Software Supply Chain Security vs. SCA: What’s the Difference?

This article contrasts software supply chain security with Software Composition Analysis (SCA), defining the software supply chain, listing common risks (e.g., unsecured code, third‑party components, distribution channels, pipelines and toolchains), and describing how SCA and SBOMs help discover components, surface vulnerabilities, integrate with repositories, and enforce license compliance. It concludes that SCA is a critical element of supply chain security but should be combined with other controls (SAST, Secrets scanning, IaC checks, pipeline profiling, integrity scanning, and toolchain security) to secure the entire development pipeline.
