| Aspect | Recommendation | |--------|----------------| | | Always use HTTPS with a valid certificate (avoid self-signed in production). | | Authentication | Prefer token-based over basic auth; implement short token expiry. | | Network | Place WinCC server in a protected OT network; use a reverse proxy or VPN for external access. | | Permissions | Grant minimum necessary rights to REST API users (e.g., read-only if possible). | | Audit | Enable WinCC audit trail to log API writes. | | Rate limiting | WinCC does not enforce by default – implement at client or firewall level to avoid overload. |

It allows for management and data exchange with user archives (recipes, production data).
