In Istio we usually use two actions for the AuthorizationPolicy: DENY and ALLOW. For example, the following authorization policy applies to workloads matched with label selector “app: httpbin, version: v1”. It fetches the updated authorization policies if it sees any changes. Apply the second policy only to the istio ingress gateway by using selectors: spec. bar or httpbin. The following policy sets the action field to ALLOW to allow the IP addresses specified in the ipBlocks to access the ingress gateway. For more information, refer to the authorization concept page. Follow the Istio installation guide to install Istio with mutual TLS enabled. See OAuth 2.
