42Crunch REST API Static Security Testing

ID: 42crunch-security-audit

The REST API Static Security Testing plugin lets you add an automatic static application security testing (SAST) task to your CI/CD pipelines. The task checks your OpenAPI files for their quality and security from a simple Git push to your project repository when the CI/CD pipeline runs.

The plugin is powered by 42Crunch API Contract Security Audit. Security Audit performs a static analysis of the API definition that includes more than 200 checks on best practices and potential vulnerabilities on how the API defines authentication, authorization, transport, and data coming in and going out. For more details on the checks, see API Security Encyclopedia.

As a result of the security testing, your APIs get an audit score, with 100 points meaning the most secure, best defined API. By default, the threshold score for the build task to pass is 75 points for each audited API, but you can change the minimum score in the settings of the pipeline task.

API contracts must follow the OpenAPI Specification (OAS) (formely Swagger). Both OAS v2 and v3, and both JSON and YAML formats are supported.

You can create a free 42Crunch account at https://platform.42crunch.com/register, and then configure the plugin.

Quick start

  1. Install the plugin.
  2. Add the build step to the job.
  3. Add new 42Crunch API Token credential.
  4. Create an API token in 42Crunch platform and copy its value into the credential.
  5. Save the job configuration and run the job.
  6. Click the links in the task output for detailed reports.

For more details, see the full documentation.

Discover APIs

By default, the plugin locates all OpenAPI files in your project and submits them for static security testing. You can include or exclude specific paths from the discovery phase can omit the discovery phase completely by adding a task configuration file 42c-conf.yaml in the root of your repository and specifying rules for the discovery phase. For more details, see the documentation.

Create per-branch reports

During the discovery phase, the plugin automatically creates an API collection in 42Crunch Platform and uploads the audited APIs and reports in there. The default collection name is Jenkins, but you can change this in the job settings.

Fine-tune the build task

You can add a task configuration file 42c-conf.yaml in the root of your repository, and to fine-tune the success/failure criteria. For example, you can choose on whether to accept invalid API contracts, or define a cut-off on a certain level of issue severity.

For more details, see the documentation.
