Mend (formerly Whitesource) scanner reference

You can scan container images and repositories using Mend.

Before you begin​

Docker-in-Docker requirements​

note

Docker-in-Docker is not required for ingestion workflows where the scan data has already been generated.

You need to include a Docker-in-Docker background service in your stage if either of these conditions apply:

  • You configured your scanner using a generic Security step rather than a scanner-specific template such as Aqua Trivy, Bandit, Mend, Snyk, etc.
  • You’re scanning a container image using an Orchestration or Extraction workflow.
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.
      3. Image = docker:dind
      4. Under Optional Configuration, select the Privileged checkbox.
Configure the background step

Root access requirements​

You need to run the scan step with root access if either of the following apply:

  • You need to run a Docker-in-Docker background service.

  • You need to add trusted certificates to your scan images at runtime.

note

You can set up your STO scan images and pipelines to run scans as non-root and establish trust for your own proxies using self-signed certificates. For more information, go to Configure STO to Download Images from a Private Registry.

Mend step configuration​

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

note
  • UI configuration support is currently limited to a subset of scanners. Extending UI support to additional scanners is on the Harness engineering roadmap.
  • Each scanner template 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.

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. Using descriptive target names will make it much easier to navigate your scan data in the STO UI.

Variant​

An identifier for a specific variant 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.

You can see the target name, type, and variant in the Test Targets UI:

Target name, type, and branch

Workspace (repository)​

The workspace path on the pod running the Security 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.

Ingestion File​

The results data file to use when running an Ingestion scan. STO steps can ingest scan data in SARIF and Harness Custom JSON format. Generally an Ingestion scan consists of a scan step (to generate the data file) and an ingestion step (to ingest the data file).

Authentication​

Domain​

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​

Lookup Type​

The type of key used to look up the object to scan: password or API key.

Project Name​

The name of the scan project as defined in the scanner. This is the also the target name in the Harness UI (Security Tests > Test Targets).

Include​

The initial scope for the scan. This should match the format required by the scanner.

Exclude​

Exclusions to the initial scope for the scan. This should match the format required by the scanner.

Project Version​

The version of the scan project, as defined in the scanner.

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

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 Unified Agent binary with specific command-line arguments. For example, you can exclude certain files from the scan like this: tool_args = -excludes **/*javadoc.jar.

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)​

You can set up Mend 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.

Target and variant​

The following settings are required for every Security step:

  • target_name A user-defined label for the code repository, container, application, or configuration to scan.
  • variant A user-defined label for the branch, tag, or other target variant to scan.
note

Make sure that you give unique, descriptive names for the target and variant. This makes navigating your scan results in the STO UI much easier.

You can see the target name, type, and variant in the Test Targets UI:

Target name, type, and branch

For more information, go to Targets, baselines, and variants in STO.

Mend scan settings​

  • product_name = whitesource
  • policy_type = ingestionOnly, dataLoad, or orchestratedScan
  • scan_type = container
  • product_domain (optional) — The default is https://saas.whitesourcesoftware.com/api
  • product_access_id
  • product_access_token
  • product_include
  • product_config_name = default
  • product_lookup_type(optional)
  • Accepted value(s) when policy_type is set to dataLoad:
    • byName
    • byTokens
  • Accepted value(s) when policy_type is set to orchestratedScan:
    • appendToProductByToken
    • appendToProductByName
note

You must configure the following settings depending on the product lookup type — i.e., whether you are using the names or tokens to reference the Mend product:

  • product_product_name
  • product_project_name
  • product_project_token
  • product_project_token

Container scan settings​

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

  • 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 file​

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

  • 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. STO steps can ingest scan data in SARIF and Harness Custom JSON format.

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.
