Title (EN) SYSTEM AND METHOD FOR SECURING A COMPUTER COMPRISING A MICROCORE
(FR) SYSTEME ET PROCEDE DE SECURISATION D'UN ORDINATEUR COMPORTANT UN MICRONOYAU
Abstract: front page image
(EN)System and method for securing a computer comprising a microcore. The invention relates to a method of securing a computer comprising a microcore and means for interfacing with at least one virtualized operating system, said microcore comprising a clock drive, a scheduler and an inter-process communication manager and said interfacing means forming at least one virtual machine associated with each operating system and allowing execution of the latter without modification. It comprises, at the level of the interfacing means, the steps of: - intercepting (20) any communication between a means external to the operating system and the operating system, - verifying (24) that predefined rules of access to said external means are validated by said communication; - transmitting (26) the communication to the recipient if the rules are validated.
(FR)L'invention concerne un procédé de sécurisation d'un ordinateur comportant un micronoyau et des moyens d'interface avec au moins un système d'exploitation virtualisé, ledit micronoyau comportant un pilote d'horloge, un ordonnanceur et un gestionnaire de communication inter-processus et lesdits moyens d'interface formant au moins une machine virtuelle associée à chaque système d'exploitation et permettant l'exécution sans modification de celui-ci. Il comporte, au niveau des moyens d'interface, les étapes de : interception (20) de toute communication entre un moyen externe au système d'exploitation et le système d'exploitation; vérification (24) que des règles d'accès prédéfinies audit moyen externe sont validées par ladite communication; transmission (26) de la communication au destinataire si les règles sont validées.
