Introducing Software Delivery Shield For End-To-End Software Supply Chain Security

 Organizations and their software delivery pipelines are continually exposed to growing cyberattack vectors. Coupled with the massive adoption of open source software, which now helps power nearly all of our public infrastructure and is highly prevalent in most proprietary software, businesses around the world are more vulnerable than ever. Today’s organizations need to be more vigilant in protecting their software development infrastructure and processes. Development and IT teams are all asking for a better way to secure the software supply chain across the code, people, systems, and processes that contribute to development and delivery of the software.For many years, Google has been working with the developer community, the public sector, and our partners to establish industry-wide standards and frameworks, like Supply Chain Levels for Software Artifacts (SLSA), for enhancing software supply chain security. And just last year, as part of Google’s $10 billion commitment to advancing cybersecurity, we pledged to protect key open source components that are crucial to the health of our public infrastructure and companies around the world.

Answering the software supply chain security call

To further help our customers improve their software supply chain security, we’re now excited to announce Software Delivery Shield. This is a fully managed software supply chain security solution that offers a modular set of capabilities to help equip developers, DevOps, and security teams with the tools they need to build secure cloud applications. Software Delivery Shield spans across a family of Google Cloud services from developer tooling to runtimes like GKE, Cloud Code, Cloud Build, Cloud Deploy, Artifact Registry, Binary Authorization, and more.

Software Delivery Shield includes capabilities across five different areas to address security concerns along the software supply chain: application development, software “supply,” continuous integration (CI) and continuous delivery (CD), production environments, and policies. It also allows for an incremental adoption path, so organizations can tailor the solution to their specific needs, choosing the preferred tools to start with based on their existing environment and security priorities.

Develop fast, securely

To help protect software from the beginning — at the development stage — we’re excited to introduce a new service in Preview at Google Cloud Next: Cloud Workstations, which provides fully managed development environments on Google Cloud. With Cloud Workstations, developers can access secure, fast, and customizable development environments via a browser anytime and anywhere, with consistent configurations and customizable tooling. At the same time, IT and security administrators can easily provision, scale, manage, and secure the development environments on Google Cloud’s infrastructure.

A critical part of Software Delivery Shield, Cloud Workstations plays a key role in “shifting security to the left,” by enhancing the security posture of the application development environment. With built-in security measures such as VPC Service Controls, no local storage of source code, private ingress/egress, forced image updates and IAM access policies, Cloud Workstations helps address common local development security pain points like code exfiltration, privacy risks, and inconsistent configurations.

In addition to helping secure dev environments with Cloud Workstations, we’re also giving developers tools to code fast and more securely from their laptops. Cloud Code, our family of IDE plugins, now features Source Protect in Preview. Source Protect gives developers real-time security feedback as they work in their IDEs, identifying issues such as vulnerable dependencies and license reporting. This kind of quick and actionable feedback can allow developers to promptly make corrections to their code, saving time from costly future fixes.

Safeguard the software ‘supply’

Securing the software supply — build artifacts and application dependencies — is another critical step in improving software supply chain security. The pervasive use of open source software makes this problem particularly challenging.

While working together with the broader community on establishing guidelines and frameworks to increase open source security as a whole, we are also bringing more services to help address this challenge directly. In May, we introduced Assured Open Source Software service, currently in Preview. Assured OSS is Google’s first “curated” open source where we are adding a layer of accountability on top of today’s free or “as-is” open source. A key part of the Software Delivery Shield solution, Assured OSS provides access to open source software packages that have been curated and vetted by Google. These packages are built in our secured pipelines and are regularly scanned, analyzed, and fuzz-tested for vulnerabilities. With Assured OSS, the security team can be much more confident knowing their developers are using vetted open source dependencies. This service now provides over 250 curated packages across Java and Python, with verified provenance. It automatically generates Software Bill of Materials (SBOM) – an inventory of all components and dependencies involved in the application development and delivery – identifying where there could be a potential risk.

With Software Delivery Shield, DevOps teams can store, manage and secure the build artifacts in Artifact Registry, and also proactively detect vulnerabilities with the integrated scanning provided by Container Analysis, to which we’ve added support for more language packs. In addition to scanning the base images, it can now do on-push vulnerability scanning of Maven and Go containers, as well as for non-containerized Maven packages (currently in Preview).

Lock down the CI/CD pipeline

Bad actors can attack software supply chains by compromising CI/CD pipelines. That’s why we’re always working to strengthen the security posture of our CI and CD platforms – Cloud Build, our fully managed CI platform, and Cloud Deploy, our fully managed CD platform. As key parts of the Software Delivery Shield solution, both platforms come with built-in security features such as granular IAM controls, VPC Service Controls, isolated and ephemeral environments, and approval gates to help DevOps teams better govern the build and deployment process.

Cloud Build now officially supports SLSA Level 3 builds, implementing SLSA level 3 best practices by default. In addition to providing ephemeral and isolated build environments, Cloud Build can now generate authenticated and non-falsifiable build provenance for both containerized applications and non-containerized Maven and Python packages, as well as display security insights for built applications.

Help protect applications in production

Strengthening the security posture of the runtime environments is another critical part of securing the software supply chain. Google Kubernetes Engine (GKE) and Cloud Run, our leading runtime platforms for containerized applications, both come with baked-in security features to help protect applications while they are running.

We’re excited to announce new built-insecurity posture management capabilitiesfor GKE, currently in Preview, to help identify and fix security concerns in GKE clusters and workloads. Based on industry standards and the GKE team’s security expertise, GKE now provides detailed assessments, assigns severity ratings, and advises on the security posture of the clusters and workloads, including insights into OS vulnerabilities and workload configurations.The GKE dashboard now clearly points out which workloads are affected by a security concern and then provides actionable guidance to address it. Beyond the dashboard, GKE can also log security posture concerns to Cloud Logging, while security event information can be routed to services like the ticketing systems or a security information and event management (SIEM) system through Pub/Sub eventing.

For customers of our Cloud Run serverless platform, we are introducing new enhancements to Cloud Run’s security panel. It now displays software supply chain security insights such as SLSA build-level compliance info, build provenance, and vulnerabilities found in running services (currently in Preview).

Build a chain of trust through policy

Beyond enhancing the security posture at each stage of the software delivery lifecycle, Software Delivery Shield features a trust-based policy engine to help establish, maintain, and verify a chain of trust across the entire supply chain.

Binary Authorization is a deploy-time security control that can ensure only trusted container images are deployed on GKE or Cloud Run. With Binary Authorization, DevOps or security teams can require images to be signed by trusted authorities during the development process and then enforce signature validation when deploying. By enforcing validation, they can gain tighter control over the container environment by ensuring only verified images are integrated into the build-and-release process.
