Repository files navigation

This project is in beta and is highly unstable! TMTool was an idea to try and create a risk based threat model (RBTM) approach using the Microsoft threat modeling tool. Tmtool is a set of custom workflows for the inputs & outputs of the Microsoft tool

TMTool

A simple GUI utility that provides additional workflows for Microsoft's Threat Modeling Tool

Installation

$ pip install TMTool

Usage

$ TMTool

The Tkinter GUI containing all the available workflows and scripts:

Build better Threat Knowledge Bases (templates)

  • Search and quickly refine the threat knowledge base
  • View modifications between 2 knowledge bases

Automated Cyber-Risk Scoring

  • Parsing Element properties from a model: For example a flow could have "access vector" as an element prop.
  • Parsing Threat properties from a model: For example a threat have "access complexity" as a threat property.
  • And adding a repeatable way to describe assets and apply those assets to a model’s flows or threats. This step being able to derive CIA, severity, and risk impact of the score.

Dev-Ops Integration

This project experiments with uploading the MS Threat Modeling results to other tools.

  • For Jira, we create a set of issues and set the issue's priority based on the threat ID's risk score.
  • For Confluence, we just upload the generated HTML report to the platform.
