Data Flow Diagramming is a simple diagramming technique used to gain an understanding of how data flows in an application or system. DFD diagrams are especially helpful when conducting threat modeling.
This project extends the free and open source Dia diagramming tool with a new Sheet for doing DFD diagramming:
Installation on Linux is pretty straight-forward:
- Check out the repository with
git clone https://github.com/michenriksen/dia-dfd.git
- Make symbolic links to the diagram shapes with
ln -s /path/to/dia-dfd/shapes/* ~/.dia/shapes/
- Make symbolic link to the diagram sheet with
ln -s /path/to/dia-dfd/sheets/dfd.sheet ~/.dia/sheets/
- Restart Dia if it's already open
You should now have a new Sheet called DFD, ready to use.
