  • Publication number: 20060242705
    Abstract: An intrusion detection system for a computer network includes a knowledge database that contains a baseline of normal host behavior, and a correlation engine that monitors network activity with reference to the knowledge database. The correlation engine accumulating information about anomalous events occurring on the network and then periodically correlating the anomalous events. The correlation engine generates a worm outbreak alarm when a certain number of hosts exhibit a role-reversal behavior. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.
