Lock Down the Software Supply Chain With 'Secure by Design'

The report discusses the growing importance of secure-by-design/default principles, driven by escalating supply-chain risks, and highlights CISA’s initiative to embed security throughout the software development life cycle. It emphasizes architectural risk management, defense-in-depth, fuzzing, timely patching, and SBOM-driven transparency; addresses challenges with IoT and long-lived devices; and advocates for practical measures like MFA, eliminating default passwords, and streamlined firmware updates, framing secure development as a shared responsibility and competitive differentiator.
