Ingest SBOM from Aqua Trivy into SSCA

Harness SSCA offers flexible SBOM management. It can ingest SBOMs generated from Security Testing Orchestration (STO) scanner steps, like the Aqua Trivy STO step, provided the SBOM is in JSON format (SPDX or CycloneDX). This guide details configuring a pipeline to seamlessly ingest SBOMs generated by Trivy.

Alternatively, you can leverage built-in tools in SSCA for SBOM generation or ingest SBOMs from any external tool. Refer to our dedicated guides for these functionalities:

Generate the keys for SBOM Attestation - optional​

For enhanced trust and verification of your SBOM's integrity, the SBOM Orchestration step offers optional signing and attestation generation. This functionality requires a private key, password, and corresponding public key. If you choose to skip signing, you can proceed without generating or storing these keys.

Here's how to set these keys if you choose to enable signing

  • Generate the keys: Begin by generating the keys using Cosign
  • Securely store the keys: Safeguard the generated private key, public key, and password by creating Harness file secrets for each.

Configure the STO scan step to generate SBOM​

Configure an STO scanner step, such as the Aqua Trivy STO step, and make sure you select Generate SBOM and the SBOM Format.

Get the SBOM file path​

The Aqua Trivy STO step creates a JOB_ID output variable that you can use to reference the SBOM file path in the SBOM Orchestration step.

  1. Replace STAGE_ID and STEP_ID in the following Harness expression with the stage ID and step ID for your Aqua Trivy STO step.

    <+pipeline.stages.STAGE_ID.spec.execution.steps.STEP_ID.output.outputVariables.JOB_ID>

  2. Use the expression in your SBOM file path. The exact path depends on where your scanner outputs SBOM files. For example, this filepath references an Aqua Trivy STO step with the ID myaquatrivystep in a stage with the ID mybuildstage:

    /addon/results/<+pipeline.stages.mybuildstage.spec.execution.steps.myaquatrivystep.output.outputVariables.JOB_ID>.sbom
tip

Alternately, you can get the output path and output variable expression from a previous run of the same pipeline. To do this, go to the execution details page, select the stage with the STO scanner step, and then select the STO scanner step. In the step's logs, you can find the output path, and you can get the output variable from the Output tab.

Configure the SBOM Orchestration step​

Add an SBOM Orchestration step and configure to ingest the SBOM.

  • Step Mode: Set the step mode to Ingestion.
  • SBOM File Path: enter the SBOM file path that uses the JOB_ID value, as detailed in Get the SBOM file path.
  • Source: Set the source, which can be DockerHub, ECR, GCR, ACR or Repository. Depending on your selection, a unique set of fields will appear, each specific to the source you've chosen. Address these fields as required, this is similar to configuring the source in SBOM Orchestration step. For more details of what each field entails, please refer to the documentation on SBOM Orchestration. If you are using DockerHub, you can follow along.
  • Image:, Enter the name of your image with tag, such as my-docker-org/repo-name:tag.
  • Private Key: Select the Harness file secret containing the private key to use to sign the attestation.
  • Password: Select the Harness text secret containing the password for the private key.
