As we start to pay more attention to software supply chains (thank you, SBOM!), an old problem has resurfaced with a vengeance: how do we identify a particular piece of software? The software world - and the US government - has a goal for automation and easy mapping from a software dependency list to lists of known badness (vulnerabilities, potential malicious back doors, less optimal development practices, etc.). However, this requires a common namespace and shared identifiers for software. The current challenge is not that lack of naming standards, it is that we have several, and there are large gaps between them. This talk will describe the challenges presented regarding software identifiers as we try to secure the software supply chain. We’ll review existing solutions (CPE! PURL! Device identifiers! Hashes!), potential risks, and lay out a collaborative patch to addressing this over time and how the open source community can help and get involved.
