| Area | Recommended Controls | |------|-----------------------| | | Use TLS 1.3 only; enable OCSP Stapling , HSTS , certificate pinning ; rotate certs via ACME automatically. | | Authentication | Enforce mutual TLS for internal services; use OAuth2 / OIDC for external API clients; add MFA for admin UI. | | Access Control | Implement Zero‑Trust ACLs (allow list per‑origin); block outbound traffic from unknown clients. | | DPI/WAF | Deploy signature sets from OWASP CRS , enable SQLi/XSS detection, limit request body size. | | Rate Limiting | Global per‑IP quota (e.g., 100 rps) + per‑endpoint burst limits; use Token Bucket algorithm. | | Logging & Auditing | Write logs in JSON ; forward to ELK/EFK stack; enable tamper‑evident storage (append‑only). | | Patch Management | Automate OS & software updates via Ansible or Chef ; schedule rolling restarts with drain‑mode . | | Isolation | Run each proxy component inside a container or VM with minimal privileges; use seccomp , AppArmor , or SELinux profiles. | | Backup & Disaster Recovery | Snapshot configuration repo nightly; replicate cache metadata across sites; test failover quarterly. |
