Artifact scans with Wiz



You can easily set up a Wiz step to run automated scans in a Harness pipeline. This step scans the container image you specify using the Wiz CLI. Then it correlates, deduplicates, and ingests the scan results into STO. You can see your scan results in the Security Tests tab of the pipeline execution.

Important notes for running Wiz scans in STO​

The following topics contain useful information for setting up scanner integrations in STO:

Set-up workflows​

Orchestration scans for artifacts

The setup process for Kubernetes and Docker build infrastructures has a few additional steps and requirements.


Prerequisites​


Add a Docker-in-Docker background step​

This is required for orchestrated image scans on Kubernetes or Docker build infrastructures.

Set up a Docker-in-Docker background step

  1. Go to the stage where you want to run the scan.

  2. In Overview, add the shared path /var/run.

  3. In Execution, do the following:

    1. Click Add Step and then choose Background.
    2. Configure the Background step as follows:
      1. Dependency Name = dind
      2. Container Registry = The Docker connector to download the DinD image. If you don't have one defined, go to Docker connector settings reference.
      info

      If your container registry uses a self-signed certificate, the background step will not be able to access the registry by default. Refer to Configure DinD Background step to trust self-signed container registries for instructions.

      1. Image = docker:dind

      2. Under Entry Point, add the following: dockerd

        In most cases, using dockerd is a faster and more secure way to set up the background step. For more information, go to the TLS section in the Docker quick reference.

        If the DinD service doesn't start with dockerd, clear the Entry Point field and then run the pipeline again. This starts the service with the default entry point.

      3. Under Optional Configuration, select the Privileged checkbox.

Configure the background step

Add the Wiz scanner​

Do the following:

  1. Add a CI Build or Security stage to your pipeline.
  2. Add a Wiz step to the stage.

Set up the Wiz scanner​

Required settings​
  1. Scan mode = Orchestration
  2. Target type = Container image
  3. Target and Variant Detection = Auto
  4. Container image:
    1. Type
    2. Domain — Required only if you're using a registry with a non-standard domain, such as a private registry.
    3. Name — for example, jsmith/myimage
    4. Tag — for example, latest
    5. Authentication — Required only if the registry requires authentication:
      1. Registry access Id as a Harness secret
      2. Registry access token as a Harness secret
  5. Authentication:
    1. Wiz access ID as a Harness secret. This is your client-id to authenticate with the Wiz CLI.
    2. Wiz access token as a Harness secret. This is your client-secret to authenticate with the Wiz CLI.
Optional settings​
  • Fail on Severity — Stop the pipeline if the scan detects any issues at a specified severity or higher
  • Log Level — Useful for debugging
Ingestion scans for artifacts
note

Harness STO can ingest both JSON and SARIF data from Wiz, but Harness recommends publishing to JSON because this format includes more detailed information.

Add a shared path for your scan results​

  1. Add a Build or Security stage to your pipeline.
  2. In the stage Overview, add a shared path such as /shared/scan_results.

Copy scan results to the shared path​

There are two primary workflows to do this:

  • Add a Run step that runs a Wiz scan from the command line and then copies the results to the shared path.
  • Copy results from a Wiz scan that ran outside the pipeline.

For more information and examples, go to Ingestion scans.

Set up the Wiz scanner​

Add a Wiz step to the stage and set it up as follows.

Required settings​
  1. Scan mode = Ingestion
  2. Target type = Container Image
  3. Target name — Usually the image name, such as jsmith/myimage
  4. Target variant — Usually the image tag, such as latest. You can also use a runtime input and specify the tag at runtime.
  5. Ingestion file — For example, /shared/scan_results/wiz-scan.json
Optional settings​
  • Fail on Severity — Stop the pipeline if the scan detects any issues at a specified severity or higher
  • Log Level — Useful for debugging

Wiz step settings reference​

The recommended workflow is to add a Wiz step to a Security Tests or CI Build stage and then configure it as described below.

Scan​

Scan Mode​

  • Orchestration Configure the step to run a scan and then ingest, normalize, and deduplicate the results.

Target​

Type​

  • Container Image Scan the layers, libraries, and packages in a container image.

Target and Variant Detection​

When Auto is enabled for container images, the step detects the target and variant using the Container Image Name and Tag defined in the step or runtime input.

Note the following:

  • Auto is not available when the Scan Mode is Ingestion.
  • Auto is the default selection for new pipelines. Manual is the default for old pipelines, but you might find that neither radio button is selected in the UI.

Name​

The identifier for the target such jsmith/myalphaservice. Descriptive target names make it much easier to navigate your scan data in the STO UI.

It is good practice to specify a baseline for every target.

Variant​

The identifier for the specific variant to scan. This is usually the branch name, image tag, or product version. Harness maintains a historical trend for each variant.

Workspace​

The workspace path on the pod running the scan step. The workspace path is /harness by default.

You can override this if you want to scan only a subset of the workspace. For example, suppose the pipeline publishes artifacts to a subfolder /tmp/artifacts and you want to scan these artifacts only. In this case, you can specify the workspace path as /harness/tmp/artifacts.

Additionally, you can specify individual files to scan as well. For instance, if you only want to scan a specific file like /tmp/iac/infra.tf, you can specify the workspace path as /harness/tmp/iac/infra.tf

Container image​

Type​

The registry type where the image is stored:

  • Docker v2 A registry that uses the Docker Registry v2 API such as Docker Hub, Google Container Registry, or Google Artifact Registry. STO will automatically pull and scan the container image or OCI/Docker archive.

  • AWS ECR Set your AWS ECR connector with image details. STO will automatically pull and scan the container image or OCI/Docker archive.

  • Jfrog Artifactory Set your Jfrog Artifactory connector with image details. STO will automatically pull and scan the container image or OCI/Docker archive.

  • Local Image in this Stage Scan a local image built and stored within the context of the current stage (via /var/run/docker.sock registered as a stage level volume mount). For this, you will need to configure Docker-in-Docker as a background step. STO will identify and scan the container image matching the step configuration inside the Docker-in-Docker background within that stage.

  • Local OCI/Docker archive in this Stage Scan an OCI or Docker archive created and stored within the current stage. STO will scan the archive based on the path configured in the workspace field during the step. Ensure that the path to which the archive is saved is a shared volume mount.

Domain​

The URL of the registry that contains the image to scan. Examples include:

  • docker.io
  • app.harness.io/registry
  • us-east1-docker.pkg.dev
  • us.gcr.io

Name​

The image name. For non-local images, you also need to specify the image repository. Example: jsmith/myalphaservice

Tag​

The image tag. Examples: latest, 1.2.3

Access ID​

The username to log in to the image registry.

Access Token​

The access token used to log in to the image registry. This is usually a password or an API key.

You should create a Harness text secret with your encrypted token and reference the secret using the format <+secrets.getValue("container-access-id")>. For more information, go to Add and Reference Text Secrets.

Ingestion File​

The path to your scan results when running an Ingestion scan, for example /shared/scan_results/wiz.latest.json.

  • The data file must be in a supported format for the scanner.

  • The data file must be accessible to the scan step. It's good practice to save your results files to a shared path in your stage. In the visual editor, go to the stage where you're running the scan. Then go to Overview > Shared Paths. You can also add the path to the YAML stage definition like this:

        - stage:
          spec:
            sharedPaths:
              - /shared/scan_results

Authentication​

Access ID​

This is your client-id to authenticate with the Wiz CLI.

Access Token​

This is your client-secret to authenticate with the Wiz CLI.

You should create a Harness text secret with your encrypted token and reference the secret using the format <+secrets.getValue("my-access-token")>. For more information, go to Add and Reference Text Secrets.

Log Level​

The minimum severity of the messages you want to include in your scan logs. You can specify one of the following:

  • DEBUG
  • INFO
  • WARNING
  • ERROR

Additional CLI flags​

Use this field to run the scanner binary with additional flags supported by the external scanner.

caution

Passing CLI flags is an advanced feature. Some flags might not work in the context of STO. You should test your flags and arguments thoroughly before you use them in your production environment.

Fail on Severity​

Every STO scan step has a Fail on Severity setting. If the scan finds any vulnerability with the specified severity level or higher, the pipeline fails automatically. You can specify one of the following:

  • CRITICAL
  • HIGH
  • MEDIUM
  • LOW
  • INFO
  • NONE — Do not fail on severity

The YAML definition looks like this: fail_on_severity : critical # | high | medium | low | info | none

Settings​

You can add more settings to the scan step as needed.

Additional Configuration​

The fields under Additional Configuration vary based on the type of infrastructure. Depending on the infrastructure type selected, some fields may or may not appear in your settings. Below are the details for each field

Advanced settings​

In the Advanced settings, you can use the following options:

View Wiz policy failures​

The Wiz policy failure results appears in the scan results as an Info level issue, categorized as External Policy Issue Type. Additionally, you can apply OPA policies to enforce or manage these failures.

Proxy settings​

This step supports Harness Secure Connect if you're using Harness Cloud infrastructure. During the Secure Connect setup, the HTTPS_PROXY and HTTP_PROXY variables are automatically configured to route traffic through the secure tunnel. If there are specific addresses that you want to bypass the Secure Connect proxy, you can define those in the NO_PROXY variable. This can be configured in the Settings of your step.

If you need to configure a different proxy (not using Secure Connect), you can manually set the HTTPS_PROXY, HTTP_PROXY, and NO_PROXY variables in the Settings of your step.

Definitions of Proxy variables:​

  • HTTPS_PROXY: Specify the proxy server for HTTPS requests, example https://sc.internal.harness.io:30000
  • HTTP_PROXY: Specify the proxy server for HTTP requests, example http://sc.internal.harness.io:30000
  • NO_PROXY: Specify the domains as comma-separated values that should bypass the proxy. This allows you to exclude certain traffic from being routed through the proxy.
