  • Connection based denial of service detection
    Patent number: 8191136
    Abstract: A system for detecting network intrusions and other conditions in a network is described. The system includes a plurality of collector devices that are disposed to collect data and statistical information on packets that are sent between nodes on a network. An aggregator device is disposed to receive data and statistical information from the plurality of collector devices. The aggregator device produces a connection table that maps each node on the network to a record that stores information about traffic to or from the node. The aggregator runs processes that determine network events from aggregating of anomalies into network events.
    Type: Grant

  • Architecture to thwart denial of service attacks
    Patent number: 7657934
    Abstract: A monitoring device is disposed to thwart denial of service attacks on a data center. The monitoring device is a device that collects statistical information on packets that are sent between a network and the data center for a plurality of customers by examining traffic as if the device was disposed on links that are downstream from links that the provisioned monitor is disposed on.
