Your Kubernetes Ingress is the front door to your cluster, and every open path is a possible breach. Managing that surface by hand is a gamble. The only way to control it at scale is to define Kubernetes Ingress security as code.
Ingress defines how external traffic reaches your services. Without clear security policies, you expose routes you didn’t plan, leave TLS misconfigured, or allow unverified hosts. Attackers target mismanaged Ingress rules because they often bypass network policies.
Security as code replaces guesswork with versioned, testable definitions. Store Ingress configurations in Git. Control annotations for rate limiting, whitelisting, HTTPS enforcement, and request size limits. Enforce host validation and strip unneeded HTTP methods. Define TLS secrets and ensure they are consistent across environments. Use linting and policy tools like OPA Gatekeeper or Kyverno to block insecure manifests before they reach the cluster.
