JFrog’s Role in Securing the Software Supply Chain Across CI/CD Pipelines

One vulnerable library can enter your build in silence through testing and become part of your release before it makes its way into production. Once you discover it, the vulnerable library is already running in customer environments. Modern software development is such that software delivery has to be very fast, the number of dependencies has exploded, and trust is often assumed rather than verified.

In this article, we look at why software supply chain security has become a priority, how dependencies and build artifacts cause vulnerabilities, and how teams can establish visibility, integrity, and control throughout their CI/CD pipeline using JFrog.

Why software supply chains are now a security hotspot

Most modern software is not developed from the ground up, but rather by stitching together multiple systems (hundreds) of developers (open source libraries), or other people (containers), or third parties (binaries). Although they can help to speed the development process, they will also help to create a larger attack surface.

Attackers do not need to directly breach your application anymore. They can breach your upstream dependencies, compromise your build systems, or insert malicious code into legitimate artifacts. When those artifacts traverse your CI/CD pipeline, they become trusted.

With this shift in the attack methods, the security of artifacts has now become just as important as code security; therefore, all binaries, container images, and packages must be considered possible entry points.

How vulnerabilities enter through artifacts and dependencies

There are three common ways risks enter the software supply chain.

Compromised or vulnerable dependencies
Open source packages may include known vulnerabilities or hidden malicious code. If your build pulls these automatically, the risk flows straight into your application.

Unverified builds and binaries
When artifacts are created without strong verification, there is no guarantee that what you deploy matches the source code. A compromised build agent or pipeline can inject changes that go unnoticed.

Lack of traceability and visibility
Without a clear record of where each artifact came from and what it contains, teams struggle to respond when a new vulnerability is discovered. This delay increases the blast radius of any incident.

Why artifact management is central to DevSecOps

Security teams frequently prioritize scanning their source code; however, the actual artifact or the real “unit” of deployment is the build output. Thus, the storage, versions/comparators of your artifacts become a key controlling point.

By having a solid management plan in place for your artifacts builds, you’ll track every single build output, verify it within policy, and provide consistent security checks for all of the aforementioned items before moving them into the next stage of your pipeline.

How JFrog secures the software supply chain

JFrog is an end-to-end CI/CD solution that sits as the hub for your CI/CD process, providing one single source of truth for all of your artifacts while providing security, traceability, and enforcement of policies throughout the entire lifecycle of an artifact.

Centralized artifact repository

JFrog Artifactory acts as a centralized repository to store all of your binaries, containers, and packages, and ensures that your teams are always pulling dependency code from a known and trusted source – not arbitrary public registries. Furthermore, JFrog Artifactory provides visibility into all dependencies used across projects.

Deep security scanning with context

JFrog Xray continuously scans your artifacts for vulnerabilities, licensing issues, and misconfigurations, providing a complete solution. More importantly, JFrog Xray provides context for each vulnerability, allowing you to see where a vulnerable component has been utilized within your application and the relevance in relation to your application. This will allow teams to prioritize the issues that are most relevant to their needs.

Integrity verification and provenance

JFrog provides various integrity verification methods, such as checksum validations, signed artifacts, and build information tracking. By providing these means of verification, JFrog creates a verifiable chain of custody from the source code to the deployed binary. Teams can prove that an artifact was built from a specific commit and has not been altered or tampered with during the process.

Policy enforcement in CI/CD pipelines

Security policies can be defined and automatically enforced during builds and releases. For example, a pipeline can block any artifact that includes a critical vulnerability or an unapproved license. This shifts security left without slowing down developers.

Real-world DevSecOps scenarios where visibility matters

When a team develops a microservices platform that utilizes numerous container images, one of those base images can have an OpenSSL version that contains vulnerabilities. Thus, if there is no central view of all microservice layers created by each service team, these teams could inadvertently deploy duplicate, vulnerable layers into their services. 

The security group within JFrog can utilize a single vulnerability discovery to identify all affected artifacts and prevent any further promotions on that item until a resolution has been provided. By doing this, the security group will eliminate the issue before it reaches production.

In another example, if a company uses a library provided by another vendor and that library is later identified as providing malicious results, the organization will be able to pinpoint every build that was conducted with that library by leveraging the fact that all artifacts/dependencies are tracked in Artifactory, including the associated metadata. Therefore, the company would be able to implement a safe replacement for all builds that utilized the original.

Additionally, there are variations in which a build pipeline could offer a compromised build. For example, if code is injected by a malicious user within the building phase of a pipeline, verifying checksums and utilizing signed artifacts will help detect any differences between the expected and actual output. By performing this verification on all artifacts in Artifactory, the company can prevent the distribution of compromised artifacts.

Best practices for securing your artifact pipeline

To reduce risk across the supply chain, teams should follow a few core practices.

• Use a single trusted artifact repository for all dependencies and build outputs.
• Verify artifact integrity with checksums and digital signatures.
• Scan all artifacts continuously, not just source code.
• Track full build metadata so every artifact can be traced back to its origin.
• Enforce security policies automatically within CI/CD pipelines.
• Limit access and permissions to artifact repositories to prevent unauthorized changes.

When these practices are combined with a platform like JFrog, security becomes part of the delivery workflow instead of a last-minute check.

The path forward for secure software delivery

Supply chains will continue to be an area of focus for attackers as the software supply chain expands. By implementing artifact security as a first-class concern, you will be better positioned to deal with the increased volume of emerging threats companies will face.

JFrog enables teams to move from a reactive security posture to proactively controlling their software supply chain by providing visibility into every component that flows through their pipeline. This visibility allows teams to respond more quickly, increase compliance, and feel confident in their releases.

If you are currently developing software applications and want to protect your supply chain from hidden risks, now is the time to improve your artifact security strategy. Learn how JFrog can fit into your CI/CD workflow and start building a trusted supply chain.
