# Pattern: API Gateway as Security Boundary
|
|
|
|
Status: seed
|
|
Readiness target: RL3 production
|
|
Primary owners: Railiance platform, product repos
|
|
Genesis family: Application/API security
|
|
|
|
## Problem
|
|
|
|
Public APIs need consistent edge protections before traffic reaches
|
|
product services.
|
|
|
|
## Context
|
|
|
|
Use this pattern for public HTTP APIs, tenant-facing APIs, admin APIs,
|
|
ingress paths, rate limiting, schema checks, authentication, and edge
|
|
logging.
|
|
|
|
## Forces
|
|
|
|
- Gateways can centralize common controls.
|
|
- Applications still need local authorization and validation.
|
|
- Edge policies must not hide tenant or object-level checks.
|
|
- Admin APIs require stricter exposure rules than public product APIs.
|
|
|
|
## Solution
|
|
|
|
Place a managed gateway at API ingress to enforce authentication
|
|
prechecks, TLS, rate limits, request size, schema constraints, logging,
|
|
and routing before forwarding to application enforcement points.
|
|
|
|
## Verification
|
|
|
|
- Unauthenticated or malformed requests are rejected at the edge.
|
|
- Rate limits and abuse controls are active.
|
|
- Admin surfaces use separate routes and stronger controls.
|
|
- Application-level object authorization still runs behind the gateway.
|
|
|
