# Configuring Identity-Aware Proxy with Google IAP ## When to Use - When protecting Google Cloud applications (App Engine, Cloud Run, GKE, Compute Engine) with identity-based access - When implementing context-aware access requiring device posture and location verification - When providing secure access to internal tools without VPN or public IP exposure - When needing per-request authentication and authorization for web applications and TCP services - When configuring programmatic access to IAP-protected resources using service accounts **Do not use** for non-HTTP applications that cannot be placed behind an HTTPS load balancer, for public-facing applications that need unauthenticated access, or when applications handle their own authentication and IAP would conflict with existing auth flows. ## Prerequisites - Google Cloud project with billing enabled - IAP API enabled (`gcloud services enable iap.googleapis.com`) - Application deployed behind HTTPS Load Balancer, App Engine, or Cloud Run - Cloud Identity or Google Workspace for user management - Access Context Manager API enabled for access levels - OAuth consent screen configured for the project ## Workflow ### Step 1: Enable IAP on Backend Services Configure IAP for different GCP compute platforms. ```bash # Enable required APIs gcloud services enable iap.googleapis.com gcloud services enable accesscontextmanager.googleapis.com # Create OAuth consent screen gcloud iap oauth-brands create \ --application_title...
