This guide explains how securing modern cloud environments requires bridging the gap between infrastructure-as-code (IaC) and runtime security. It emphasizes shifting security left by scanning IaC early in development (IDE, PRs, CI/CD) to prevent misconfigurations before deployment, while also maintaining visibility into production risks. A key principle is mapping runtime issues back to their source code, ensuring fixes happen in IaC rather than ad hoc patches in the cloud, which cause drift. It also highlights policy-as-code, developer-friendly remediation, and unified enforcement across environments. The main takeaway is that aligning code and cloud security reduces risk, improves ownership, and prevents recurring vulnerabilities.
