Tenable step configuration



You can scan your container images and application instances using Tenable and then ingest the results from Harness.

Workflow descriptions​

Orchestration/extraction workflows

This workflow applies to scanner integrations that support orchestratedScan or dataLoad scan modes.

  1. Add a Build or Security stage to your pipeline.

  2. If you're scanning a code repository, set up your codebase.

  3. Add a Custom Scan step.

  4. Review the Important notes for Custom Scan steps for additional requirements and relevant information.

    If you're setting up a scan on a Kubernetes or Docker build infrastructure, you need to add a Docker-in-Docker background step to the stage.

  5. Add the relevant key:value pairs to Settings.

Ingestion workflows

This workflow applies to scanner integrations that support Ingestion mode.

  1. Add a Build or Security stage to your pipeline.

  2. Add a Run step and set it up to save your scan results to a shared folder.

    For more information, go to Run an ingestion scan in an STO Pipeline.

  3. Add a Custom Scan step.

  4. Review the Important notes for Custom Scan steps for additional requirements and relevant information.

  5. Add the relevant key:value pairs to Settings.

Custom Scan step settings for Tenable scans in STO​

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

Scanner settings​

These settings are all required.

Product name​

Key​
product_name
Value​
tenableio

Scan type​

The target type to scan.

Key​
scan_type
Value​

Must be one of the following.

instance

Policy type​

The scan mode to use.

Key​
policy_type
Value​
orchestratedScan
dataLoad
ingestionOnly

Product config name​

Key​
product_config_name
Value​

Use the legacy Nessus scan inside tenableIO:

legacy-web-application-scan

Target and variant​

Every Custom Scan step needs a target and baseline.

Target name​

Key​
target_name
Value​

A user-defined label for the code repository, container, application, or configuration to scan. Specify a unique, descriptive name. This makes it much easier to navigate your scan results in the STO UI.

Target variant​

Key​
target_variant
Value​

A user-defined label for the branch, tag, or other target variant to scan.

Instance​

These settings apply to Custom Scan steps when both of these conditions are true:

  1. The policy_type is orchestratedScan or dataLoad.
  2. The scan_type is instance.

Instance domain​

Key​
instance_domain
Value​

Domain of the application instance to scan. You can include the full path to the app in this field, or split the full path between the instance_domain and the instance_path settings. Example: https://myapp.io/portal/us

Instance path​

Key​
instance_path
Value​

Path to append to the application instance domain, if you're splitting the full path between the instance_domain and the instance_path settings. For example, you might specify the domain as https://myapp.io and the path as /portal/us.

Instance protocol​

Key​
instance_protocol
Value​

One of the following: HTTPS is the default.

HTTPS
HTTP

Instance port​

Key​
instance_port
Value​

The TCP port used by the scanned app.

Instance username​

Key​
instance_username
Value​

The username for authenticating with the scanned app.

Instance password​

Key​
instance_password
Value​

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

Product access​

These settings are available to access your Tenable instance when policy_type is orchestratedScan.

You should create Harness text secrets for your encrypted passwords/tokens and reference them using the format <+secrets.getValue("my-access-token")>.

Product access keys​

product_domain
product_access_id
product_access_token
product_policy_id
product_scanner_id
product_template_uuid

Ingestion file​

This setting applies to Custom Scan steps when the policy_type is ingestionOnly.

Key​
ingestion_file
Value​

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 scan results 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

Fail on Severity​

If the scan finds any vulnerability with the specified severity level or higher, the pipeline fails automatically. NONE means do not fail on severity.

For more information, go to:

Key​
fail_on_severity
Value​
CRITICAL
MEDIUM
LOW
INFO
NONE

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.
