OWASP Threat Dragon

Threat Dragon is a free, open-source, cross-platform threat modeling application including system diagramming and a rule engine to auto-generate threats/mitigations. It is an OWASP Incubator Project. The focus of the project is on great UX, a powerful rule engine and integration with other development lifecycle tools.

There is a good overview of threat modeling and risk assessment from OWASP, and this expands on what Threat Dragon will achieve:

• designing the data flow diagram
• automatic determining and ranking threats
• suggested mitigations
• entry of mitigations and counter measures

The application comes in two variants:

1. A web application: For the web application, models files are stored in GitHub (other storage will become available). We are currently maintaining a working protoype in synch with the master code branch.

2. A desktop application: This is based on Electron. There are builds available for Windows and OSX (Linux will follow at some point). For this variant models are stored on the local filesystem.

End user help is available for both variants.

This repository contains the files for the desktop variant.

Status

The desktop variant is a work-in-progress, but it basically works. To install and run it locally:

git clone https://github.com/mike-goodwin/owasp-threat-dragon-desktop

npm install

Then to run it on a Mac/Linux:

npm start

Or on Windows:

.\node_modules\.bin\electron .

Installers for OSX and Windows can be downloaded from the releases folder. A Linux version will follow soon.

Screenshots

Here are a few screenshots of the app to give you a feel for what it looks like. First, the welcome screen

The diagramming screen:

And the threat editing screen

Limitations

The unit tests for the project are currently broken :(

Due to a lack of code signing, you may get a warning when installing on Windows and AutoUpdate on OSX does not work.

Contributing

PRs, feature requests, bug reports and feedback of any kind are very welcome. We are trying to keep the test coverage relatively high, so please try to include tests in any PRs and make PRs on the development branch.
