Tesis de Maestría del año 2012 en eltema Ingeniería - Ingeniería informática, Nota: 100, Materia: Linux, Idioma: Español, Resumen: El uso de servidores Unix y Linux es muy popular ya que estas plataformas se consideran las más estables. Cuando se trata de servidores de gama media y alta, los principales usuarios corporativos han confiado tradicionalmente en Unix y Linux; sin embargo en estas plataformas predecir los ataques hacia servidores es casi imposible (es muy complicado garantizar la seguridad ó la inviolabilidad absoluta de un servidor), por lo que todo administrador de sistemas debe estar preparado. Estos ataques se realizan en días no hábiles, en horas de poco acceso o utilización por parte de técnicos o administradores de sistemas. La utilización de métodos cada vez más sofisticados para el ataque hace necesario tener un plan de contingencia ante cualquier ataque, una mala utilización ó configuración por parte de los encargados de los servidores. Una metodología como ésta permite recuperar a la brevedad el servicio y en su momento de crisis poder mantener los datos fiables y las pruebas intactas, esta metodología puede eliminar errores debido a la crisis por querer recobrar lo más rápido posible el servidor. Esta metodología deja intacto los datos (volátiles y no volátiles) que puedan servir para reconstruir los eventos transcurridos antes, después y a posteriori del compromiso a los servidores para realizarle un análisis forense informático después del accidente. La seguridad en servidores es un proceso que se puede ver comprometido en cualquier momento de la forma menos esperada, si la prevención no funcionó, una buena metodología de contingencia deberá disminuir los costos de este accidente.
