The Open Source Security Foundation (OpenSSF) has announced the release of Supply-chain Levels for Software Artifacts (SLSA) v.1.0 with structure changes designed to make the software supply chain security framework more accessible and specific to individual areas of the software delivery lifecycle.
SLSA is a community-driven supply chain security standards project that outlines increasing security rigor within the software development process. It aims to address critical pieces of software supply chain security, giving producers, consumers, and infrastructure providers an effective way to assess software security and gain confidence that software hasn’t been tampered with and can be securely traced back to its source. is backed by several high-profile technology organizations including Google, Intel, Microsoft, VMware, and IBM. The stable release of the SLSA 1.0 lowers the barrier of entry for improvements, helps users focus efforts on improving builds, and reduces the chances of tampering across a large swath of the supply chain, OpenSSF said.
