MITRE D3FEND is a knowledgebase of defensive cybersecurity countermeasures, their components and capabilities. It is complementary to the MITRE ATT&CK Framework that describes cybercriminals’ Tactics, Techniques, and Procedures (TTP). The MITRE D3FEND Framework maps relationships between attacker TTP and defensive countermeasures, providing a model of defensive techniques and artifacts to neutralize or mitigate specific offensive cyberattack strategies.ATT&CK stands for Adversarial Tactics, Techniques, and Common Knowledge.
What Is the MITRE D3FEND Framework?
MITRE is a government-backed not-for-profit organization that conducts federally funded cybersecurity research to support defensive IT security across all sectors, including government agencies and defense contractors. MITRE D3FEND™ is a knowledge base—defined as a "knowledge-graph" by MITRE—that serves as a library of defensive cybersecurity countermeasures, technical components, and their associations and capabilities. It is complementary to the MITRE ATT&CK™ framework of cybercriminals’ Tactics, Techniques, and Procedures (TTP).
The MITRE D3FEND Framework maps relationships between ATT&CK's adversary TTP and defensive countermeasures for developing defensive strategy that corresponds directly to known attacker behavior. D3FEND's growing collection of Tactics and Techniques define specific technical elements to monitor to neutralize offensive cyberattacks. The D3FEND framework is relatively new; MITRE released the beta in July 2021.

How to Use the MITRE D3FEND Framework
D3FEND validates a common defensive cybersecurity language and classification hierarchy that can be used between stakeholders when developing a cybersecurity program from the ground up or evaluating an existing cyber program, assessing and comparing the security posture of software or cloud vendors’ products, or informing acquisition and investment.
D3FEND has practical applications for organizations of all sizes, from SMBs to large enterprises. The D3FEND Tactics and Techniques can serve as a checklist for security planners, architects, and decision-makers planning and designing integrated network defenses and software products that will ultimately be the barrier between adversaries and the organization’s digital assets.
Although the ATT&CK framework includes some limited mitigation advisory, D3FEND provides more formalized and organized insight into defensive countermeasures that mitigate and enable a long-term strategy to monitor, detect, and respond to cyberattacks.

What does MITRE D3FEND stand for?
D3FEND stands for Detection, Denial, and Disruption Framework Empowering Network Defense.
Why does MITRE D3FEND reference patents?
IT security patents were the initial focus of D3FEND. Because the patenting system incentivizes inventors and organizations to disclose the details of novel technologies and require legally authoritative assessments, they are a wealth of detailed engineering design information and citations to prior scientific knowledge.
BlackBerry’s suite of Cylance cybersecurity solutions was 100 percent successful in preventing both the Wizard Spider and Sandworm attack emulations very early in MITRE ATT&CK's 2022 evaluation—before any damage occurred.
BlackBerry’s CylancePROTECT® and CylanceOPTICS® solutions provided comprehensive detections on individual attack techniques with high confidence, helping to reduce wasted resources spent chasing false positives.
