Kubernetes will now add cryptographically signed signatures to protect users and organizations from supply chain attacks.
Access to the cryptographically signed signatures is via the Sigstore project created by the Linux Foundation.
Using sigstore certificates allows Kubernetes users to verify the authenticity and integrity of the distribution they are using.
According to founding Sigstore developer Dan Lorenc, the use of Sigstore certificates gives “users the ability to verify signatures and have greater confidence in the origin of each Kubernetes binary, source code bundle, and container image.”
Lorenc pointed out that Kubernetes’ adoption of Sigstore is part of its work on supply chain levels for Software Artifacts (SLSA). SLSA is a framework developed by Google for the internal protection of its software supply chain.
The Sigstore project is also aimed at Python developers. The aim of this project will be to release a new tool for signing Python packages as well as major package repositories such as Maven Central and RubyGems.
