Introduction
In the digital age, the security of software is no longer just about preventing attacks on end-user applications. The real risk often lies deeper within the software’s supply chain—the code dependencies, libraries, and artifacts that make up modern applications. Jennifer Schelkopf, director of product management at GitHub, argues that understanding the provenance of the code you use can be the key to mitigating the growing threat of supply chain attacks. During her presentation at the Gartner Security & Risk Management Summit in Washington, DC, she outlined how tools like artifact attestation and the SLSA (Supply-chain Levels for Software Artifacts) framework can help organizations prevent these attacks.
What Are Supply Chain Attacks?
Supply chain attacks happen when malicious actors compromise software at various points in the supply chain. These attacks often target the open-source libraries, frameworks, and dependencies that developers rely on to build applications. Examples like the SolarWinds hack, Log4Shell, and recent incidents with PyTorch’s PyPi repository highlight the danger of these attacks. These attacks can affect millions of users and cause severe damage to an organization’s reputation and infrastructure.
Code Provenance: A Key to Defending Against Supply Chain Attacks
The concept of code provenance refers to understanding and tracking the origin and journey of every piece of code within your software. Knowing where your code comes from, how it was built, and who approved it can help you trust it more fully and prevent malicious code from slipping through the cracks. According to Schelkopf, if software teams can establish solid provenance practices, they can significantly reduce the risk of supply chain attacks.
The Power of the SLSA Framework
One of the most powerful tools in securing code provenance is the SLSA framework. Developed through industry collaboration, SLSA aims to establish best practices for maintaining software integrity throughout its lifecycle. SLSA includes multiple levels of security requirements to ensure that software artifacts are tamper-proof and reliable. By providing guidelines on artifact production, provenance, verification, and security, the framework helps developers create more resilient systems.
In Schelkopf’s words, SLSA turns the concept of “implicit trust” into “explicit trust.” Instead of assuming that all dependencies and code in your pipeline are secure, SLSA offers a structured, verifiable way to ensure they are.
How SLSA Helps in Preventing Malicious Code Injections
In practical terms, the SLSA framework helps prevent supply chain attacks by introducing attestation processes for each artifact used in software development. Through tools like Sigstore and OPA Gatekeeper, developers can automatically sign, verify, and validate code as it moves through the pipeline. This creates a digital paper trail, ensuring that each artifact is authentic, tamper-free, and complies with established security policies.
Schelkopf pointed out that the SolarWinds attack could have been prevented with proper artifact attestation. If the build signature of the malicious code had been flagged, the attack might have been stopped in its tracks. With these automated checks, defenders can have more confidence that the code they deploy is safe.
What Undercode Say:
The rise in sophisticated supply chain attacks over the past few years highlights a fundamental flaw in traditional software development processes: implicit trust. Developers often assume that the libraries and dependencies they use are secure without proper verification. This false sense of security has led to a number of high-profile breaches. The key to addressing this vulnerability lies in shifting to explicit trust, as Jennifer Schelkopf emphasized in her talk at the Gartner summit.
The SLSA framework is designed to address this gap. By implementing standards for artifact integrity, artifact provenance, and verification, SLSA ensures that every component of the software supply chain is trustworthy. Moreover, tools like Sigstore and OPA Gatekeeper automate the verification process, reducing the manual effort required and increasing security at every stage of development.
SLSA’s potential is not just theoretical—it’s practical. Organizations can implement this framework now, ensuring that any software they develop is more resilient against supply chain threats. Attestations can catch malicious code before it reaches production, adding a crucial layer of defense that many organizations are currently missing.
The importance of this shift cannot be overstated. Supply chain attacks have become more common and more damaging, affecting everything from financial institutions to national security. By prioritizing code provenance, software teams can reduce their exposure to these risks and significantly strengthen their defenses against future threats.

Prediction 🧐
With the increasing sophistication of cyber threats, the demand for secure software development practices will continue to rise. Over the next few years, we can expect the adoption of frameworks like SLSA to become standard practice within the industry. Organizations that invest in code provenance and artifact attestation will be better positioned to defend against supply chain attacks, significantly reducing the potential for large-scale breaches. As these practices become more mainstream, they will likely be integrated into development pipelines by default, transforming security from a reactive measure into a proactive, foundational aspect of software engineering.
