Background for this topic.

Open source is software whose source code is available under a license that permits use, inspection, modification, and redistribution. It may be developed by a community, an organization, or a small group of maintainers; “open” does not guarantee that the code is actively reviewed, supported, or secure.

For security teams, the main concerns are vulnerabilities in dependencies and the software supply chain: a maintainer account, release process, or package can be compromised, while an unmaintained component may retain known flaws. Public code can enable review and faster fixes, but visibility alone is not a control. Maintain an inventory or SBOM of open-source components, pin and verify versions or signatures where possible, monitor vulnerability advisories, and apply updates through a controlled process.
