  • Patent number: 8205255
    Abstract: A system to prevent content spoofing by detecting phishing attacks is provided. The system checks each webpage visited by a user and determines if the page is legitimate. To determine if a page is legitimate, the system employs fingerprints to check how similar the browsed page is with respect to an original page. If the similarity between browsed page and the original page is found to be more than a preset threshold, then the browsed page is considered to be a spoofed page. Access to the spoofed page is then either denied and/or an alarm is triggered.

  • 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. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

  • Publication number: 20060037077
    Abstract: An intrusion detection system and method for a computer network includes a processor and one or more programs that run on the processor for application inspection of data packets traversing the computer network. The one or more programs also obtaining attribute information from the packets specific to a particular application and comparing the attribute information against a knowledge database that provides a baseline of normal network behavior. The processor raises an alarm whenever the attribute information exceeds a predetermined range of deviation from the baseline of normal network 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. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
