“in-toto-run” is a command-line tool designed to generate link metadata while executing a step within a software supply chain. Developed as part of the “in-toto” framework, this tool helps establish trust and accountability by recording the actions taken during each stage of the software development and distribution process. Here are key features and aspects of “in-toto-run”:
- Supply Chain Security: “in-toto-run” addresses concerns related to supply chain security by providing a mechanism to record and verify the actions performed during each step of the software supply chain. It helps ensure the integrity and authenticity of software artifacts by capturing evidence of the actions taken.
- Link Metadata Generation: The tool generates link metadata that captures information about the actions performed during a specific supply chain step. This metadata includes details such as the command executed, input files used, output files generated, cryptographic signatures, and timestamps.
- Integration with Supply Chain Workflow: “in-toto-run” seamlessly integrates into the software supply chain workflow, allowing developers and organizations to incorporate supply chain security measures directly into their build and deployment pipelines. It can be used to record actions during various stages of the development, packaging, and distribution process.
Verification of Actions: The link metadata generated by “in-toto-run” can be independently verified to ensure that the actions performed during the supply chain step were authorized and executed correctly. This verification process helps detect and prevent unauthorized or malicious activities that could compromise software integrity. - Enhanced Trust and Transparency: By recording detailed information about supply chain actions, “in-toto-run” enhances trust and transparency in the software development and distribution process. It provides stakeholders with a clear understanding of the steps taken to produce and deliver software artifacts, improving confidence in their integrity and authenticity.
- Compliance and Auditing: The link metadata generated by “in-toto-run” can be used to demonstrate compliance with regulatory requirements and industry standards related to software supply chain security. It provides auditors and regulators with a reliable record of the actions performed and the controls in place to protect software integrity.
- Command-Line Interface: “in-toto-run” is a command-line tool, designed to be run from the terminal or command prompt. This command-line interface provides flexibility and ease of use, allowing users to integrate the tool into automated build and deployment pipelines.
- Documentation and Support: Users can refer to the official in-toto documentation and website for detailed information on how to use “in-toto-run,” including command syntax, options, examples, and best practices. Additionally, online forums, communities, and tutorials may provide additional support and guidance for users.
in-toto-run Command Examples
1. Tag a git repo and signing the resulting link file:
# in-toto-run -n [tag] --products [.] -k [key_file] --[git tag v1.0]
2. Create a tarball, storing files as materials and the tarball as product:
# in-toto-run -n [package] -m [project] -p [project.tar.gz] -- [tar czf project.tar.gz project]
3. Generate signed attestations for review work:
# in-toto-run -n [review] -k [key_file] -m [document.pdf] -x
4. Scan the image using Trivy and generate link file:
# in-toto-run -n [scan] -k [key_file] -p [report.json] --[/bin/sh -c "trivy -o report.json -f json IMAGE"]
Summary
Overall, “in-toto-run” is a valuable tool for enhancing security and trust in the software supply chain by providing a mechanism to record and verify actions performed during each stage of the process. Its ability to generate link metadata, integrate into supply chain workflows, and support compliance and auditing requirements makes it an essential component of secure software supply chain practices.
