The project, called D3FEND, is available through the non-profit Mitre Corporation as a catalog of defensive cybersecurity techniques and their relationships to offensive/adversary techniques.

The primary goal of the initial D3FEND release is to help standardize the vocabulary used to describe defensive cybersecurity technology functionality.

Mitre described D3FEND as an “early stage experimental research project” with the primary goal of helping to standardize the vocabulary used to describe defensive cybersecurity technology functionality.
