No Longer Maintained

I have released Data Flow Diagram and Attack Tree libraries for <a href="https://www.draw.io/">draw.io</a> which is much better than Dia. Please see <a href="http://michenriksen.com/blog/drawio-for-threat-modeling/">the blog post</a> for more information.

# Data Flow Diagramming shapes for [Dia](https://wiki.gnome.org/Apps/Dia)

[Data Flow Diagramming](https://en.wikipedia.org/wiki/Data_flow_diagram) 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](https://www.owasp.org/index.php/Application_Threat_Modeling).

This project extends the free and open source [Dia](https://wiki.gnome.org/Apps/Dia)
diagramming tool with a new Sheet for doing DFD diagramming:

![Example of how the shapes look in Dia](https://raw.githubusercontent.com/michenriksen/dia-dfd/master/example.png)

## Installation

Installation on Linux is pretty straight-forward:

1. Check out the repository with `git clone https://github.com/michenriksen/dia-dfd.git`
 2. Make symbolic links to the diagram shapes with `ln -s /path/to/dia-dfd/shapes/* ~/.dia/shapes/`
 3. Make symbolic link to the diagram sheet with `ln -s /path/to/dia-dfd/sheets/dfd.sheet ~/.dia/sheets/`
 4. Restart Dia if it's already open

You should now have a new Sheet called DFD, ready to use.

**Happy diagramming!**
