The text discusses the importance of visibility in a software supply chain to ensure the safety and security of developed software. It highlights the need for audit logs, Software Bill of Materials (SBOMs), automation, and package management to bring transparency into the build process. The article then dives deeper into specific strategies such as automated build steps, versioning software, pinning dependencies, automated dependency updates, scorecards, signing artifacts, generating SBOMs, and provenance of built artifacts. These measures can help answer questions like what is installed on a system, who wrote the code, and how to trace builds from source to deployment. Additionally, observability tools can provide insights into unusual behavior, identify vulnerabilities, and detect potential security incidents, ultimately securing the software supply chain.
