A software security application for a Windows~ OS based electronic computer system provides an isolated User environment which protects a User from unauthorized access to and manipulation of data on the system. The security software implements an isolated User file system and provides process/IPC isolation, Windows~ registry isolation, network interface isolation, and isolated administrative control on the computer system. Interactive components of the system include an execution hook component that traps system calls, a job object component that creates/destructs, manages and manipulates job objects, a system call hook component for trapping and filtering all Windows registry I/O requests, a file system block device driver for mounting/unmounting the isolated User file system, a file system/filter driver, a network interface/NDIS hook component, and an environment handler. The environment handler provides the overall management interface for other system components, allowing definition of rules, managing authentication and other control/management functions.

Une application de sécurité logicielle pour un système informatique électronique OS Windows ® fournit un environnement d'utilisateur isolé qui protège l'utilisateur contre l'accès non autorisé aux données et à leur manipulation sur le système. Le logiciel de sécurité met en oeuvre un système de fichiers d'utilisateur et permet l'isolement IPC/procédé, l'isolement du registre Windows ®, l'isolement d'interface réseau et la commande administrative isolée sur le système informatique. Les composants interactifs du système sont, entre autres, un composant crochet d'exécution qui piège les appels du système, un composant objet de travail qui crée/détruit, gère et manipule les objets de travail, un composant crochet des appels du système pour piéger et filtrer toutes les demandes E/S de registre Windows, un pilote de dispositif bloc de système de fichiers pour monter/démonter le système de fichiers Utilisateur isolé, un pilote de filtre/système de fichiers, un composant crochet NDIS/interface réseau et un gestionnaire d'environnement. Le gestionnaire d'environnement fournit l'interface de gestion globale pour les autres composants du système, et permet ainsi la définition de règles, la gestion de fonctions d'authentification et d'autres fonctions de gestion/commande.
