When it comes to agile software development, ensuring security isn’t just about your in-house code anymore—it’s about the entire software supply chain. Ever found yourself wondering about the myriad dependencies in your project and why they’re there?
That’s where the Software Bill of Materials (SBOM) comes into play – think of it as a comprehensive guide that reveals the contents and origins of your application’s code. There are multiple tools for crafting SBOMs, but in this blog, we will delve into the specifics of leveraging SBOM with GitLab Actions.
What is GitLab?
GitLab serves as a web-centric platform catering to version control, continuous integration, and collaborative efforts in software development. Functioning as an extensive DevOps lifecycle tool, GitLab empowers teams to oversee and monitor source code alterations, thereby building developers’ cooperation. It encompasses functionalities such as issue tracking, code review, and an integrated CI/CD system, streamlining the intricacies of development workflows.
With a consolidated interface, GitLab supports both the hosting of Git repositories and project management, providing a unified solution for code repositories, issue tracking, and CI/CD pipelines. Notably, it has strong security features, encompassing container scanning and vulnerability management, thereby elevating the overall development process.
GitLab’s open-source character and adaptability position it favorably as a go-to option for organizations seeking to optimize their software development lifecycle.
Benefits of Utilizing SBOM with GitLab Actions
Integrating Software Bill of Materials (SBOM) with GitLab Actions offers several strategic advantages:
Transparency and Values Alignment:
Generating accurate SBOMs aligns with GitLab’s core value of transparency. SBOMs provide thorough insights into software components, including origin and vulnerability details, promoting transparency and adherence to open core principles.
Risk Mitigation and Informed Decision-Making:
Lack of visibility into software dependencies is a significant risk. SBOMs empower GitLab to make well-informed decisions rapidly, drawing insights from diverse sources. This robust risk management approach enhances decision-making in the software development lifecycle.
Competitive Differentiation:
Being a frontrunner in the DevSecOps domain, GitLab’s emphasis on SBOMs sets a higher benchmark. Excelling not only in product features but also in customer confidence regarding SBOMs gives GitLab a competitive advantage, positioning it as an industry pacesetter.
Efficiency and Standardization:
Embracing standardized formats such as CycloneDX and VEX simplifies communication. This ensures a clear understanding of software dependencies and vulnerabilities, eradicating ambiguities and boosting operational efficiency for GitLab and its user base.
Regulatory Compliance Readiness:
Anticipating evolving regulatory landscapes, GitLab’s integration with SBOMs positions it ahead of compliance requirements. With references to U.S. federal orders, cybersecurity strategies, and ongoing legislative developments, GitLab is prepared for dynamic regulatory changes in the software supply chain.
Which type of SBOM is used for GitLab?
As of version %16.4, GitLab utilizes the CycloneDX format for SBOM within its product features. Within the GitLab ecosystem, several features have been seamlessly incorporated to enhance SBOM-related functionalities:
CycloneDX-Formatted SBOMs: GitLab now possesses the capability to generate SBOMs in the CycloneDX format. This extends to the generation of CycloneDX-formatted SBOMs following both Dependency and Container scans within GitLab.
Dependency List: A pivotal addition is the Dependency List feature embedded in GitLab, consolidating vulnerability and license data from the existing GitLab databases. This empowers users to gain comprehensive insights into dependencies within their projects.
API for Pipeline-Specific CycloneDX SBOM Exports: With version %16.4, GitLab has introduced an Application Programming Interface (API) facilitating the export of CycloneDX SBOMs tailored to specific pipelines. This API introduces a more nuanced and customizable approach to SBOM generation.
Group-Level Dependency Lists: GitLab has expanded dependency management by enabling the creation of group-level dependency lists. This extends the oversight of dependencies to a broader organizational level.
Despite GitLab’s proficiency in generating CycloneDX SBOMs for most projects, it’s essential to note that, as of version %16.4, the company primarily leverages Dependency Lists to access vulnerability information for key projects.
Notably, GitLab does not actively ingest these CycloneDX SBOMs, amalgamate them, produce VEX BOMs (Vulnerability and EXposure), nor readily provide them to customers. This snapshot represents GitLab’s current status as of version %16.4.
Create SBOM Maturity Model with GitLab
To create an SBOM Maturity Model with GitLab, ensuring the comprehensive generation and management of Software Bill of Materials (SBOMs), follow these steps based on the information provided:
1. Automatic SBOM Generation in CycloneDX Format:
- Ensure that GitLab repositories can automatically generate complete and accurate SBOMs in the accepted format, such as CycloneDX.
- Confirm that the generated SBOMs include all of NTIA’s recommended minimum data elements: Supplier Name, Component Name, Version of the Component, Other Unique Identifiers, Dependency Relationship, Author of SBOM Data, and Timestamp.
- Enable fields like Dependency Relationship and Author, if not already available, by submitting a feature request for missing fields.
2. Source SBOM from Development Environment:
- Leverage GitLab’s existing Dependency List feature, which allows creating a “Source SBOM” directly from the development environment, source files, and included dependencies used to build a product artifact.
- Explore the possibility of exporting the Dependency List into CycloneDX format to meet the accepted standard.
3. Analyzed SBOM for Artifacts:
- Utilize GitLab’s existing capability to generate “Analyzed SBOMs” through the analysis of artifacts (e.g., executables, packages, containers, and virtual machine images) after their build.
- Leverage the CycloneDX SBOMs produced in CI pipelines for both Dependency Scanning and Container Scanning.
4. Digital Signing of SBOMs:
As mentioned in GitLab’s planned features under Software Supply Chain Security, ensure future support for digitally signing SBOMs at build or release time. This would contribute to the integrity and authenticity of SBOMs.
Documentation and Communication:
- Document the processes and features within GitLab that support each aspect of the SBOM Maturity Model.
- Communicate the availability and usage of these features to GitLab users and administrators.
By following these steps, you can establish a robust SBOM Maturity Model within GitLab, aligning with industry standards and ensuring transparency and security in the software supply chain. Keep an eye on GitLab’s updates and feature releases to stay aligned with the evolving landscape of SBOM requirements.
