А пока давайте разберём важные **идеи**. Эти концепции применимы и к другим типам веб‑API. 💡

## Безопасность — HTTPS { #security-https }

В [предыдущей главе про HTTPS](https.md){.internal-link target=_blank} мы разобрались, как HTTPS обеспечивает шифрование для вашего API.

Также мы увидели, что HTTPS обычно обеспечивает компонент, **внешний** по отношению к серверу вашего приложения — **TLS Termination Proxy**.
