tls_1_3_termination

Terminación TLS 1.3 en el API Gateway para cifrar todo el tráfico entre clientes y el sistema. TLS 1.3 elimina handshakes inseguros y reduce la latencia de conexión con 0-RTT.

When to use

Configurar en el api_gateway_agent (Nginx) como punto de terminación TLS para todo el tráfico externo. Todo endpoint público debe estar protegido con TLS 1.3.

Instructions

  1. Generar certificados con cert-manager o Let's Encrypt.
  2. Configurar Nginx:
    ssl_protocols TLSv1.3;
    ssl_prefer_server_ciphers off;
    ssl_certificate /etc/ssl/certs/server.crt;
    ssl_certificate_key /etc/ssl/private/server.key;
    
  3. Habilitar HSTS: add_header Strict-Transport-Security "max-age=63072000; includeSubDomains" always;.
  4. Configurar OCSP stapling para validación rápida de certificados.
  5. Deshabilitar TLS 1.0/1.1/1.2 en producción.
  6. Probar con openssl s_client -connect host:443 -tls1_3.
  7. Monitorizar expiración de certificados con alertas 30 días antes.

Notes

  • TLS 1.3 reduce el handshake de 2-RTT a 1-RTT (0-RTT para reconexiones).
  • No usar certificados self-signed en producción; siempre Let's Encrypt o CA interna.
  • Redirigir HTTP a HTTPS automáticamente: return 301 https://$host$request_uri.
