Shni 781f4398a4 feat: Implement comprehensive security enhancements and deployment guide for AmayoWeb

- Added a detailed deployment guide (DEPLOYMENT_GUIDE.md) for frontend and backend setup.
- Created an index documentation (INDEX.md) summarizing changes and available resources.
- Established Nginx security configuration (NGINX_SECURITY_CONFIG.md) to protect backend IP and enforce rate limiting.
- Developed a backend security guide (SECURITY_BACKEND_GUIDE.md) outlining security measures and best practices.
- Introduced middleware for security, including rate limiting, CORS, and Cloudflare validation.
- Updated frontend components and services to improve security and user experience.
- Implemented logging and monitoring strategies for better security oversight.

Configuración de Nginx para Backend Seguro

/etc/nginx/sites-available/api.amayo.dev

Configuración para ocultar la IP del servidor y mejorar la seguridad

Rate limiting zones

limit_req_zone $binary_remote_addr zone=api_limit:10m rate=30r/m; limit_req_zone $binary_remote_addr zone=auth_limit:10m rate=3r/m; limit_conn_zone $binary_remote_addr zone=conn_limit:10m;

Bloquear IPs que no sean de Cloudflare

geo $realip_remote_addr $cloudflare_ip { default 0;
