HTTPS Always, HTTP Never
Enforce end-to-end TLS 1.3+ encryption across all API endpoints. Modern implementations require automatic certificate rotation and support perfect forward secrecy, mitigating man-in-the-middle risks.
Input Sanitization at Edge
Implement runtime validation for all request inputs using schema-based validation systems. Filter dangerous characters and enforce rate limits at the network edge before backend processing.
OAuth2 + OpenID Connect
Move beyond basic authentication to modern token-based systems. Use short-lived access tokens with refresh token rotation, and integrate with OpenID Connect providers for multi-factor authentication.
Real-Time Threat Detection
Deploy API gateways with WAF (Web Application Firewall) capabilities to identify SQLi, XSS, and other attacks in real-time. Correlate logs with SIEM systems for forensic analysis.
