The firewall was silent, but the logs told another story. Ingress traffic was breaching the perimeter, and every byte carried potential risk. When handling Protected Health Information (PHI), you cannot afford mistakes. HIPAA compliance demands clear control over ingress resources — the Kubernetes objects that define how external requests enter your cluster.
Hipaa ingress resources are more than routing rules. They are gateways enforcing encryption, authentication, and strict access to services handling PHI. Misconfigured ingress can expose endpoints to unauthorized access, violate audit requirements, and trigger costly penalties. Every rule, certificate, and annotation matters.
Security starts with TLS termination. HIPAA requires encryption in transit. Your ingress resource must enforce HTTPS with strong cipher suites. Certificates should be managed securely, rotated often, and validated before deployment. Avoid self-signed certs in production.
Role-based access control is next. Limit who can update ingress resources. Internal changes should be logged. Controllers like NGINX or Traefik must be hardened, monitored, and patched against known CVEs. An unpatched ingress controller is a compliance failure waiting to happen.
