Infrastructure as Code (IaC) Scanning

Introduced in GitLab 14.5.

Infrastructure as Code (IaC) Scanning scans your IaC configuration files for known vulnerabilities.

Currently, IaC scanning supports configuration files for Terraform, Ansible, AWS CloudFormation, and Kubernetes.

Requirements

To run IaC scanning jobs, by default, you need GitLab Runner with the docker or kubernetes executor. If you’re using the shared runners on GitLab.com, this is enabled by default.

caution
Our IaC scanning jobs require a Linux container type. Windows containers are not yet supported.
caution
If you use your own runners, make sure the Docker version installed is not 19.03.0. See troubleshooting information 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
Ansible kics 14.5
AWS CloudFormation kics 14.5
Kubernetes kics 14.5
Terraform kics 14.5

Making IaC analyzers available to all GitLab tiers

All open source (OSS) analyzers are availibile with the GitLab Free tier. Future propietary analyzers may be restricted to higher tiers.

Summary of features per tier

Different features are available in different GitLab tiers, as shown in the following table:

Configuration

To configure IaC Scanning for a project you can:

Configure IaC Scanning manually

To enable IaC Scanning you must include the SAST-IaC.latest.gitlab-ci.yml template provided as part of your GitLab installation.

The included template creates IaC scanning jobs in your CI/CD pipeline and scans your project’s configuration files for possible vulnerabilities.

The results are saved as a SAST report artifact that you can download and analyze.

Enable IaC Scanning via an automatic merge request

To enable IaC Scanning in a project, you can create a merge request from the Security Configuration page:

  1. On the top bar, select Menu > Projects and find your project.
  2. On the left sidebar, select Security & Compliance > Configuration.
  3. In the Infrastructure as Code (IaC) Scanning row, select Configure with a merge request.

This automatically creates a merge request with the changes necessary to enable IaC Scanning that you can review and merge to complete the configuration.

Reports JSON format

The IaC tool emits a JSON report file in the existing SAST report format. For more information, see the schema for this report.

The JSON report file can be downloaded from the CI pipelines page, or the pipelines tab on merge requests by setting artifacts: paths to gl-sast-report.json. For more information see Downloading artifacts.
