GitHub Elevates Code Provenance to Defend Against Supply Chain Attacks

In a recent discussion at Gartner’s Security & Risk Management Summit, GitHub’s Jennifer Schelkopf highlighted the growing hazard of software supply chain attacks—an issue forecasted to impact nearly half of all organizations by year’s end—as threat actors increasingly target popular open‑source components. She explained that inspecting the origin of code artifacts can significantly disrupt such attacks by eliminating implicit trust in builds.

Schelkopf emphasized the use of the Supply-chain Levels for Software Artifacts (SLSA) framework, which provides structured integrity controls through artifact attestation—detailing where, how, and by whom code was built. She pointed to Sigstore and Kubernetes’ OPA Gatekeeper as key tools that automate signing and verification within CI/CD pipelines, ensuring any tampering is caught before deployment.

Provenance and attestation shift software development from a trust-based model to a trust-verified one. According to Schelkopf, rigged builds—such as those involved in the SolarWinds breach—could have been prevented if artifact attestations had been in place. This approach, she argued, gives defenders confidence that every production-ready artifact is trustworthy and transparent.

OWASP SAMM Skills Framework Enhances Software Security Roles

The OWASP SAMM Skills Framework, introduced on February 9, 2025, is a new initiative donated by Siemens to enhance software security practices within organizations. This framework assigns specific responsibilities to SAMM (Software Assurance Maturity Model) streams, clarifying which roles are involved in advancing each stream. It provides guidance on the necessary skills and training for each role, aligning SAMM-related activities with appropriate stakeholders and their required competencies. This alignment helps organizations identify the right personnel and visualize shared responsibilities, ensuring a structured approach to secure product development. Implementing the OWASP SAMM Skills Framework involves several key steps. Organizations must first map responsibilities to roles, ensuring each task is assigned to the right individual. Next, they must evaluate and align stakeholders with specific SAMM streams, validating that those assigned understand and accept their roles in advanci...
