A security system provides a defense from known and unknown viruses, worms, spyware, hackers, and social engineering attacks. The system can implement centralized policies that allow an administrator to approve, block, quarantine, or log file activities. The system stores meta-information for files relating to security and at defined times after a file or a file hash is first received, performs security related analyses from a central server. Analysis results are stored on the server, and the server can automatically change file meta-information. Changes in file meta-information are provided to hosts.
