Today, we’re saying the launch of the v0.1 model of Graph for Understanding Artifact Composition (GUAC). Introduced at Kubecon 2022 in October, GUAC targets a essential want within the software program business to grasp the software program provide chain. In collaboration with Kusari, Purdue University, Citi, and group members, we’ve got integrated suggestions from our early testers to enhance GUAC and make it extra helpful for safety professionals. This improved model is now out there as an API so that you can begin creating on high of, and integrating into, your techniques.
High-profile incidents corresponding to Solarwinds, and the latest 3CX provide chain double-exposure, are proof that provide chain assaults are getting extra subtle. As highlighted by the U.S. Executive Order on Cybersecurity, there’s a essential want for safety professionals, CISOs, and safety engineers to have the ability to extra deeply hyperlink info from completely different provide chain ecosystems to maintain up with attackers and forestall publicity. Without linking completely different sources of data, it’s not possible to have a transparent understanding of the potential dangers posed by the software program elements in a corporation.
GUAC aggregates software program safety metadata and maps it to a normal vocabulary of ideas related to the software program provide chain. This information will be accessed by way of a GraphQL interface, permitting growth of a wealthy ecosystem of integrations, command-line instruments, visualizations, and coverage engines.
We hope that GUAC will assist the broader software program growth group higher consider the availability chain safety posture of their organizations and initiatives. Feedback from early adopters has been overwhelmingly optimistic:
“At Yahoo, we have found immense value and significant efficiency by utilizing the open source project GUAC. GUAC has allowed us to streamline our processes and increase efficiency in a way that was not possible before,” mentioned Hemil Kadakia, Sr. Mgr. Software Dev Engineering, Paranoids, Yahoo.
Dynamic aggregation
GUAC is not only a static database—it’s the first software that’s constantly evolving the database pertaining to the software program that a corporation develops or makes use of. Supply chains change each day, and by aggregating your Software Bill of Materials (SBOMs) and Supply-chain Levels for Software Artifacts (SLSA) attestations with risk intelligence sources (e.g., OSV vulnerability feeds) and OSS insights (e.g., deps.dev), GUAC is continually incorporating the most recent risk info and deeper analytics to assist paint a extra full image of your danger profile. And by merging exterior information with inside personal metadata, GUAC brings the identical degree of reasoning to an organization’s first-party software program portfolio.
Seamless integration of incomplete metadata
Because of the complexity of the fashionable software program stack—typically spanning languages and toolchains—we found throughout GUAC growth that it’s troublesome to provide high-quality SBOMs which can be correct, full, and meet specs and intents.
Following the U.S. Executive Order on Cybersecurity, there at the moment are a lot of SBOM paperwork being generated throughout launch and construct workflows to elucidate to shoppers what’s of their software program. Given the issue in producing correct SBOMs, shoppers typically face a state of affairs the place they’ve incomplete, inaccurate, or conflicting SBOMs. In these conditions, GUAC can fill within the gaps within the varied provide chain metadata: GUAC can hyperlink the paperwork after which use heuristics to enhance the standard of information and guess on the appropriate intent. Additionally, the GUAC group is now working intently with SPDX to advance SBOM tooling and enhance the standard of metadata.
GUAC’s course of for incorporating and enriching metadata for organizational perception
Consistent interfaces
Alongside the increase in SBOM manufacturing, there’s been a fast growth of latest requirements, doc sorts, and codecs, making it arduous to carry out constant queries. The a number of codecs for software program provide chain metadata typically confer with related ideas, however with completely different phrases. To combine these, GUAC defines a standard vocabulary for speaking in regards to the software program provide chain—for instance, artifacts, packages, repositories, and the relationships between them.
This vocabulary is then uncovered as a GraphQL API, empowering customers to construct highly effective integrations on high of GUAC’s data graph. For instance, customers are capable of question seamlessly with the identical instructions throughout completely different SBOM codecs like SPDX and CycloneDX.
According to Ed Warnicke, Distinguished Engineer at Cisco Systems, “Supply chain safety is more and more about making sense of many alternative sorts of metadata from many alternative sources. GUAC knits all of that info collectively into one thing comprehensible and actionable.”
Based on these options, we envision potential integrations that customers can construct on high of GUAC in an effort to:
-
Create insurance policies based mostly on belief
-
Quickly react to safety compromises
-
Determine an improve plan in response to a safety incident
-
Create visualizers for information explorations, CLI instruments for giant scale evaluation and incident response, CI checks, IDE plugins to shift coverage left, and extra
Developers can even construct information supply integrations below GUAC to develop its protection. The total GUAC structure is plug-and-play, so you possibly can write information integrations to get:
-
Supply chain metadata from new sources like your most well-liked safety distributors
-
Parsers to translate this metadata into the GUAC ontology
-
Database backends to retailer the GUAC information in both widespread databases or in organization-defined personal information shops
Dejan Bosanac, an engineer at Red Hat and an energetic contributor to the GUAC challenge, additional described GUAC’s ingestion talents, “With mechanisms to ingest and certify data from various sources and GraphQL API to later query those data, we see it as a good foundation for our current and future SSCS efforts. Being a true open source initiative with a welcoming community is just a plus.”
Google is dedicated to creating GUAC the perfect metadata synthesis and aggregation instrument for safety professionals. GUAC contributors are excited to satisfy at our month-to-month group calls and look ahead to seeing demos of latest purposes constructed with GUAC.
“At Kusari, we are proud to have joined forces with Google’s Open Source Security Team and the community to create and build GUAC,” says Tim Miller, CEO of Kusari. “With GUAC, we believe in the critical role it plays in safeguarding the software supply chain and we are dedicated to ensuring its success in the ecosystem.”
Google is getting ready SBOMs for consumption by the US Federal Government following EO 14028, and we’re internally ingesting our SBOM catalog into GUAC to collect early insights. We encourage you to do the identical with the GUAC launch and submit your suggestions. If the API just isn’t versatile sufficient, please tell us how we are able to prolong it. You can even submit options and suggestions on GUAC growth or use instances, both by emailing guac-maintainers@googlegroups.com or submitting a difficulty on our GitHub repository.
We hope you will be part of us on this journey with GUAC!
