive techniques operate on or protect, including processes, files, network traffic, user accounts, system calls, and more.
ATT&CK Mappings
Bidirectional mappings between D3FEND defensive techniques and ATT&CK offensive techniques, showing which defensive techniques can counter specific attack methods.
Integration with Threat Intelligence
The ServiceNow Threat Intelligence application integrates DEFEND to provide:
- Automatic ingestion of DEFEND techniques, tactics, and artifacts via API.
- Bidirectional mapping between DEFEND defensive and ATT&CK offensive techniques.
- Coverage analysis showing defensive posture against ATT&CK techniques.
- Task tracking for implementing defensive countermeasures.
