Sigstore Proves That Effective Supply Chain Security Doesn’t Have to Hurt

Oct 22, 2022 · Sigstore

This is a Sigstore case study contributed by Brandon Gulla, CTO at Rancher Government Solutions Traditionally, everyone in IT assumed good security had to hurt a little bit. If it didn’t hurt, security wasn’t strong enough. But computing trends in software supply chains have shifted in recent years, moving toward centralized development and software factories. When you have that common infrastructure throughout the organization, you can isolate a lot of that pain within the process — without too much developer interaction and disruption.

Signing and Securing Confidential Kubernetes Clusters in the Cloud with Sigstore

Aug 11, 2022 · Fabian Kammel

This is a Sigstore case study contributed by Fabian Kammel of Edgeless Systems Confidential computing is an exciting new technology that can help make the public cloud more secure. It protects data stored on leased third-party infrastructure and ensures nobody modifies or intercepts it, whether it resides on the cloud or is being routed to or from your internal assets. But it’s also vital that security solutions like those of Edgeless Systems are secure themselves.

Verify cosign signatures in go using sigstore/sigstore

Aug 9, 2022 · Fabian Kammel

After integrating cosign into the release process of Constellation’s CLI, I also wanted to improve the supply chain security of our metadata that are used for attestation. Using cosign CLI for signing and verifying blobs or container images is a well documented process. The sigstore/sigstore project is the common go library for all sigstore services and clients and has documented public functions, but I was unable to find examples on how to use them together.
