Abstract
(EN)
According to aspect of the disclosure, there are provided methods and apparatus for connecting a peripheral device to a computer system, including an apparatus for interfacing with a peripheral device, the apparatus comprising a port configured to couple to the peripheral device, a processor, a memory coupled to the processor and comprising a software module comprising instructions that when executed on the processor protect the device from a peripheral device coupled to the port, and a hardware security controller coupled to the port, the hardware security controller configured to monitor execution of the software module by the processor and to disable the port in response to determining that the software module is not executing.
(FR)
Selon un aspect, l'invention concerne des procédés et un appareil pour connecter un dispositif périphérique à un système informatique, y compris un appareil pour l'interfaçage avec un dispositif périphérique, l'appareil comprenant un port configuré pour coupler le dispositif périphérique, un processeur, une mémoire couplée au processeur et comprenant un module logiciel comprenant des instructions qui, lorsqu'elles sont exécutées sur le processeur, protègent le dispositif d'un dispositif périphérique couplé au port, et un contrôleur de sécurité matériel couplé au port, le contrôleur de sécurité matériel étant configuré pour surveiller l'exécution du module logiciel par le processeur et pour désactiver le port en réponse à la détermination du fait que le module logiciel n'est pas en cours d'exécution.
