Aqua Security scanner reference for STO



You can scan your container images and ingest scan results from Aqua Security Enterprise.

The Aqua Security step can also ingest assurance policy violations. These violations appear as INFO-level issues in Security Tests.

Important notes for running Aqua Security scans in STO

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

Aqua Custom Scan step settings for STO scans

The recommended workflow is to add an Aqua Security step to a Security or 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.

Scan Configuration

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

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 as codebaseAlpha or 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.

Container image

Type

The registry type where the image is stored:

Domain (extraction)

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

Region

The region where the image to scan is located, as defined by the cloud provider such as AWS.

Authentication

Access Domain

The fully-qualified URL to the scanner.

Access Token

The access token to log in to the scanner. 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("my-access-token")>. For more information, go to Add and Reference Text Secrets.

Access Region

The AWS region of the image to scan.

Ingestion

Ingestion File

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

  • 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

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 additional CLI flags is an advanced feature. Harness recommends the following best practices:

  • Test your flags and arguments thoroughly before you use them in your Harness pipelines. Some flags might not work in the context of STO.

  • Don't add flags that are already used in the default configuration of the scan step.

    To check the default configuration, go to a pipeline execution where the scan step ran with no additional flags. Check the log output for the scan step. You should see a line like this:

    Command [ scancmd -f json -o /tmp/output.json ]

    In this case, don't add -f or -o to Additional CLI flags.

Fail on Severity

Every Custom 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

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:
