IaC Scanning runs in the `test` stage, which is available by default. If you redefine the stages in the `.gitlab-ci.yml` file, the `test` stage is required.
If you use your own runners, make sure the Docker version installed
is **not**`19.03.0`. See [troubleshooting information](../sast/index.md#error-response-from-daemon-error-processing-tar-file-docker-tar-relocation-error) for details.
## Supported languages and frameworks
GitLab IaC scanning supports a variety of IaC configuration files. Our IaC security scanners also feature automatic language detection which works even for mixed-language projects. If any supported configuration files are detected in project source code we automatically run the appropriate IaC analyzers.
| Configuration File Type | Scan tool | Introduced in GitLab Version |
1. IaC scanning can analyze Azure Resource Manager templates in JSON format. If you write templates in the [Bicep](https://learn.microsoft.com/en-us/azure/azure-resource-manager/bicep/overview) language, you must use [the bicep CLI](https://learn.microsoft.com/en-us/azure/azure-resource-manager/bicep/bicep-cli) to convert your Bicep files into JSON before GitLab IaC scanning can analyze them.
1. Terraform modules in a custom registry are not scanned for vulnerabilities. You can follow [this issue](https://gitlab.com/gitlab-org/gitlab/-/issues/357004) for the proposed feature.
### Supported distributions
GitLab scanners are provided with a base alpine image for size and maintainability.
#### FIPS-enabled images
> [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/6479) in GitLab 14.10.
GitLab also offers [FIPS-enabled Red Hat UBI](https://www.redhat.com/en/blog/introducing-red-hat-universal-base-image)
versions of the images. You can therefore replace standard images with FIPS-enabled
images. To configure the images, set the `SAST_IMAGE_SUFFIX` to `-fips` or modify the
The [Security Scanner Integration](../../../development/integrations/secure.md) documentation explains how to integrate other security scanners into GitLab.
[`SAST-IaC.gitlab-ci.yml template`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/ci/templates/Jobs/SAST-IaC.gitlab-ci.yml) provided as part of your GitLab installation. Here is an example of how to include it:
The IaC tool emits a JSON report file in the existing SAST report format. For more information, see the
[schema for this report](https://gitlab.com/gitlab-org/security-products/security-report-schemas/-/blob/master/dist/sast-report-format.json).
The JSON report file can be downloaded from the CI pipelines page, or the
pipelines tab on merge requests by [setting `artifacts: paths`](../../../ci/yaml/index.md#artifactspaths) to `gl-sast-report.json`. For more information see [Downloading artifacts](../../../ci/pipelines/job_artifacts.md).
