10 Policy and Insight
This chapter covers
- Understanding how policy as code and governance as code enable consistent and scalable enforcement of supply chain security practices
- Exploring the benefits and challenges of automating policy enforcement across the SDLC
- Applying policy as code to secure ingestion, ensuring only approved and trusted dependencies are used
- Enforcing best practices within the secure software factory through codified policies
- Leveraging policy as code to ensure compliant deployments and runtime security
- Discussing the tools and technologies available for implementing policy as code, such as Open Policy Agent (OPA) and SLSA
- Tying together all the elements of software supply chain security discussed throughout the book using policy as code and automation
Throughout this book, we have explored various aspects of software supply chain security, from threat modeling and secure ingestion to building a secure software factory and leveraging software metadata. We have seen how each of these elements contributes to a comprehensive strategy for mitigating the risks associated with modern software development. However, implementing these practices consistently and at scale requires a unified approach that ties everything together. This is where policy as code and automation come into play.
