Abstract

PROTEÇÃO DOS RECURSOS DE UM SISTEMA OPERACIONAL O presente documento descreve ferramentas capazes de permitir a um agente de proteção determinar, a partir de uma memória inacessível a partir de um modo de privilégio de sistema operacional, se um ou mais recursos de um sistema operacional foi modificado. Em algumas instâncias, essas ferramentas podem permitir que o agente de proteção resida dentro de um monitor de máquina virtual. Em outras instâncias, as ferramentas podem permitir que o agente de proteção resida dentro de uma partição virtual distinta, provida pelo monitor de máquina virtual. Ao operar fora do modo de privilégio de sistema operacional, o agente de proteção pode se tornar menos vulnerável a ataques por entidades que operam dentro do modo de privilégio de sistema operacional.
