Prisma Cloud (formerly Twistlock) scanner reference

You can scan container images using Prisma Cloud.

Before you begin​

To scan a container image, you must have Docker-in-Docker running as a background service in the stage where you're running the scan.

Set up a Docker-in-Docker background step

In the Execution tab, do the following:

  1. Click Add Step and then choose Background.
  2. Configure the Background step as follows:
  3. Dependency Name = dind
  4. Container Registry = The Docker connector to download the DinD image. If you don't have one defined, go to Docker connector settings reference.
  5. Image = docker:dind
  6. Under Optional Configuration, select the Privileged checkbox.
Configure the background step

PrismaCloud step configuration​

The recommended workflow is add a PrismaCloud step to a Security Tests or CI Build stage and then configure it as described below. You can also configure Prisma Cloud scans programmatically by copying, pasting, and editing the YAML definition.

note
  • UI configuration support is currently limited to the following scanners: Aqua Trivy, Bandit, Black Duck, Checkmarx, Grype, Mend, Prisma Cloud, Snyk, SonarQube, and ZAP.
  • Each step palette shows only the options that apply to a specific scan. If you're setting up a repository scan, for example, the UI won't show Container Image settings.
  • Docker-in-Docker is not required for these steps unless you're scanning a container image. If you're scanning a repository using Bandit, for example, you don't need to set up a Background step running DinD.
  • Support is currently limited to Kubernetes and Harness Cloud AMD64 build infrastructures only.
Step Palette

Scan​

Scan Mode​

The orchestration mode to use for the scan. The following list includes the UI and YAML values for the supported options.

  • Orchestrated A fully-orchestrated scan. A Security step in the Harness pipeline orchestrates a scan and then normalizes and compresses the results.
  • Extraction A partially-orchestrated scan. The Security step pulls scan results from an external SaaS service and then normalizes and compresses the data.
  • Ingestion Ingestion scans are not orchestrated. The Security step ingest results from a previous scan (for a scan run in an previous step) and then normallizes and compresses the results.

Scan Configuration​

The predefined configuration to use for the scan. All scan steps have at least one configuration.

Target​

Type​

The target type to scan for vulnerabilities.

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

Name​

The Identifier that you want to assign to the target you’re scanning in the pipeline. Use a unique, descriptive name such as codebaseAlpha or jsmith/myalphaservice.

Variant​

An identifier for a specific target to scan, such as the branch name or image tag. This identifier is used to differentiate or group results for a target. Harness maintains a historical trend for each variant.

Ingestion File​

The results data file to use when running an Ingestion scan. Generally an Ingestion scan consists of a scan step (to generate the data file) and an ingestion step (to ingest the data file).

Container Image​

Type​

The registry type where the image is stored:

Domain​

The URL of the artifact repository that contains the image to scan. Examples:

  • 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​

Username to log in to the container registry.

Access Token​

The access token used to log in to the container registry. In most cases this is 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(project.container-access-id>. For more information, go to Add and Reference Text Secrets.

Authentication​

Domain (extraction)​

The fully-qualified URL to the scanner.

Enforce SSL​

The step and the scanner communicate over SSL by default. Set this to false to disable SSL (not safe).

API Version​

The scanner API version. Some scanners require this.

Type​

The scanner API version. Specify one of the following:

  • Username & Password
  • API Key

Access ID​

Username to log in to the scanner.

Access Token​

The access token to log in to the scanner. In most cases this is 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(project.container-access-id>. For more information, go to Add and Reference Text Secrets.

Scan Tool​

Image Name​

For Extraction scans, the name of the image that you want to extract from Prisma Cloud.

Log Level, CLI flags, and Fail on Severity​

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​

You can use this field to customize the scan with specific command-line arguments supported by that scanner.

Fail on Severity​

Every Security 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 a tool_args setting to run the twistcli images scan binary with specific command-line arguments. For example, you can prevent the scan from publishing results to the Console like this: tool_args = --publish FALSE.

Additional Configuration​

In the Additional Configuration settings, you can use the following options:

Advanced settings​

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

Security step configuration (deprecated)​

Set up a Prisma Cloud scan in a Security step

You can set up Prisma Cloud scans using a Security step: create a CI Build or Security Tests stage, add a Security step, and then add the setting:value pairs as specified below.

Security step dialog box

Here's an example of how to set up a scan in a Security step. scan_type and policy_type are scanner-specific; the other settings are common to scans of container images.

A screenshot of the Harness Platform that highlights the Create Project button in the Feature Flag module.
  • product_name = twistlock
  • scan_type = containerImage
  • policy_type = orchestratedScan, dataLoad, or ingestionOnly
  • When policy_type is set to orchestratedScan or dataLoad:
    • product_image_name
    • product_domain
    • product_access_id
    • product_access_token
  • product_config_name
    • Accepted values(s):
      • default
  • fail_on_severity - See Fail on Severity.
Container image scan settings

The following settings apply to all scanners where the scan_type is containerImage.

  • container_project (required)
  • container_tag (required)
  • container_type
    • accepted value(s): local_image, docker_v2, jfrog_artifactory, aws_ecr
      • for container_type set to local
        • None
      • for container_type set to docker_v2
        • container_access_id: Username
        • container_access_token: Password/Token
      • for container_type set to jfrog_artifactory
        • container_access_id: Username
        • container_access_token: Password/Token
      • for container_type set to aws_ecr
        • container_access_id: Username
        • container_access_token: Password/Token
        • container_region: AWS default region
  • container_domain

Ingestion scan settings

The following settings are required for Security steps where the policy_type is ingestionOnly.

  • target name The Identifier that you want to assign to the target you’re scanning in the pipeline. Use a unique, descriptive name such as codebaseAlpha or jsmith/myalphaservice.

  • variant An identifier for a specific target to scan, such as the branch name or image tag. This identifier is used to differentiate or group results for a target. Harness maintains a historical trend for each variant.

  • ingestion_file The results data file to use when running an Ingestion scan. You should specify the full path to the data file in your workspace, such as /shared/customer_artifacts/my_scan_results.json.

The following steps outline the general workflow for ingesting scan data into your pipeline:

  1. Specify a shared folder for your scan results, such as /shared/customer_artifacts. You can do this in the Overview tab of the Security stage where you're ingesting your data.

  2. Create a Run step that copies your scan results to the shared folder. You can run your scan externally, before you run the build, or set up the Run step to run the scan and then copy the results.

  3. Add a Security step after the Run step and add the target name, variant, and ingestion_file settings as described above.

For a complete workflow description and example, go to Ingest Scan Results into an STO Pipeline.

YAML configuration​

The following YAML pipeline includes example stages for scanning a repository (Bandit step), an image (AquaTrivy step), and an app (ZAP step).

tip

If you want to set up scan steps programmatically using YAML, the best practice is to set up your step in a pipeline using the Visual Editor and then copy, paste, and edit the YAML definition.
