\u00bfQu\u00e9 es un host basti\u00f3n?<\/span><\/h2>\n

Un host basti\u00f3n es un ordenador especializado que est\u00e1 deliberadamente expuesto en una red p\u00fablica.<\/strong> Desde la perspectiva de una red segura, es el \u00fanico nodo expuesto al mundo exterior y, por lo tanto, es muy propenso a sufrir ataques.<\/p>\n

Se coloca fuera del cortafuegos<\/a> en sistemas de un solo cortafuegos o, si un sistema tiene dos cortafuegos, a menudo se coloca entre los dos cortafuegos o en el lado p\u00fablico de una zona desmilitarizada (DMZ).<\/p>\n

El host basti\u00f3n procesa y filtra todo el tr\u00e1fico entrante e impide que el tr\u00e1fico malicioso entre en la red, actuando de forma muy parecida a una pasarela.<\/p>\n

Los ejemplos m\u00e1s comunes de hosts basti\u00f3n son los servidores<\/a> de correo, sistema de nombres de dominio, Web y Protocolo de Transferencia de Archivos (FTP)<\/strong>. Los cortafuegos y los routers tambi\u00e9n pueden convertirse en hosts basti\u00f3n.<\/p>\n

\n

Definici\u00f3n de Bastion Host<\/span><\/h2>\n

El nodo<\/a> host basti\u00f3n suele ser un servidor muy potente con medidas de seguridad mejoradas y software personalizado. Por lo general, aloja una sola aplicaci\u00f3n porque tiene que ser muy bueno en lo que hace. El software suele ser personalizado, propietario y no est\u00e1 disponible al p\u00fablico.<\/p>\n

Este host est\u00e1 dise\u00f1ado para ser el punto fuerte de la red y proteger el sistema que tiene detr\u00e1s. Por lo tanto, suele someterse a un mantenimiento y auditor\u00eda regulares.<\/strong> A veces, los hosts basti\u00f3n se utilizan para atraer ataques, de modo que se pueda rastrear el origen de los mismos.<\/p>\n

Para mantener la seguridad de los hosts basti\u00f3n, se eliminan todos los programas, demonios y usuarios innecesarios. El sistema operativo<\/a> se actualiza continuamente con las \u00faltimas actualizaciones de seguridad y se instala un sistema de detecci\u00f3n de intrusos.<\/p>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"
