One of the biggest challenges for software developers is the need to make informed choices about the external software and products they use in their own software systems. Evaluating whether a given system is appropriately secured can be challenging, especially if it’s external or owned by a third party.
This so-called software supply chain has been under increasing scrutiny in recent years, with attacks on software systems being responsible for damages to both public and private interests. In collaboration with the Open Source Security Foundation (OpenSSF), Google has proposed Supply-chain Levels for Software Artifacts (SLSA). The new SLSA framework formalizes criteria around software supply chain integrity, to help the industry and open-source ecosystem secure the software development lifecycle.
SLSA (pronounced “salsa”) is a security framework from source to service, giving anyone working with software a common language for increasing levels of software security and supply chain integrity. It’s how you get from safe enough to being as resilient as possible, at any link in the chain.
This SlideShare explores the concept of SLSA in brief.
