threat-model-manager

Documentation management for threat models

Building it

You can install from npm:

npm i threat-model-manager

Or build from source:

npm i
npm run build

If you build from source you will need to run:

node lib/cli.js generate filename.yaml

Running it

If installed from npm.

Currently there is only one command, generate:

threat-model-manager generate filename.yaml

Input file format

The input file is a YAML file of the following format:

classes:
  node-class-a:
    label: Class A
    threats:
    - type: <threat type>
      threat: text for threat
      notes: some text
      risk: a number
      ticket: a reference to a ticket for resolution/mitigation
components:
  component-a:
    label: Component A
nodes:
  node-name-a:
    label: The name for node a
    component: component-a
    classes:
    - node-class-a
    threats:
    - type: <threat type>
      threat: text for threat
      notes: some text
      risk: a number
      ticket: a reference to a ticket for resolution/mitigation
    flows:
    - to: node-name-b
      threats:
      - type: <threat type>
        threat: text for threat
        notes: some text
        risk: a number
        ticket: a reference to a ticket for resolution/mitigation

The threat types are one of:

• spoofing
• tampering
• repudiation
• information
• denial
• elevation

node names are only used for references between flows and nodes, but the model is checked to ensure there are no dangling references, but orphans are ok.

Output

The output is a graphviz dot file per component, and one overall, plus pngs for each.

Numeric references are generated on the fly, but are not stable if you add or remove nodes or flows.
