```
Python:
```bash
pip install cdktg
```
## How to use
Initialize a project:

### Threat Model written in typescript:
```typescript
// threagile.ts
const project = new Project();
const model = new Model(project, 'Model Stub', {
title: 'Model Stub',
version: '1.0.0',
date: '2020-03-31',
author: new Author({
name: 'John Doe',
}),
businessCriticality: BusinessCriticality.IMPORTANT,
});
const someData = new DataAsset(model, 'Some Data Asset', {
description: 'Some Description',
usage: Usage.BUSINESS,
origin: 'Some Origin',
owner: 'Some Owner',
quantity: Quantity.MANY,
ciaTriad: new CIATriad({
confidentiality: Confidentiality.CONFIDENTIAL,
integrity: Integrity.CRITICAL,
availability: Availability.OPERATIONAL,
}),
});
const someTrustBoundary = new TrustBoundary(model, 'Some Trust Boundary', {
description: 'Some Description',
type: TrustBoundaryType.NETWORK_DEDICATED_HOSTER,
});
const someTechnicalAsset = new TechnicalAsset(model, 'Some Technical Asset', {
trustBoundary: someTrustBoundary,
description: 'Some Description',
type: TechnicalAssetType.PROCESS,
usage: Usage.BUSINESS,
humanUse: false,
size: Size.COMPONENT,
technology: Technology.WEB_SERVICE_REST,
internet: false,
machine: Machine.VIRTUAL,
encryption: Encryption.NONE,
owner: 'Some Owner',
ciaTriad: new CIATriad({
confidentiality: Confidentiality.CONFIDENTIAL,
integrity: Integrity.CRITICAL,
availability: Availability.CRITICAL,
}),
multiTenant: false,
redundant: true,
});
someTechnicalAsset.processes(someData);
const someOtherTechnicalAsset = new TechnicalAsset(model, 'Some Other Technical Asset', {
description: 'Some Description',
type: TechnicalAssetType.PROCESS,
usage: Usage.BUSINESS,
humanUse: false,
size: Size.COMPONENT,
technology: Technology.WEB_SERVICE_REST,
tags: ['some-tag', 'some-other-tag'],
internet: false,
machine: Machine.VIRTUAL,
encryption: Encryption.NONE,
owner: 'Some Owner',
ciaTriad: new CIATriad({
confidentiality: Confidentiality.CONFIDENTIAL,
integrity: Integrity.IMPORTANT,
availability: Availability.IMPORTANT,
}),
multiTenant: false,
redundant: true,
});
someOtherTechnicalAsset.processes(someData);
const someTraffic = someTechnicalAsset.communicatesWith('Some Traffic', someOtherTechnicalAsset, {
description: 'Some Description',
protocol: Protocol.HTTPS,
authentication: Authentication.NONE,
authorization: Authorization.NONE,
vpn: false,
ipFiltered: false,
readonly: false,
usage: Usage.BUSINESS,
});
someTraffic.sends(someData);
const someSharedRuntime = new SharedRuntime(model, "Some Shared Runtime", {
description: "Some Description",
});
someSharedRuntime.runs(someTechnicalAsset, someOtherTechnicalAsset);
project.synth();
```
### High level constructs (cdktg/plus*)
```typescript
import { ApplicationLoadBalancer, Cloud } from "cdktg/plus-aws";
// ...
const alb = new ApplicationLoadBalancer(model, "ALB", {
waf: true,
ciaTriad: new CIATriad({
availability: Availability.CRITICAL,
integrity: Integrity.IMPORTANT,
confidentiality: Confidentiality.CONFIDENTIAL,
}),
});
const cloud = new Cloud(model, "AWS-Cloud");
cloud.addTechnicalAssets(alb);
// ...
```
### cdktg CLI commands:
A running thragile rest api server is required for the CLI. The URL can be passed by parameter `url` or environment variable `CDKTG_THREAGILE_BASE_URL`.
The examples can be used with the [threagile playground](https://run.threagile.io/)
```sh
cdktg [command]
Commands:
cdktg init create a new cdk-threagile project
cdktg synth <filename> synthesize the models
cdktg ping ping the api
cdktg check check the models
cdktg analyze analyze the models
cdktg completion generate completion script
Options:
--help Show help [boolean]
--version Show version number [boolean]
```
