Securing CI/CD Images with Cosign and OPA
Notary v2: The evolution to Notary v2 brought improvements in signature portability and integration with third-party key management solutions. However, it does not provide a certificate authority, leaving public key discovery for open-source image verification as an unresolved issue.

Level-up Container Security: 4 Open-Source Tools for Secure Software Supply Chain
Notation is another command-line too that lets you digitally sign artifacts. And those signatures essentaily become the stamps of approval for the different things in your software supply chain. For example, container images.
- notaryproject/notation: Notation is a project to add signatures as standard items in the registry ecosystem, and to build a set of simple tooling for signing and verifying these signatures. Based on Notary V2 standard.

Getting Started with Notary
Notary is the CNCF project name and is often referenced when referring to the process of signing digital artifacts, but Notation is the command line tool that does the heavy lifting. Run the following commands to install Notation.

Making the Internet more secure one signed container at a time
It should be interoperable, that's the goal. I proposed some idea for nv2 here: https://github.com/notaryproject/nv2/issues/39 and here: https://github.com/notaryproject/nv2/issues/40 too.

SAP BTP, Terraform and Open Policy Agent
How can we handle this? Are there any mechanisms to prevent or at least to some extent safeguard this kind of issues without falling back to a manual workflow? There is. One huge advantage of sticking to (de-facto) standards like Terraform is that first we are probably not the first ones to come up with this question and second there is a huge ecosystem around Terraform that might help us with such challenges. And for this specific scenario the solution is the Open Policy Agent. Let us take a closer look how the solution could look like.

Top Terraform Tools to Know in 2024
A popular Policy-as-Code tool for Terraform is OPA, everyone's favorite versatile open-source policy engine that enforces security and compliance policies across your cloud-native stack, making it easier to manage and maintain consistent policy enforcement in complex, multi-service environments.

Build and Push to GAR and Deploy to GKE - End-to-End CI/CD Pipeline
Harness Policy As Code uses Open Policy Agent (OPA) as the central service to store and enforce policies for the different entities and processes across the Harness platform. In this section, you will define a policy that will deny a pipeline execution if there is no approval step defined in a deployment stage.

10 Ways for Kubernetes Declarative Configuration Management
OPA: While OPA is an open-source, general-purpose policy engine capable of enforcing unified and context-aware policies throughout the stack, it can also accept and output data in formats such as JSON, effectively functioning as a tool for generating or modifying configurations. Although it does not provide out-of-the-box schema definition support, it allows the integration of JsonSchema definitions.

Securing CI/CD Images with Cosign and OPA
In essence, container image signing involves adding a digital stamp to an image, affirming its authenticity. This digital assurance guarantees that the image is unchanged from creation to deployment. In this blog, I'll explain how to sign container images for Kubernetes using Cosign and the Open Policy Agent. I will also share a tutorial that demonstrates these concepts.
