Abstract
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.
