Description

The Pathways to Enable Secure Open-Source Ecosystems (PESOSE) program supports the translation of open-source science and engineering-focused research products into safe and sustainable ecosystems that address national and societal challenges. It focuses on open-source tools such as software, hardware, machine learning models, languages, and data platforms that are publicly accessible and modifiable. The program supports the creation of managing organizations for these ecosystems to ensure strong governance, distributed development, and broad user communities across academia, industry, and government. It also aims to enhance the safety, security, and privacy of Open-Source Ecosystems by addressing significant vulnerabilities to improve resistance against threats. The solicitation seeks proposals to scope and plan, establish and expand, or improve the safety and security of open-source ecosystems.
