No Longer Maintained
I have released Data Flow Diagram and Attack Tree libraries for draw.io which is much better than Dia. Please see the blog post for more information.
Attack Tree shapes for Dia
From https://www.schneier.com/academic/archives/1999/12/attack_trees.html:
Attack trees provide a formal, methodical way of describing the security of systems, based on varying attacks. Basically, you represent attacks against a system in a tree structure, with the goal as the root node and different ways of achieving that goal as leaf nodes.
This project extends the free and open source Dia diagramming tool with a new Sheet for doing Attack Trees:
Installation on Linux/Mac is pretty straight-forward:
- Check out the repository with
git clone https://github.com/michenriksen/dia-attacktree.git - Make symbolic links to the diagram shapes with
ln -s /path/to/dia-attacktree/shapes/* ~/.dia/shapes/ - Make symbolic link to the diagram sheet with
ln -s /path/to/dia-attacktree/sheets/AttackTree.sheet ~/.dia/sheets/ - Restart Dia if it's already open
You should now have a new Sheet called Attack Tree, ready to use.
