3.6. Securing HTTPRoutes
To protect sensitive data and meet security compliance requirements, you must secure your Gateway API application traffic. You can secure 'HTTPRoute' custom resources (CRs) by either applying edge or re-encrypt Transport Layer Security (TLS) termination. Choose your method based on your security architecture and performance needs.
3.6.1. HTTPRoute Transport Layer Security (TLS) configuration
To balance security compliance and application performance, you can configure edge or re-encrypt TLS termination on your gateway listeners.
- Edge termination
- Edge termination encrypts client traffic to the gateway but allows unencrypted traffic to pass to your internal services. This configuration is ideal for encrypting user logins while trading internal encryption for faster application performance.
- Re-encrypt termination
- Re-encrypt termination encrypts traffic from the client to the gateway, and then re-encrypts it to the destination service. This mode allows the gateway to inspect payloads to efficiently route traffic or block unauthorized access without eliminating backend encryption.
OpenShift Container Platform does not support passthrough termination for Gateway API. Passthrough termination provides direct traffic encryption from the client to the service, and is only supported in traditional OpenShift Container Platform routes.
