What it means
Infrastructure-as-code policy enforcement evaluates proposed configurations against security, compliance, resilience, cost, and architecture rules before and after deployment.
Why it matters
Reusable code can reproduce insecure patterns at scale unless policy is automated near the point of change.
Practical focus
- Define the system boundary, accountable owner, approved purpose, material risks, and decision authority for Infrastructure-as-Code Policy Enforcement
- Define testable policies, run checks in development and pipelines, block material violations, govern exceptions, scan deployed state, and version policy with rationale.
- Collect and protect this evidence: policy code, test results, violations, approvals, exceptions, deployed-state scans, and policy-change history.
- Exercise this failure scenario as a planned test: a module opens public network access across every environment because the policy check runs only after deployment and cannot block changes.
Common mistakes
- Using the label Infrastructure-as-Code Policy Enforcement without defining the exact systems, data, people, decisions, and time period in scope
- Treating a policy statement or tool demonstration as proof that Infrastructure-as-Code Policy Enforcement operates consistently in production
- Failing to retain policy code, test results, violations, approvals, exceptions, deployed-state scans, and policy-change history in a form that lets an independent reviewer reconstruct decisions and changes
- Testing only the normal path and never rehearsing what happens when a module opens public network access across every environment because the policy check runs only after deployment and cannot block changes.
