The Open Source Security Foundation (OpenSSF) has released a new security baseline for open source projects. This initiative aims to improve the security posture of the open source ecosystem by providing a clear, tiered set of best practices for project maintainers. The baseline is designed to be adaptable, allowing projects of different sizes and complexities to adopt security measures appropriate to their needs. The release is a direct response to the increasing number of software supply chain attacks and vulnerabilities affecting open source software. By establishing a common set of expectations, the OpenSSF seeks to create a more secure and resilient open source community.
