GUAC v0.14.0 released

GUAC v0.14.0 is now available. This release adds:

  • Kubescape collector
  • Improvements to the ClearlyDefined certifier
    • Retry failed requests for more error codes
    • Improve Go package name translation
  • Endpoint changes to REST API
    • Dependency search queries are now under the versioned “/v0/…” path
  • Improvements to the End of Life certifier logic
    • The parsing of purls now uses standard helper methods and the check for whether a node has EOL data is now more specific to mitigate false positives
  • Connect equivalent nodes representing container images with an IsOccurrence node.

The v0.14.0 release page has full details of this release. If you’re interesting in joining our community or contributing, we’d love to have you be a part of the next release.

GUAC now supports runtime Kubernetes SBOMs using Kubescape

With the release of GUAC v0.14.0, GUAC includes a Kubescape collector that can be run inside your Kubernetes cluster to watch for new scan results from Kubescape and ingest those results into the GUAC supply chain graph.

Kubescape is an open-source Kubernetes security platform that provides comprehensive security coverage, from left to right across the entire development and deployment lifecycle. It offers hardening, posture management, and runtime security capabilities to ensure robust protection for Kubernetes environments.

When Kubescape is installed as an Operator in your Kubernetes cluster, it can continuously scan all running containers for contents and vulnerabilities. These scan results can be accessed as Kubernetes API server custom resources. Additionally, Kubescape can filter the SBOM scan results based on relevancy based on eBPF observation.

With GUAC being the prime system resource for collating and correlating data from across your supply chain, it only made sense to enable GUAC to incorporate these Kubescape results. GUAC’s new ability to analyze both build-time and run-time SBOMs in a single GraphQL API enables exciting new insights. We will explore some of those in our Kubecon EU session “Why Don’t We Have Both? Track Build- and Run-time Information for Security With Kubescape and GUAC”. Please join us there or look out for the recording.
