LFEL1007 is a Linux Foundation express-learning course about automating practical software-supply-chain security controls: dependency tracking, software bills of materials (SBOMs), attestations and provenance, artifact signatures, and CI/CD checks. It is aimed at developers, open-source maintainers, and IT security professionals who already have some familiarity with Git, command-line tools, continuous integration, and semantic versioning.
What is an SBOM?
A software bill of materials is an inventory of the components in a software product. It helps teams and consumers see which dependencies are present and analyze them for concerns such as licenses and known vulnerabilities. The Linux Foundation presents SPDX as a standard for communicating components, licenses, and known vulnerabilities; CISA guidance and Linux Foundation training materials also identify CycloneDX as a major SBOM format.

An SBOM is useful only to the extent that it is accurate, current, and associated with the artifact it describes. A file generated at one point in a build can become stale, and an SBOM detached from a release does not by itself establish which software was actually shipped. That is why LFEL1007’s subject extends beyond inventory to provenance, signatures, verification, and automation.

What LFEL1007 teaches
Linux Foundation Education describes LFEL1007 as training in evaluating dependency-management solutions, creating attestations, verifying artifact integrity, signing containers, and automating SBOM creation. Its outline moves from software provenance and source control through dependency tracking, tags and signatures, and automated project provenance.
#1 Best Overall
The course’s assessed skills, as reflected in its Credly badge criteria, include Cosign, GUAC, in-toto, SBOMs, SLSA, SLSA-Verifier, and SPDX. The Linux Foundation announcement connects the course’s workflow to in-toto attestations, SLSA verification, Cosign signing, and automated SBOM creation. This makes it a practical introduction to supply-chain security automation, rather than a general software-development course.
Who it is for
The stated audience is software developers, open-source maintainers, and IT security professionals. The expected background includes Git, command-line tools, continuous integration, and semantic versioning. Those prerequisites matter because the material concerns controls applied across source, dependency, build, and release workflows—not just a standalone security product.

How to automate SBOM generation in CI/CD
The central workflow is to create a traceable chain from dependencies and source to a built, signed release, then give a consumer a repeatable way to verify that release before deployment. The course and its announcement support the following sequence; they do not prescribe one universal CI system or a single tool configuration.
- Inventory dependencies. Identify direct and transitive dependencies so the component inventory reflects more than just the packages a project names directly.
- Generate and validate an SBOM. Produce an SBOM in a recognized format, such as SPDX or CycloneDX, and validate it before relying on it for analysis or release documentation.
- Record source and build provenance. Capture information about where the source came from and how the artifact was built. Use attestations, including in-toto concepts, to express and convey claims about that process.
- Apply SLSA provenance and verification practices. Use provenance information and verification practices to assess whether the build process and resulting artifact meet the expected requirements. SLSA-Verifier is among the skills named in the badge criteria.
- Sign release artifacts and container images. Use Cosign/Sigstore to sign the artifacts that consumers need to authenticate, including container images where relevant.
- Automate the controls in CI/CD. Integrate SBOM generation, signing, and policy checks into the project’s delivery pipeline so these actions are part of the release process rather than an informal manual step.
- Provide a consumer verification path. Document how a consumer can check the expected identity, artifact, and relevant trust evidence before deployment.
Automation makes the workflow repeatable; it does not make an inaccurate inventory or weak policy useful. Teams still need to decide which dependencies, provenance claims, signer identities, and policy outcomes are acceptable for their project.
What is the difference between SPDX and CycloneDX?
Both are surfaced by authoritative materials as major SBOM formats, but the available course and guidance descriptions do not establish a field-by-field comparison or declare one universally preferable. Choose based on the tools and requirements that will consume the SBOM, and verify the exact format requirements for the relevant customer or regulatory context.

The practical choice is the format your production and consuming systems can generate, validate, retain, and analyze while meeting the requirements that apply to the release. Format selection alone does not secure a software supply chain.

What are SLSA and in-toto?
In LFEL1007’s workflow, in-toto concepts are associated with attestations: recorded claims about parts of the software process. SLSA is associated with provenance and verification practices. Together, these ideas address how teams record and assess the source and build history behind an artifact; they are distinct from the SBOM’s inventory role and from the cryptographic act of signing a release.

A team must define the provenance claims and verification conditions appropriate to its own release process.

How does Sigstore/Cosign work?
Sigstore’s documentation describes a framework for signing and verifying release files, container images, binaries, SBOMs, and other artifacts. Its verification process checks the certificate identity, the certificate chain to the root of trust, and inclusion evidence in the Rekor transparency log. Cosign is the signing tool explicitly connected to LFEL1007 by the Linux Foundation announcement and badge criteria.
For a consumer, verification is not simply a check that some signature exists. The identity represented by the certificate must be the expected signer, the certificate must chain to the trusted root, the transparency evidence must be valid, and the signed material must be the artifact being considered. A signature provides authenticity and integrity evidence; it does not establish that the software is vulnerability-free or that every provenance claim is adequate.
SBOMs and signatures therefore complement one another. The SBOM provides visibility into declared components; a signature and its verification evidence help establish who signed the artifact and whether the verified artifact matches the signed one. Provenance and policy checks add further context about how it was produced.

LFEL1007 is presented as an express-learning course focused on the workflow and tools above. The available official descriptions provide curriculum, audience, prerequisites, and badge criteria; they do not publish an independent completion, adoption, risk-reduction, or job-outcome statistic. They also do not establish current enrollment status, price, or schedule, so those details should be checked on the Linux Foundation Education course page before enrolling.
For learners who need more than an introduction, the Linux Foundation materials identify LFWS302, “SBOMs in Action,” as a related deeper workshop. Its current availability and terms likewise need confirmation with the provider.
