D3FEND 1.0 General Availability

D3FEND 1.0 is here and we are excited to see how you put D3FEND into action!

D3FEND 1.0 Recap & Intro

Last year, we outlined our goals with the 1.0 D3FEND release in our first D3FEND blog post:

• Create a stable, extensible, and integration-friendly version of D3FEND.
• Support sophisticated reasoning applications with a community-developed cybersecurity ontology.
• Expand the model to include access control concepts from a cybersecurity architect’s perspective.
• Align D3FEND with formal upper ontologies to ensure coherence and utility for broader applications.

We are pleased to say we’ve met these goals with 1.0, please review our changelog and release notes for more details.

D3FEND 1.0 is a large release, and represents a paradigm shift in the D3FEND project. Until now, the full power of D3FEND’s ontology has only available to developers who have built their own applications on top of D3FEND. Today, we are announcing a new tool, D3FEND CAD, which enables all users to put the D3FEND ontology into action. D3FEND is now not only a reference but something you can do.

D3FEND CAD is a versatile diagramming tool. With a drag-and-drop interface, users can create semantic diagrams and select from a wide range of taxonomies for both nodes and edges. The tool also supports inferential mappings for various cybersecurity concepts, including defenses, composition, sensors, events, weaknesses, and attacks, when the correct “D3FEND Class” is selected for a node. In short, select the correct class, then right click the nodes to explore the inference and build out your diagram.

What’s next

Stay tuned for our upcoming blog series on D3FEND CAD where we will deep dive into the tool’s features and capabilities.
