Protect Perimeter Ingress: Details and Roadmap
Feature California Delhi Edinburgh Beyond API Gateway Single Ingress Point for ALL HTTPS traffic (no HTTP) using Kong X TBD Authentication Simple JWT based authentication (via kong plugin) Oauth based AuthN (Client Credentials, Bearer Token Flow) Identity Management Features (User Lifecycle Management, password change, revoke) Authorization None Via Kong ACL plugin that enables group based AuthZ TLS Server Side Only Primary Cert stored in Vault Mutual Certificates Service to Service Enabled via one of (mutual certs or Token based AuthN) Secure service registration (Considering Consul Connect) IIC Endpoint Security Best Practices Reference: Secure Communications
