The Open Source Security Foundation (OpenSSF) has announced the initial release of the Open Source Project Security Baseline, a set of recommendations to help open source projects improve their security posture. The baseline is divided into three levels of increasing rigor, allowing projects to gradually adopt more advanced security practices. The initiative is a response to the growing threat of software supply chain attacks and aims to provide a clear and actionable framework for open source developers to follow. The baseline is available on the OpenSSF's GitHub repository and is open to community feedback and contributions.
