EBA outsourcing guidelines demand more than a checklist. They demand proof. Proof that your secure API access proxy does what you say it does, under the worst possible conditions. The bar isn’t “working on paper.” The bar is “operational while under stress, compliant under review, and trusted by stakeholders.”
The foundation is control. Know exactly how your proxy handles authentication, encryption, and request logging. Avoid shared secrets scattered in code repositories. Use centralized credential vaults. Every API key and token must have a lifecycle, from creation to expiry, with no exceptions.
Segmentation is non‑negotiable. Keep public endpoints, internal APIs, and partner integrations in separate zones. Map out the flow from user request to backend system and catalog every connection. Reduce the blast radius by limiting what every individual proxy instance can reach.
The EBA guidelines make auditability a priority. That means timestamped access logs, immutable storage, and the ability to filter by user, endpoint, or IP in seconds. Logs are useless if you can’t pull the right record when you need it.
Security hardening matters at the proxy layer. Disable unused HTTP methods. Enforce strict TLS configurations. Inspect payloads for anomalies before they touch your backend. Automate these checks so they run without human intervention.
