Programa de auditoría automática Titan, que detecta problemas de seguridad en la máquina local

Para corroborar la inseguridad de los sistemas Unix instalados tal y como se distribuyen, o mínimamente configurados, hemos hecho la prueba con uno de los sistemas considerados más seguros: Solaris, de la empresa Sun Microsystems, Inc.. Hemos instalado Solaris 7 sobre un PC, cerrado la mayoría de servicios ofrecidos (en /etc/inetd.conf), y controlado el acceso a otros (telnet, finger, ftp...) mediante TCP Wrappers: justo lo que la mayor parte de administradores harían antes de poner el sistema a funcionar. Tras estos pasos, hemos ejecutado el programa de auditoría automática Titan, que detecta problemas de seguridad en la máquina local (para más información sobre este software se puede consultar [FPA98]).

Instalación de Titan

Hemos elegido Titan justamente por ser uno de los programas más fácilmente instalables sobre SunOS o Solaris: al tratarse de un conjunto de shellscripts, el administrador no ha de preocuparse por ningún proceso de compilación (con los posibles errores que éste puede causar), ni conocer técnicas avanzadas de seguridad para poder utilizarlo (como otros programas que presentan una multitud de opciones diferentes que se pueden combinar entre ellas, de forma que quien los quiera utilizar debe conocer bastante bien ciertos términos de Unix y de la seguridad, que no suelen ser triviales). Tanto la instalación de Titan como su ejecución son muy sencillos.
Para instalar Titan, una vez desempaquetado el fichero, hemos de ejecutar simplemente
Titan-Config, con la opción -i (la opción -d desinstala el software. El programa de instalación nos preguntará si deseamos hacer copias de seguridad de los ficheros que se modifiquen al ejecutar Titan; por nuestra seguridad, podemos decirle que sí (y):

anita:/export/home/toni/Security/Tools# gzip -d Titan,v3.0.FCS.tar.gz
anita:/export/home/toni/Security/Tools# tar xvf Titan,v3.0.FCS.tar

anita:/export/home/toni/Security/Tools/Titan,v3.0.FCS#

Una vez instalado Titan (todo a partir del directorio actual, no genera ficheros en ningún otro lugar de nuestros sistemas de archivos) podemos ejecutar ya el programa de auditoría, con la opción -v para que no realice ningún cambio en nuestro sistema, sino que simplemente se limite a informarnos de los posibles problemas de seguridad que podemos tener; si deseamos ver el funcionamiento de cada uno de los shellscripts invocados por Titan, podemos utilizar la opción -i, y si lo que queremos es solucionar los problemas detectados, la opción -f (cuidado si hacemos esto, la política de seguridad de Titan es tan estricta que podemos dejar al sistema sólamente utilizable por el root).

Ejecución de Titan
En nuestro caso, queremos que Titan nos informe de los problemas de seguridad que detecte, pero que no los solucione él:

Mirando por encima el resultado ofrecido por Titan, vemos que ha detectado <casi 50 posibles problemas! (cada mensaje FAILS CHECK denota una alarma, mientras que cada mensaje PASSES CHECK denota un test satisfactorio).

A la vista de estos resultados, y teniendo en cuenta que hemos utilizado una versión más o menos moderna de Solaris (la versión 7 10/98, si hubiéramos comprobado una versión de Solaris o SunOS más antigua habríamos detectado seguramente muchos más problemas), parece claro que un sistema Unix instalado tal y como se distribuye, o con una configuración de seguridad mínima -nuestro caso-, representa un grave problema ya no sólo para la máquina en cuestión, sino para toda la red en la que trabaja. Por tanto, el uso de cualquier herramienta que nos ayude a solucionar, o al menos a localizar problemas, va a ser útil.
