Patent

CA 2617204

A security system provides a defense from known and unknown viruses, worms, spyware, hackers, and unwanted or unknown software. The system can implement centralized policies that allow an administrator to approve, block, quarantine, or log file activities. The system maintains file meta-information in the hosts and in the server. A host detects file operations which can cause changes to file content or file name, and updates the host and/or server meta- information as a result. Changes in server meta-information are made available to hosts.

L'invention porte sur un système de sécurité assurant la parade des virus, vers, logiciels espions, pirates informatiques connus et inconnus et de logiciels non désirés ou inconnus. Le système peut mettre en oeuvre des lignes de conduite centralisées qui permettent à l'administrateur d'approuver, de bloquer, de mettre en quarantaine ou d'enregistrer des activités de fichiers. Le système conserve des méta-informations de fichiers dans les hôtes et dans le serveur. Un hôte détecte des opérations de fichiers pouvant générer des modifications quant au contenu ou au nom du fichier et met à jour les méta-informations de l'hôte et/ou du serveur sous forme d'un résultat. Les modifications apportées aux méta-informations du serveur sont mises à la disposition des hôtes.
