Abstract: A method for automatically upgrading an operating system on a computer is provided. The method includes collecting system state information from the computer, and querying a knowledge base to identify state modification actions. Querying the knowledge base may include use of a classification algorithm, for example the k-nearest-neighbours algorithm, to identify non-exact matches in the knowledge base. The system is modified according to identified state modification actions and an upgrade is attempted. In the event that the upgrade fails, information from collected log files is used to update the knowledge base to propose further state modification actions, and the upgrade is attempted again.

Abstract: A method of protecting access to files on a computer file system is disclosed. A kernel-mode file system filter driver controls access to stored policies. Some access policies will cause the file system filter driver to send a request to a user-mode policy configuration service. The user-mode policy configuration service includes features allowing safe autoconfiguration of policies for new applications, and safe reconfiguration of policies for updated applications.

Abstract: A backup recovery and testing method is disclosed. The recovery method restores backed-up systems according to a stored configuration, and collects logs as the restored systems start up. The collected logs are compared with stored baseline logs, by a process which includes parsing the logs into templates and parameters, and identifying anomalies automatically for example by principal component analysis. Anomalies identified may be used to modify the stored configuration.
