-Open source libraries constitute a significant portion of the world’s digital infrastructure. Securing the Open Source supply chain (OSSC) is therefore an increasing concern, with examples of sophisticated attacks against the ecosystem (e.g., the 2024 [`xz` utils backdoor](https://en.wikipedia.org/wiki/XZ_Utils_backdoor)) and [malware attacks on PyPI](https://blog.pypi.org/posts/2024-04-10-domain-abuse/) highlighting the need for supply chain security to be taken seriously.

 The Python Software Foundation (PSF) is also taking the importance of the OSSC seriously, as demonstrated by the [creation of the PSF Security Developer in Residence position in 2023](https://pyfound.blogspot.com/2023/06/announcing-our-new-security-developer.html).
 
 With the [Supply-chain Levels for Software Artifacts (SLSA) framework](https://slsa.dev/) and [OpenID Connect (OIDC)](https://openid.net/developers/how-connect-works/) standard being widely adopted, several high level developer tools, maintained by professional security teams, have been created with clear recommendations on how to use them.
