OpenSSF Announces Initial Release of the Open Source Project Security Baseline

New Initiative Aims to Enhance Open Source Software Security Through Tiered Best Practices

SAN FRANCISCO, Feb. 25, 2025 /PRNewswire/ -- The Open Source Security Foundation (OpenSSF) is pleased to announce the initial release of the Open Source Project Security Baseline (OSPS Baseline). The Baseline initiative provides a structured set of security requirements aligned with international cybersecurity frameworks, standards, and regulations, aiming to bolster the security posture of open source software projects.

"The OSPS Baseline release is a significant milestone in advancing security initiatives within the open source ecosystem," said Christopher Robinson, Chief Security Architect at OpenSSF. "We're excited to roll out OSPS Baseline following community testing and validation — we are confident that these security best practices are both practical and impactful across open source projects."

The OSPS Baseline offers a tiered framework of security practices that evolve with project maturity. It compiles existing guidance from OpenSSF and other expert groups, outlining tasks, processes, artifacts, and configurations that enhance software development and consumption security. By adhering to the Baseline, developers can lay a foundation that supports compliance with global cybersecurity regulations, such as the EU Cyber Resilience Act (CRA) and U.S. National Institute of Standards and Technology (NIST) Secure Software Development Framework (SSDF).

"We've gotten helpful feedback from projects involved in the pilot rollout, including adoption commitments from GUAC, OpenVEX, bomctl, and Open Telemetry," said Stacey Potter, Independent Open Source Community Manager, after helping lead the OSPS Baseline pilot efforts. "We know it can be tough to navigate all the security standards out there, so we built a framework that grows with your project. Our goal is to take the guesswork out of it and help maintainers feel confident about where they stand, without adding extra stress. It's all about empowering the community and making open source more secure for everyone!"

"I'm excited to see the release of OSPS Baseline," said Ben Cotton, Open Source Community Lead at Kusari & OSPS Baseline Co-maintainer. "This effort provides actionable, practical guidance to help developers achieve appropriate security levels for their projects. Too often, security advice is vague or impractical, but Baseline aims to change that. Every improvement to open source security strengthens the modern software ecosystem, making it safer for everyone."

OpenSSF invites open source developers, maintainers, and organizations to make use of the OSPS Baseline. Through engaging with this initiative, stakeholders can also contribute to refining the framework and promoting widespread adoption of security best practices in the open source community.
