SBOMs

Long term storage of build provenance files / software bills of material (SBOM)

How are SBOM generated?

SLSA

SLSA is not a tool for generating an SBOM, but rather a set of requirements for the SBOM. Currently, the SBOM is generated by this action, which produces SBOM formatted as an In-toto attestation, which is the currently recommended format for an SBOM by SLSA.

There is a workflow called sbom.yml in Spoon that automatically generates the provenance files for Spoon project for every commit to INRIA/spoon:master.

Sonatype-Lift

1. Go to sonatype lift console and click the "dependenices" tab.
2. Click "Export CycloneDX" button to export the SBOM in JSON format.

Renovate

1. Inspired from Renovate's "Detected dependecies".
2. Run the following command and you will get the list of "Detected dependencies" in STDOUT and the log file. bash renovate --token [REDACTED] --dry-run="extract" --autodiscover --autodiscover-filter "<org_name>/<repo_name>" --log-file="renovate.log" One may use Renovate's npm package or docker image to the run the above command.
3. See https://github.com/renovatebot/renovate/discussions/18258#discussion-4463299 for more information.

cdxgen

1. Install cdxgen npm package. sudo npm install -g @appthreat/cdxgen
2. Run. cdxgen -t java -o bom.cdxgen.json

It seems that is uses CycloneDX maven plugin under the hood.

CycloneDX maven plugin

1. Execute the maven-plugin at the root of the maven project. sh $ mvn org.cyclonedx:cyclonedx-maven-plugin:2.7.3:makeAggregateBom
2. The SBOM (bom.json and bom.xml) is written inside the target folder.

jbom

1. Ran Spoon as CLI command and ensured that it would take long to end.
2. Quickly ran jbom on another terminal lise so: sh $ java -jar jbom-1.2.jar -p <process id>

Highlight Automated Code Scan

1. Download the tar ball from the link below.
2. Run the following command from the HLCS directory. sh java -jar HighlightAutomation.jar --workingDir ~/chains/sbom-files/sorald/ --sourceDir ~/spoonlabs/sorald --skipUpload --technologies "Java"

The tools generates a lot of CSV files that can be uploaded to Highlight Platform (proprietary) to view the results.

FOSSA

1. Click 'Start for Free' and then follow the steps.
2. The report can be exported in SPDX format. However, only direct dependecies are included in the report in the free version.

Meterian

1. Download the jar from the link in this page - https://www.meterian.com/downloads/meterian-cli.jar.
2. Run the following command in the root of your project. sh $ java -jar /tmp/meterian-cli.jar
3. It will ask one to authenticate because the final report it generated has limited access.
