Ingress was open, and the security audit showed gaps you can drive a botnet through. Kubernetes Ingress is the doorway into your cluster. If it’s not locked down, every service behind it is at risk.
This is your Kubernetes Ingress security review.
First, map the attack surface. An Ingress Controller like NGINX or Traefik sits between the internet and your services. Every annotation, TLS setting, and routing rule can expose data or allow unauthorized access. Look at path rewrites, default backends, and HTTP vs. HTTPS enforcement. Turn off HTTP unless absolutely required.
Second, run strict TLS.
Use modern ciphers, disable weak protocols, and require certificates from a trusted CA. Automate certificate rotation. Avoid self-signed certificates for public endpoints. TLS must be configured at the Ingress level, not left to individual applications.
Third, restrict access.
Ingress rules should route only to required services. Use network policies to block lateral movement. Limit exposure by deploying multiple Ingress resources—public and internal—so private APIs never touch the public internet.
