What it is

API gateways sit between clients and backend services. They enforce authentication, schema validation, throttling, IP filtering, and logging.

Why it matters

APIs are a major attack vector. Gateways standardize protection and reduce direct exposure of backend systems.

How to reduce risk

  • Require API keys or OAuth
  • Implement rate limiting
  • Validate schemas
  • Block direct backend access
  • Monitor for anomalies
  • Enforce TLS everywhere
