El sitio permite verificar la aplicaci\u00f3n por parte de los proveedores de la tecnolog\u00eda de filtrado de rutas incorrectas y evaluar la implementaci\u00f3n del soporte para RPKI. <\/p>\n<p>Muchos operadores siguen estando desprotegidos ante la recepci\u00f3n de anuncios BGP de subredes con informaci\u00f3n err\u00f3nea sobre la longitud de la ruta, lo que dirige el tr\u00e1fico de tr\u00e1nsito a trav\u00e9s de proveedores externos. Cada vez son m\u00e1s frecuentes los casos de uso de BGP para ataques, en los que los delincuentes, mediante la compromisi\u00f3n de la infraestructura de los proveedores, organizan el redireccionamiento y la interceptaci\u00f3n de tr\u00e1fico para sustituir sitios espec\u00edficos a trav\u00e9s de un ataque MiTM, sustituyendo las respuestas DNS. <\/p>\n<p>La soluci\u00f3n al problema es la implementaci\u00f3n de un sistema de autorizaci\u00f3n de anuncios BGP basado en RPKI (Infraestructura de Clave P\u00fablica de Recursos), que permite determinar si el anuncio BGP proviene del propietario de la red o no. Al utilizar RPKI para sistemas aut\u00f3nomos y direcciones IP, se construye una cadena de confianza desde IANA hacia los registradores regionales (RIR), luego hacia los proveedores (LIR) y finalmente hacia los consumidores finales, lo que permite a terceros verificar que la operaci\u00f3n con el recurso fue realizada por su propietario. Lamentablemente, a pesar de los problemas, RPKI a\u00fan no es utilizado por la mayor\u00eda de los proveedores. Un nuevo servicio de Cloudflare permite rastrear a los operadores problem\u00e1ticos y atraer la atenci\u00f3n p\u00fablica hacia ellos.<br \/>\n<center><noindex><a rel=\"nofollow\"
