OWASP supply chain security cheat sheet: 5 key action items

This report summarizes OWASP’s Software Supply Chain Security Cheat Sheet into five key actions: secure development platforms and enforce strong access controls across IDEs, repositories, and CI/CD; leverage automation for scalable scanning, monitoring, and testing; rigorously assess third-party software and services with continuous visibility (e.g., SBOMs and binary analysis); verify provenance and generate trustworthy build metadata; and scan final build binaries and use reproducible builds to detect tampering. Expert commentary stresses least privilege, hardened developer workstations, signed commits, machine-readable policies, and binary/runtime composition analysis, advocating a systematic, automated approach to mitigate increasingly complex supply chain risks highlighted by incidents such as 3CX.
