Y <a rel=\"nofollow\" href=\"\/es\/zhashchita-ot-ddos\/\">la protecci\u00f3n del servidor web contra ataques DDoS<\/a> es la parte m\u00e1s importante de un alojamiento de calidad.<\/p>\n<p>En t\u00e9rminos simples, <strong>un ataque DDoS<\/strong> es una sobrecarga del servidor, de modo que no puede atender a los visitantes. Los hackers toman el control de una red de computadoras y env\u00edan a un servidor objetivo una gran cantidad de solicitudes vac\u00edas. El tama\u00f1o del botnet puede variar desde unas pocas decenas hasta cientos de miles de computadoras. El servidor se ve obligado a responder a todas las solicitudes, no puede manejar la carga y colapsa.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-5179\" src=\"https:\/\/prohoster.info\/wp-content\/uploads\/2017\/09\/zashchita-servera-ot-ddos-atak.png\" alt=\"\" width=\"706\" height=\"424\" \/><\/p>\n<h2>Sistemas de protecci\u00f3n de servidores contra ataques DDoS<\/h2>\n<p><strong>Luchar contra ataques DDoS<\/strong> puede hacerse mediante m\u00e9todos de hardware. Para ello, se conectan cortafuegos al equipo del servidor, que deciden si permitir el tr\u00e1fico adicional. Su firmware contiene algoritmos que determinan la mayor\u00eda de los ataques. Si la potencia del ataque no supera los valores establecidos en la certificaci\u00f3n, el equipo funcionar\u00e1 en modo est\u00e1ndar. La desventaja es el ancho de banda limitado y la dificultad para redistribuir el tr\u00e1fico.<\/p>\n<p><strong>Un enfoque m\u00e1s popular<\/strong> es el uso de redes filtrantes. Dado que el tr\u00e1fico es generado por el botnet, utilizar muchas computadoras en la lucha contra el tr\u00e1fico vac\u00edo es la soluci\u00f3n m\u00e1s \u00f3ptima. La red absorbe el tr\u00e1fico, lo filtra y solo el tr\u00e1fico verificado y de calidad de usuarios reales llega al servidor objetivo. La principal ventaja de este enfoque es la posibilidad de configurar la protecci\u00f3n de manera flexible. Los hackers avanzados ya han aprendido a enmascarar el tr\u00e1fico malicioso como si fuera tr\u00e1fico de visitantes normales. Solo un especialista en protecci\u00f3n de informaci\u00f3n experimentado puede reconocer el tr\u00e1fico da\u00f1ino.<\/p>\n<p>Para protegerse contra tales ataques, los proveedores y las empresas de alojamiento crean redes que filtran el tr\u00e1fico. En caso extremo, es posible conectarse a nodos externos de limpieza de tr\u00e1fico.<\/p>\n<p>La arquitectura de la red consiste en tres capas: enrutamiento, procesamiento de paquetes y aplicaciones. A nivel de enrutamiento, se distribuye uniformemente el flujo entre los nodos de la red gracias a enrutadores de alto rendimiento. En el nivel de procesamiento de paquetes, varios dispositivos de reserva mutua filtran el tr\u00e1fico entrante mediante algoritmos especiales. En el nivel de aplicaciones se realiza el cifrado, descifrado y procesamiento de solicitudes. Si es necesario, se pueden leer informes sobre la capacidad y duraci\u00f3n de los ataques, as\u00ed como informes sobre la limpieza.<\/p>\n<p><em>Empresa <a href=\"https:\/\/prohoster.info\/es\/hosting\/unlim-khosting\/\"  data-wpil-monitor-id=\"3241\">ProHoster proteger\u00e1 su sitio web<\/a> de ataques DDoS de hasta 1,2 Tb\/s.
