摘要： A plurality of flow collector devices is disposed to collect flow information on a network. Duplicate flow records received from the flow collectors are eliminated by determining whether a pair of flow records has the same, source and destination flow identifiers and were received within a predefined time-period. Non-duplicated flow records received from the plurality of flow collector devices are stored and used to produces a connection table that maps each node on the network to a record that stores information about traffic to or from the node from non-duplicated flow records. The connection table stores statistical information of packets on the network based on a time-slice basis.

摘要： 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.

摘要： A system architecture for thwarting denial of service attacks on a victim data center is described. The system includes a first plurality of monitors that monitor network traffic flow through the network. The first plurality of monitors is disposed at a second plurality of points in the network. The system includes a central controller that receives data from the plurality of monitors, over a hardened, redundant network. The central controller analyzes network traffic statistics to identify malicious network traffic. In some embodiments of the system, a gateway device is disposed to pass network packets between the network and the victim site. The gateway is disposed to protect the victim site, and is coupled to the control center by the redundant hardened network.
