Seguridad en Redes-OpenVAS

Publicado: enero 8, 2013 en Uncategorized

Volvemos de las REPARADORAS vacaciones con Buffer overflows, format strings, race conditions impartido por Iñaki Echevarria”, Algo motivador no! ; así es como habian publicado los administradores del MUSI en la página del Facebook!, pero la verdad considero que las vaciones fueron DESGASTADORAS, el Poteo con los amigos, el Botellón , el estar pensando en la brujita que no me llama! wauuu… que cansado estoy… Pero el sorpredente café bien cargado y el vaso de Coca Kola, han dominado mis ojos cansados ;por lo que Peroma Project ya empezó a dar sus pataditas, y con el apoyo de gente como ustedes muy pronto nacerá. Leyendo uno que otro artículo encontré uno muy interesante de la cual en los próximos blogs una vez haya experimentado con la aplicación les detallaré sobre la instalación y arquitectura de Open VAS. 

Open Vulnerability Assessment System (Open VAS) es. actualmente el codigo abierto para la evaluación de la seguridad más expandido y más profesional en el mercado.El programa es un subproducto de Nessus (antes del 2005). Nessus se inicio como software libre, mutando a un producto con licencia comercial en 2005 al completarse su versión 3.0 . La compañia de Deraison, Tenable Security, se ha concentrado desde entonces en ofrecer soporte técnico para Nessus. La utilidad de un escáner de vulnerabilidades como Open VAS depende de las actualizaciones de su servicio de fuente de datos, que proporciona pruebas de vulnerabilidades de red (NVTs) en un formato especial. Actualmente Open VAS proporciona unas 25,000 NVTs.

Los desarrolladores de Nessus donaron amablemente a la comunidad de software libre el código de la versión 2,2 en 2005 , llevando durante 7 años bajo la licencia de GLP. El proyecto sucesor denominado Open VAS está en su mayoria programado en C, con la excepción de algunos modulos en C++ , y está disponible bajo la licencia  GPLv2. En este campo Nessus llegó a la versión 5,0.

Algunas de las herramientas y complementos más interesantes para Open VAS, conocido como Greenbone Security Solutions, incluye la interfaz web Greenbone Security Assistant (GSA), la interfaz de escritorio Vulnerability Management Control Center (vmcc) o la interfaz avanzada de linea de comandos Vulnerability Management Batch Process Integration(vmbpi), así como la Greenbone Security Explorer, una aplicación web interactiva e independiente, basada en mapas, diseñada para el análisis de informes. Dependiendo de la distribución, las utilidades de Greenbone está usualmente disponibles desde el repositorio de Open VAS o como parte del respectivo paquete.
Solución de Problemas:
En el momento en que un componente de Open VAS comienza a fallar u ocurren otros problemas, el equipo de Open VAS proporciona un script que comprueba la instalación y nos da información para solucionar problemas. Copiamos y pegamos el script en un editor de nuestra elección, guardarlo como openvas-check-setup, luego escribir el comando chmod +x openvas-check-setup comprueba la instalación de OpenVAS 4 y ./openvas-check-setup -v5 ayuda con OpenVAS 5 . Este script comprueba si los servicios necesarios de Open VAS están funcionando y si están aceptando conexiones en los puertos adecuados.
