GUAC Blog

Licenses are the foundation of open source software. They grant the permissions that we rely on to use, inspect, and modify code. But software licenses can also place obligations on you. This is why it’s important to know what licenses exist in your dependency graph.

GUAC records the license information provided in your software bills of materials (SBOMs) into a CertifyLegal node. That information isn’t always complete, though, so GUAC augments with information from deps.dev and ClearlyDefined. This gives you a lot of information to work with. For example: you can find packages where ClearlyDefined’s scan yields a different set of licenses than what the project reports.

To start, you can use a GraphQL query to return all packages and source locations with a CertifyLegal node:

{
  CertifyLegal(certifyLegalSpec: {}) {
    discoveredLicense
    declaredLicense
    subject {
      ... on Package {
        namespaces {
          namespace names{
            name
          }
        }
      }
      ... on Source {
        namespaces {
          namespace names{
            name
          }
        }
      }
    }
  }
}

But what do you do with the output? I wrote a short Python script that gets data from your GUAC server with the query above. It then looks for packages and sources where the declared and discovered license strings don’t match. Because this can be a long list (the demo data returns hundreds of results), you can also write the output to a CSV file.

This script is a simple demo. It does not account for trivial differences. It also doesn’t try to make sense of the practical impact of license combinations. You can see, though, how you can quickly write your own script to find out the answer to your own questions.

The power of GUAC is the way it enriches your SBOMs. It collects additional information to make searches like this possible. If you do something interesting with this, we’d love to hear about it. Let us know in Slack or at an upcoming community meeting. The community page has all the details.

Join the GUAC community Thursday at 1PM Eastern (1700 UTC) for the October Community Meeting.

Topics include:

• Maintainer decisions about supported GUAC backends
• A look at the stats of our demo pages and how we might change them

GUAC v0.10.0 is now available. Version 0.10.0 contains several fixes, one of which makes a minor change to GraphQL queries. Previously, a certifier query could hit PostreSQL’s limit of 65535 parameters. Now the queryPackagesListForScan query is split into two: a listing of non-GUAC-type package IDs that require rescanning and a second query that gives the certifier a list of packages to scan.

This release also contains a fix from Robbie Cronin for query failures in the key-value backend when a CertifyLegal node is empty.

See the v0.10.0 release page for full details.

GUAC v0.9.0 is now available. This release includes a compatibility-breaking change in the CLI introduced in v0.8.9.

Version 0.9.0 improves performance of certifiers by not re-querying recently-updated packages. The new last-scan option takes a numeric value in hours and will exclude packages that were updated within that time frame. The last-scan defaults to 4. Using a value of 0 will force the certifier to re-query all packages.

Version 0.8.9 introduced a compatibility-breaking change to the vulnerability query command line. Commands now take the form guacone query vuln <type> <input> where type is one of “artifact”, “purl”, or “uri” and input is a corresponding string. This enable support for searching for vulnerabilities via artifact.

In addition, the new releases include several smaller bug fixes. See the v0.8.9 and v0.9.0 release pages for full details.

It’s almost October, which means Hacktoberfest is just around the corner. The best way to ensure your supply chain is secure and well-maintained is to contribute upstream. Hacktoberfest can be a forcing function to start your upstream contributions. But how do you figure out which Hacktoberfest participants in your dependency graph? Use GUAC!

GUAC uses information from your software bills of materials (SBOMs) and the deps.dev service to build a graph of your software dependencies. Included in this information is the HasSourceAt node, which gives the location of the package’s source code. This is often a GitHub or GitLab repository. Conveniently, both of these sites are official sites for Hacktoberfest. Projects hosted on either of those platforms can opt in by adding the “hacktoberfest” topic. Both GitHub and GitLab offer an API for searching for projects. So all of the information you need exists, you just have to tie it together.

The GraphQL query to return all packages with a HasSourceAt node is straightforward:

{
  HasSourceAt(hasSourceAtSpec: {}) { 
      source{
        type namespaces{
          namespace names{
            name } 
        }
      }
  }
}

But what do you do with the output? I wrote a short Python script that gets data from your GUAC server with the query above. It then pulls a list of Hacktoberfest projects from GitHub and GitLab. Finally, it prints any of your dependencies that appear in the Hacktoberfest list. In just a minute or two, you can have a list of projects to go work on.

The output for the demo data includes seven projects as of this writing:

Here are the Hacktoberfest projects in your GUAC data:
github.com/grpc/grpc-go
github.com/schollz/progressbar
github.com/gopherjs/gopherjs
github.com/google/go-github
github.com/containerd/containerd
github.com/grpc/grpc-go
github.com/containerd/containerd

Of course, you’re not limited to what’s in this example script. You could modify it to rank based on OpenSSF Scorecard scores, the number of times a dependency appears in the graph, or other factors you can think of. The power of GUAC is the way it enriches your SBOMs. It collects additional information to make searches like this possible. If you do something interesting with this, we’d love to hear about it. Let us know in Slack or at an upcoming community meeting. The community page has all the details. If you want to contribute to GUAC as part of Hacktoberfest, we’re participating.

This year marks the 11th edition of Hacktoberfest, the annual event to celebrate and promote contribution to open source projects. The GUAC project is participating with two of our repos: the GUAC Docs and GUAC Visualizer. You can find specifics about what we’re looking for below, but all contributions are welcome.

To participate, register on the Hacktoberfest website. If you have four pull requests merged to any participating repository in October, you get a digital badge from Hacktoberfest. If you have any pull request merged to a GUAC repo, Kusari will send you some GUAC swag!

See the contributing page on the website and the README files in each repo for information on how to contribute to GUAC. If you have any questions, join us on Slack or in the GUAC Time office hours.

GUAC Docs

The guac-docs repo contains the source for the documentation and demos at docs.guac.sh. We have good demos that show the basics of how GUAC works, but we need more reference material and explanations of how GUAC works. The repo has a good set of issues with suggestions, but we’d welcome any other improvements you can think of. Even if you can’t contribute the documentation, opening an issue in this repo for anything you find confusing or missing would be a big help, too.

GUAC Visualizer

The experimental GUAC Visualizer is a way to visually display and explore the supply chain. This repo isn’t a core focus of the project, but it’s an important part of demos and the onboarding experience. We’d love to have your help improving this tool. GUAC Visualizer is a Next.js application. There are some open issues to work on, or you can bring your own ideas.

GUAC v0.8.7 is now available. This release includes a fix for a bug that could lead to a panic when querying for vulnerabilities using an SBOM URI. It also adds logging for the beginning and end of certifier runs. The GitHub release page includes a full list of changes.

Version 0.4.5 of the experimental GUAC Visualizer is now available. The GUAC Visualizer is an experimental utility that can be used to interact with GUAC services. It acts as a way to visualize the software supply chain graph and explore the supply chain.

The main change in version 0.4.5 is the addition of a new window that displays known information about a package. This package information box, contributed by Shafee Ahmed, gives you quick access to information about a package’s vulnerabilities, SBOM source, and SLSA attestations.

This release also includes an update of the GraphQL schema to work with recent GUAC releases, plus a few other minor fixes and dependency updates. See the GitHub release page for a full list of changes. It includes first-time contributions to the GUAC Visualizer from:

• Kris Borchers
• Ben Cotton
• @haosanzi
• Parth Patel

If you paid close attention to the GUAC Visualizer, you might have noticed that the previous release was version 0.3.1. What happened between then? Several changes in the build pipeline were necessary due to changes in the tools we use. Versions 0.4.0 through 0.4.4 were part of the diagnosis and remediation of build pipeline issues. As part of this work, we’ve now created a CI build workflow that runs a build on all pull requests. This is a common practice and will help us catch some issues earlier. We’d love your help with GUAC Visualizer. See the “help wanted” or “good first issue” tags in GitHub for suggestions.

GUAC v0.8.6 is now available. It fixes one bug from the just-released version 0.8.5, which includes a few improvements. The command line vulnerability query now searches for hasSBOM nodes on artifacts. In addition, the CycloneDX parser now captures version for image artifacts. Finally, the Docker compose files provided in the release now include the ClearlyDefined certifier that was added in GUAC 0.8.0.

This release also contains several bug fixes. The GitHub release page has a complete list of changes in this release. Want to contribute to GUAC? You can join our community.

Join the GUAC community Thursday at 1PM Eastern (1700 UTC) for the September Community Meeting.

Topics include:

• Demo of some example guac scripts: guactober & license_check
• New guac-visualizer release
• Hacktoberfest participation: guac-docs and guac-visualizer

If you have your own topics to discuss or cool GUAC insights, join us and share with the community!

If you can’t make it, the recording will be posted to our YouTube channel.

Join members of the GUAC Community for another episode of Cloud Native Live on Tuesday, September 24. In a previous episode of Cloud Native Live, we showed how GUAC can be used to locate and remediate vulnerabilities. But fully understanding the software supply chain is more than just finding vulnerabilities.

In this session, you’ll learn about other insights that GUAC can help you discover from licenses to dependencies participating in Hacktoberfest. Plus, you’ll see how GUAC can be used as an Kubernetes admission controller.

Join us for another fun session to taco’bout GUAC! RSVP on the event page or catch the recording on the CNCF YouTube channel.

If you’ll be at Open Source Summit Europe in Vienna next week, be sure to catch these sessions.

I am a panelist on the “Improving the Software Supply Chain” along with Tom Hennen from Google, Arnaud Le Hors from IBM, and Aeva Black from CISA. We’ll be discussing various projects under the OpenSSF and CNCF umbrellas, including GUAC, SLSA, and S2C2F. We’ll discuss what those names mean and how the open source communities behind them help improve software supply chain security. Join us on Tuesday at 11:00 CEST in room 2.15.

As you roam the expo hall, stop by the OpenSSF booth between 1:30 and 2:30 PM Monday through Wednesday. I’ll be there to chat and give GUAC demos. Stick around after Open Source Summit for the OpenSSF Community Day. I hope to see you there!

GUAC v0.8.4 is now available. This is a bugfix release. Astute readers will notice that there was no announcement for version 0.8.3. Shortly after 0.8.3 was released, we received reports that the rate limit was not working correctly with the deps.dev service. Version 0.8.4 fixes this on top of the other changes in the 0.8.3 release.

This release includes several fixes to SBOM parsing, including adding a documentRef attribute into client operations that reference hasSBOM and supporting the presence of multiple package URLs in SPDX SBOM externalRefs. It also has database fixes to add a connection timeout and to enable successful altas migration when ENT auto migration was used to create the initial database.

The GitHub release page has a complete list of changes in this release. Want to contribute to GUAC? You can join our community.

Software is only useful when people can use it. We know GUAC is capable of addressing many problems people have securing their software supply chain, so we want to make sure it’s as usable as possible. To do that, we want to talk to you. We’d like to have a short call with you if you:

• Have read the GUAC landing page
• Are NOT a current power user of GUAC
• Tried to go through some of the GUAC demos (optional)

We want to learn what you’re doing today to secure your software supply chain, what your pain points are, and how GUAC could help you address them.

If you’re willing to have a chat with us, email ben@kusari.dev.

If you’ve already tried GUAC and have feedback, please let us know.

Securing the software supply chain is paramount for the Guidewire Cloud Platform (GWCP). More than 540 insurers in 40 countries use GWCP and other Guidewire solutions to run insurance suite applications. GWCP uses GUAC to stay ahead of threats.

Anoop Gopalakrishnan, VP of Engineering at Guidewire, said:

To us, the biggest value is GUAC’s open nature and the community behind it. The advantage we see with GUAC is its flexibility and plugin architecture, which helps users achieve SLSA compliance at difference levels.

Read the case study to learn more about how Guidewire Software uses GUAC.

GUAC v0.8.2 is now available. This release contains improvements to queries and database migrations.

The ClearlyDefined certifier now batches queries in order to speed performance. Calls to ClearlyDefined, OSV, and deps.dev are now rate-limited. The limits follow the service provider’s guidance. Rate limiting ensures that GUAC users get full responses and prevents GUAC from overloading information providers.

Version 0.8.2 also includes an image for Atlas migrations. This will enable seamless migrations to the Ent database layer when the schema changes across versions. Users upgrading persistent installations of version 0.7.0 and earlier will still need to run the migration script prior to upgrading to version 0.8.0 and later.

The GitHub release page has a complete list of changes in this release.

The schedule for our regular GUAC Time office hours is changing. In order to simplify the schedule, we’ll start hosting GUAC Time at 11 AM Eastern on alternating Fridays. The new schedule begins this coming Friday (30 August). The OpenSSF calendar has the updated information.

We’re making this change so that it’s easier for everyone to remember when the office hours are. We chose 11 AM Eastern becuase it keeps the meeting from being too early for community members on the west coast of the Americas and too late for those in Europe.

GUAC Time is an informal “office hours” setting where you can drop in to talk about what you’re working on, ask questions, or have any other GUAC conversations. Everyone is welcome to join, including and especially those who are new to GUAC or the software supply chain security space more generally. We hope you’ll join us!

GUAC v0.8.1 is now available. This release contains a compatibility-breaking change to the database schemea. It also includes several bug fixes and enhancements.

v0.8.1 makes a change in the update dependency schema to require dependencies be specified on a version, not just a package name. This will break persistent installations of version 0.7.0 and earlier. To upgrade to version v0.8.1, run the migration script prior to upgrading GUAC.

GUAC now returns hasSBOM and hasSLSA identifiers at ingenstion time. This simplifies running subsequent queries or as a starting point for GUAC analysis.

This release also fixes bugs in some deps.dev queries and CycloneDX SBOM parsing. For a full list of changes, see the GitHub release page.

Join the GUAC community Thursday at 1PM Eastern (1700 UTC) for the August Community Meeting.

Topics include:

• Demo of the new ClearlyDefined integration
• Discussion of a user journey survey
• An update on a breaking change for re-ingesting SBOMs
• Your expectations for ingestion time
• Demo SBOM latest and vulnerability retrieval via REST API
• end-to-end test updates

If you have your own topics to discuss or cool GUAC insights, join us and share with the community!

Calling all docs writers: we need you! Good documentation makes all of the difference when trying out a new piece of software. Supply chain security is important, so anything we can do to make GUAC easier to use helps us all.

What we’re looking for

We’ve made a start on GUAC’s documentation, but we’re not documentation experts. You are. We need your help to make the docs useful to people trying out GUAC or using it in production.

I opened some issues in the guac-docs repo to help get the process started. This is not an exhaustive list, of course. In fact, the issues that we haven’t identified are the most valuable area for your expertise.

We’d love to have you stick around the community long-term, but you don’t need to sign up for a long-term commitment. One-time fixes of any size are welcome. After all, incremental improvement is still improvement.

About our docs

GUAC’s documentation published to docs.guac.sh from the guacsec/guac-docs repo on GitHub. The docs themselves are written in Markdown and rendered with Jekyll and the Just the Docs theme. Contributions to the GUAC documentation is governed by the OpenSSF Code of Conduct.

If you see something on the main GUAC website, we’re happy to accept those reports and contributions, too. See the guacsec/guac-landing repo on GitHub.

Join the community!

If you see a place you want to contribute, join right in! If you have questions, the GUAC Community is happy to help. Join us in #guac on the OpenSSF Slack.

GUAC v0.8.0, which was released last week, includes the addition of a new data source for GUAC users: license data from ClearlyDefined. While GUAC previously supported reading license information from software bills of materials (SBOMs), adding support for ClearlyDefined represents a big step forward. ClearlyDefined provides a vetted and accurate representation of license information for a given release of software.

Software licenses aren’t strictly a security concern, but they’re a key fact about your dependencies. Full software supply chain observability includes knowing the licenses in your supply chain, which helps you ensure you’re following license terms and your organizational requirements.

How GUAC uses ClearlyDefined

GUAC maintainer Parth Patel decided to implement ClearlyDefined support as a certifier instead of a collector in order to ensure GUAC re-runs the query. GUAC certifiers run on a scheduled basis to capture up-to-date information that may have changed since the last run. License data is always incomplete because developers are always shipping new software releases, so this regular query ensures GUAC captures new license information. If you choose, you can also have GUAC query ClearlyDefined when you ingest a new SBOM, although this does slow down the ingestion process.

GUAC is a tool for giving the information you need to make decisions, not to make decisions for you. As a result, GUAC does not try to guess which response is accurate if the information in the SBOM and the information from ClearlyDefined conflict. Both result in the creation of a CertifyLegal node in the graph, so you can decide which is more trustworthy on a case-by-case basis.

Internally, GUAC uses package URLs (pURLs) to identify specific software package releases. However, ClearlyDefined uses a scheme they call “coordinates”. Part of implementing support in GUAC meant developing a library to convert pURLS to coordinates. Working with the ClearlyDefined community, Parth was able to develop a reference for mapping between the two systems. In a great example of cross-community collaboration, ClearlyDefined added comprehensive documentation for coordinates based on Parth’s work.

One note of caution: ClearlyDefined’s API does not currently support batched queries. As a result, processing large dependency graphs may take longer due to rate limiting. Issue #1168 is open to add batched queries.

About ClearlyDefined

Started at Microsoft, ClearlyDefined is now an incubating project within the Open Source Initiative (OSI). ClearlyDefined provides a centralized, curated source of information about software licenses. The community takes public contributions and evaluates them in an open manner, resulting in a trusted source of information. In addition, ClearlyDefined’s harvester services automatically search for license information when the ClearlyDefined service receives a request it can’t answer. This helps fill the gap in information when a software producer does not include license information in an SBOM.

How you can help

If you have a use case that’s well-served by this new feature, we’d love to hear about it. If you have a use case that isn’t well-served, we want to know that, too. Let us know in a GitHub issue, on Slack, or in one of our regular meetings. See the Community page for more information. We also welcome your contribution of new features to help expand GUAC’s capabilities.

The ClearlyDefined project is looking for contributions to code and license information. See their “Get involved” documentation for more information.

GUAC v0.8.0 is now available. This release brings support for license information, node deletion, and many other improvements. You can now run vulnerability scans immediately on SBOM ingestion with the --add-vuln-on-ingest flag instead of waiting for the OSV certifier to run. To better represent the real world, the isDependency relationship now only exists on package versions instead of the package name. For a full list of changes, see the release page on GitHub.

License information support

GUAC v0.8.0 adds support for parsing license information provided in CycloneDX SBOMs. The new release also includes a new experimental ClearlyDefined certifier. GUAC will query the ClearlyDefined license data store to discover license information for packages, even when the SBOM does not include that information.

Although licenses don’t directly impact security, they are an important part of understanding your software supply chain. We’re excited to expand GUAC’s capabilities in this area.

Node deletion

GUAC v0.8.0 adds support for deleting the following evidence nodes: certifyVuln, hasSBOM, and hasSLSA. This is helpful when SBOMs were ingested by accident or as part of a short-term demo. Delete is supported in both the key value and the ENT backends. If there are other nodes that you have a use case for deleting, please file an issue to let us know.

Understanding and maintaining your software supply chain can be a task that needs 24/7 vigilance. The recent report from Sonatype: State of the Software Supply Chain has shown that supply chain attacks are on the rise (742% average annual increase in the past 3 years). Along with the fact that 6 out of the 7 project vulnerabilities come from transitive dependencies, the industry is in desperate need of having a clear, holistic understanding of the software supply chain.

Supply chain security is at the fore of the industry’s collective consciousness. We’ve recently seen a significant rise in software supply chain attacks, a Log4j vulnerability of catastrophic severity and breadth, and even an Executive Order on Cybersecurity.
