GUAC mailing lists moving to OpenSSF

The GUAC mailing lists are moving from Google Groups to the OpenSSF list server. Join GUAC@lists.openssf.org to continue receiving updates and participating in the conversation. This list is open for all community discussion of GUAC. The Google Groups list will enter read-only mode after the July 18 GUAC Community Meeting.

The GUAC maintainer list is also moving. Use GUAC-maintainers@lists.openssf.org to report security issues or other confidential concerns to the maintainers.

We look forward to chatting with you on the mailing list and in #GUAC on the OpenSSF Slack.


GUAC v0.7.0 released

The GUAC maintainers are happy to announce the release of GUAC v0.7.0. This release includes several pagination features in order to improve the performance of large result sets from queries. Also new in v0.7.0, the collector supports reading from a directory inside an Amazon S3 bucket, in addition to the previously supported single file and whole-bucket reads. We’ve improved the parsing of CycloneDX files to improve how transitive dependencies are represented. And building off of the persistent backend added in v0.6.0, the new release adds support for automatic schema migrations.

As always, we thank the community members who contributed to this release. We’d love to have you join the GUAC community. See the Contributor Guide for how to get started, and register for an upcoming program below.


GUAC maintainer meetings now public

In the interests of a transparent open source community, the weekly GUAC Maintainer meetings are now public. Join us on Mondays at 11 AM Eastern. The meeting is open to interested community members, but is primarily for maintainer discussion. For general questions and discussion, join us in #guac on the OpenSSF Slack.


Upcoming OpenSSF and CNCF webinars

Terror of cURL - Preparation is half the battle

Last week, on October 11th, we finally found out more information on the high-severity CVE that affected numerous versions of cURL. Everyone was waiting in dreaded anticipation to determine if they were affected or not!

GUAC allows you to be proactive in responding to threats without waiting for the CVEs to be released, reducing the MTTR significantly! In our latest combined blog with Brandon Lum and Mihai Maruseac, we discuss this in greater detail and provide insight.

Quest to determine the 'G' in GUAC

As we work to meet the goals of persistence in GUAC, we are running a series of analyses and comparisons among the many different graph database options. GUAC has a few critically important requirements for the backend, including: efficient ingestion of data, performant complex queries, the schema in which the data is stored, and finally optimization of the query based on the specific language.

A high fidelity view of software supply chain

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.


Announcing GUAC, a great pairing with SLSA (and SBOM)!

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.
