How do I configure JWT authentication for Envoy Gateway?▼

To configure JWT authentication for Envoy Gateway, you create a SecurityPolicy Custom Resource that targets your Gateway or HTTPRoute and defines the JWT validation rules, applying route-level or gateway-level access control.

What is the best way to enforce OIDC authentication on an HTTPRoute?▼

The best way to enforce OIDC authentication on an HTTPRoute is by attaching a SecurityPolicy CRD to the route, providing the OIDC provider details and referencing Kubernetes Secrets for client credentials to secure web applications.

Can I use SecurityPolicy to apply API Key and Basic Auth on Envoy Gateway?▼

Yes, SecurityPolicy can apply API Key and Basic Auth on Envoy Gateway by defining the respective authentication methods within the policy and targeting either Gateway-level or Route-level traffic for flexible access control.

Does Envoy Gateway SecurityPolicy support delegating authorization to external services?▼

Yes, Envoy Gateway SecurityPolicy supports delegating authorization to external services using ExtAuth, allowing you to configure provider settings and route traffic to external ExtAuth services for custom validation logic.

How do I add CORS and authorization rules to an Envoy Gateway SecurityPolicy?▼

You add CORS and authorization rules to an Envoy Gateway SecurityPolicy by including optional CORS configurations and claims-based access control rules within the YAML manifest, applying unified policy enforcement across targeted routes.

Do I need Kubernetes Secrets to configure OIDC in Envoy Gateway?▼

Yes, you need Kubernetes Secrets to configure OIDC in Envoy Gateway because the SecurityPolicy requires referencing these Secrets to securely store and provide client credentials for the OIDC authentication provider.
