La verificaci\u00f3n se reduce a una prueba matem\u00e1tica de la correcci\u00f3n del funcionamiento de seL4, lo que indica que cumple completamente con las especificaciones establecidas en un lenguaje formal. La prueba de confiabilidad permite usar seL4 en sistemas cr\u00edticos basados en procesadores ARM64, que requieren un alto nivel de seguridad y garantizan la ausencia de fallos.     <\/p>\n<p>Inicialmente, el microkernel seL4 fue verificado para procesadores ARM de 32 bits, y m\u00e1s tarde para procesadores de 64 bits x86 y RISC-V. La verificaci\u00f3n garantiza que en caso de fallo en una parte del sistema, se evitar\u00e1 que este fallo se propague al resto del sistema y a sus partes cr\u00edticas. En el contexto de la seguridad, la verificaci\u00f3n confirma que el n\u00facleo proporciona el nivel adecuado de aislamiento de las aplicaciones, evita que accedan a informaci\u00f3n sin autorizaci\u00f3n y asegura que en caso de compromiso de aplicaciones secundarias, el ataque no se propagar\u00e1 a aplicaciones cr\u00edticas.    <\/p>\n<p>La arquitectura del microkernel seL4 es notable por la delegaci\u00f3n de partes de la gesti\u00f3n de recursos del n\u00facleo al espacio del usuario y por el uso de los mismos mecanismos de control de acceso para estos recursos que para los recursos de usuario. El microkernel no proporciona abstracciones de alto nivel listas para gestionar archivos, procesos, conexiones de red, etc. En su lugar, ofrece solo mecanismos m\u00ednimos para gestionar el acceso al espacio de direcciones f\u00edsicas, interrupciones y recursos del procesador. Las abstracciones de alto nivel y los controladores para interactuar con el hardware se implementan por separado sobre el microkernel en forma de tareas que se ejecutan en el nivel de usuario. El acceso de estas tareas a los recursos disponibles en el microkernel se organiza mediante la definici\u00f3n de reglas.<br \/>\n<br \/>Fuente: <a content=\"nofollow\" rel=\"nofollow\"
